Owner is lucky, timing failure can blow those engines apart! Good vid. I like to watch and see how other people go about things. Can pick up even the smallest things which helps
I really enjoy every one of your videos you make, Schrodingers. I've currently just finished my Level 1 Light Vehicle Maintanance and Repair at college and I have to say, without sounding too much like I'm kissing your arse here, your videos have helped me a lot with the practical side of my course - so thank-you so much!
As a trained glorified parts changer (aka us army mechanic) I have always tried to find a better way to do this kind of work. I must tell you your videos have given me great knowledge and ability to do more than change parts for a diagnosis. I love watching your videos because everyone of them is like an episode of house. Keep up the great work and I'm proud to be one of the 2%
I have viewed this video 2 or 3 times just to make sure I heard all of your snide remarks. You honestly need to write a book. I would hate to be a mechanic who had a car before you looked at it...I would be so depressed. I always make it a point to watch your videos, not only for the excellent content, but the humor alone is worth the price of admission. Keep it up, sir.
98%er's that think inside the boxwrench step out and use the open end (17mm) as the special tensioner release tool lol. Do love the videos, watch them all. Follow-up on setting timing belt tensioner was very timely and useful last weekend on own jetta. Thanks!
😂😂 yeah the pliers on the belt tensioner scene was painful to watch and hear😂 i aint no mechanic but the Bentley manual tells you to use a open ended wrench
Great video! I had a feeling it was timing chain/belt related. I have to admit I used to be part of that 98% but every since your fuel trim videos my life has been changed
Bennie Morgan We all start off as 98%ers actually. A few recognize that and change, but Some are too lazy to change and most by far don't even realize they are the 98%!!
Once again I would love to give a shout out to all the armchair mechanics who thumbs down the video as soon as it's released and yet they still watch the whole thing, learn stuff they could never do themselves, and despite watching all my videos they still couldn't diagnose a diaper rash on a baby with sandpaper in its crack. Just sayin.... As for the 2%ers- a big hello and thanks for your support!!
Schrodingers Box Nicely said, Matt. Don't worry about the boofheads giving you a thumb down that will just result in more of your regulars showing their appreciation and giving you a big fat thumbs up! Keep up the good work, mate. :-)
Schrodingers Box Hi Matt, in cars VW is possible diagnostic this problem with VAG-COM, look the parametre "Angle Sincr" In the engines diesel if "Angle Sincr" is more 4º the difference between CKP and CMP the engine don´t start. When that happens in VAG COM can see for example: Camshaft Position Sensor (G40): Signal Out of Range. Greetings from Spain. =)
You laugh. Theres some moms i know that cant figure why a baby is crying...but i dont want to use powder...they could inhale it lol. Then i hand em a tube of ass cream....problem solved...im an idiot. Lol
Schrodingers Box Take it easy, if you let that stuff get under your skin, you'll never survive TH-cam, stress kills. People are idiots and everyone knows it.
Matt great lesson to all the people out here in you tube land that think all there is to diagnosing a modern vehicles is plugin in your whatever and getting a code(s) are sorely misinformed or downright ignorant. Verify,confirm and validate.Thanks again.
Daniel Wells Thanks Daniel. BTW "wells" is perfect last name for a diagnostic mechanic lol. Any relation to the company? Yeah TH-cam blows- I actually decided to look at the market for videos on the timing belt change- NONE showed the correct procedure for adjusting tension and in fact the most watched video on the subject of all (almost 300K views) didn't even mention tensioning- in fact the hack put the belt right back on the same timing components with no tensioning adjustment!!! I feel responsible to now make a video of the tension adjustment just so TH-cam will have a resource for this engine.
Great videos you have here man! I gotta say, you and Eric the car guy are the only two car channels I watch now! i'm desperately trying to emerge from being a parts changer and your videos are helping me a lot!
+coolbluelights Yeah ETCG is a great guy and all but he's really geared more for beginners. You won't find me changing oil or a radiator here lol. I actually stopped watching him years ago. He's a great guy though but I just get bored dizzy watching wrenches spin and spin and spin and spin...
coolbluelights You should also check out my friend Paul Danner's channel channel name is scannerdanner. He's even a major step up from what I do. Check his channel out!
No special tool needed for the serpentine belt tensioner. An open end wrench (17mm?) will fit on the same tab where you put the vice grip. On my VW Eurovan, the "special tool" for the same function is an 8mm bolt.
Yeah i know, as soon as people from murica or canada (or where ever) see an euro car. They freak out. Do some reading. I know, alot of german cars (like my passat -98 v6) needs special tools and all that. But that's usally only for the dealership. They wanna make some money maybe? But you REALLY don't need em. 9/10 you can get by them. And in this case, NO there are no special tool. It's 8mm allen head bolt so you can turn it? I can't remember but there are like a regular 10 mm bolt that you can remove it with...
I'm looking for the egr valve or combi valve on my 99' vw golf gti and cant seem to find it or figure it out anywhere else. Hoping you might be able to help me out?
Bob Moore Yes I agree with you- there is definitely a satisfaction to designing your own work-arounds for special tools- especially ones that cost a lot. I have a whole collection of specialty tools I've made over the years, but the difference is most of them will apply to many, many makes and models. To make a specialty tool for a single model that I may never see again is just not possible because nowadays I have other cars waiting in the queue and I can't spend 2 hours making a tool to replace a drivebelt.
Hi,Just like to say that I think the reason for strange shaped and odd tools here in Europe is so we are deterred from doing any work to our cars and take them to the dealership and the car maker can squeeze you for even more cash.Thanks for sharing my friend 👍🏻
Thanks for sharing ,,,, thought I was caught up seeing most of your videos but it seems youtube knows better sending me all the ones I missed from years ago but just as good as a new one , timeless !
No special tool required for the removal of the serpentine belt. 16mm wrench to slacken off the tensioner. There is also a hole in the tensioner that you can insert a 4mm drill / pin to lock it in the loose position.
As always, a Great video. As for those that give you the thumbs down, you need to feel sorry for them to some extent. What most people don't realize, is that - Stupidity is a real illness, and there is no known cure for it. Thank you for all your efforts at making these videos, so we can all benefit from your knowledge and the " No Nonsense Approach" that you use to come to the right conclusion, in the fastest time possible. Best regards, Joe
***** Ah I totally forgot- you work on VW's all the time on your channel don't you? Yeah I had a lot of trouble researching for sure if it is interference or not. But is sounds very obvious no valve damage was done.
man, i joined you recently and now i have alot of respect for you, you are indeed a professional. please continue making more videos and also kindly recommend me a cheap scan tool which can make diagnostics a little easier
***** It is self contained, however connecting to a laptop will allow you a bit better analysis (e.g. generate graphs, etc). I also own an old Mac TaskMaster that I use in the field sometimes. You can find them on Ebay a lot. It's nothing short of excellent for a scantool under $400.
Thanks a lot for your info-clip and yes, we do have the same two-liter engine in a Jetta and yes, it is trying to tell me something (=being noisy) and yes, I'll check the belt you've shown!
man I think even A 98%'er such as myself could have diagnosed that! Good job Matt. I can not believe shops can miss something like this and charge for giving the totally wrong diagnosis.
Great video. Not surprised that the previous "professional" shop never figured it out. Goes to show....most issues can be pretty obvious with a little unbolting yourself. Also, it pays to know a guy who knows his way around an engine. I havent taken my car to a "pro" shop in years. What I can't do myself....I take to my Mechanic Guy...who isn't a licensed mechanic. (BTW, I own a 2011 Jetta, 2.5L) cheers!
Don't worry Matt, it drives us crazy too, european aspiring to be 2%er here. Even worse than the special tools needed is the lack of physical workspace that occurs in the engine bay of european cars as opposed to north american ones. Granted, I don't like 98% (I chose a random number here :)) of american cars (although I must admit the Trans Am is a beauty), but they are surely easier to work on. In Europe we love to overcomplicate things and it applies to many real life situations as well, unfortunately. As a side note, it's now about 4 months that I'm binging on your videos on YT and SBQM and the things I'm learning are just amazing. Your way of explaining never gets tiring and that combined with a sour, harsh sarcasm makes it for a really entertaining time. I can't help but crack a laugh when you get aggravated by the inevitable plugs+wires or sensor swap (I used to do it too when I didn't have a clue). It's just hilarious! Keep up the good work man!
White Tiger Thanks Tiger. I actually charged him a total of just $250 for everything. Not bad for a timing belt, I think. And sure as hell better than a $3000 camshaft!!
I don't understand how Scotty Kilmer has 338k subscribers and you only have 22k. As a full time truck mechanic there's plenty of thingS I don't understand on automobiles. But I can tell you right now I learn waaaaay more from you than Scotty, "the Emmy award winning mechanic"
asavage1576 Thanks but I know exactly why- its because Scotty caters to the masses. Most people by far will lose attention in 3 minutes. They like the idea that they can become an "expert" by watching just a 3 minute video and never getting their hands dirty. Then they take their expertise to the chat room and forums and spread the disease of ignorance right from their armchair.
The requirement for specialist tools for European cars is entirely deliberate, manufacturers don't want us tinkering with their cars when they have a dealer network that will happily charge us £100 per hour to carry out the work.
It's actually a very weak act. Most of the time technicians just improvise like in this video because it is too much effort to leave the job to find the silly tool. I like all this nonsense because it helps to make European cars very cheap to buy used.
That's a VW Mk4. Ask me how I know! I had that exact same sound on a 2002 Vw Golf, started about ten miles before the car wouldn't go anymore because the timing belt lost too many teeth. As it turns out, the 2.0 is sometimes listed as interference, sometimes not. Valve damage can occur. Anyway, thanks! I've been trying to figure out what made the teeth come off like that, and a loose tensioner makes sense. Wish me luck putting it back together without needing to replace the head.
Yeah good luck- I too have seen it listed both in interference and non-interference so I am not even sure! Either way, hopefully the valves are still straight!
what happened to me i did not change the timing belt or forgot to !! im original owner of a 02 vw golf 2.0 gl bought it with 16 miles on the OD !! im a bad owner !! BUT the timing belt did not break on its own until 159k miles !!! thats a long life for a timing belt !!! sux i had to replace all the exhaust valves !!! cost me 1200 dollars !! live and learn !!
Thank you you are a smart man my VW bug was making the same noise for about two days I came home from work to shut it off had to get back out to go to the grocery store and at start up it went capoop smoke coming from the engine..
Excellent video! Joy's husband here. Small time repair guy. Yes; germans make a lovely engine. (Got a BMW 325xi with 300k. Motor is like NEW. Obviously; well maintained!) AGREE completely: the special tool thing is wildly annoying. Diagnostic difficulty also. Yeah; i got a 99 Passat with that HORRENDOUS "rattling" in the top of the engine. Gotta be like yers; tensioner out to lunch. Some other videos indicate a 'chain' in the rear of the engine. (another brilliant german anomaly. vis a vis: the HORRIBLE german V6 in the last model Ford Explorer. Goofed up all the time due to lack of oil changes.) Great engines...BUT; you better do the maintenance dawg...or empty yer wallets!
Simply put if I had time Thursday morning when the video came out. It made my day. Thank you. Comment tonight after the series is done: Okay. I'm rewatching this video to get further in depth with how you could have gotten to your conclusion with the evidence. Your videos give me experience faster than real life gives me opportunities so these are the things I'm picking up on: Camshaft position sensor code has a comment about misfire...okay, that's expected. If an engine isn't known where it's at it can cause misfires. (Speaking of usual misfires associated with camshaft sensor trouble.) I'd expect a P0300 to come with it ... Misfire codes tend to set faster than any other code in my experience. If this was the primary concern based on the PCM's evidence why in the world wouldn't such a code get set too? My only answer is because firing is happening on time, that's obvious to this good camshaft sensor and the crankshaft sensor...the reference wording in this case with the camshaft code doesn't apply to the situation correctly even in an unspecific way. Further throwing out misfires being the primary concern. While the engine is running wrong, it's generally even. In my ACE prep studies there is a comment about loose timing chains causing a slapping sound....doesn't this sound remind of that, the material is just different? MAF code, not enough air? If I keep your FASTTEC method in mind for a car that won't start and remember to consider timing as a basic reason for an engine running right, then and only then could my mind go where yours did. Thank you for influencing my thinking in the future. Forgive me if these comments were better suited as notes for myself than a public comment.
I have had the same car now for 11 years, do all the maintenance myself, the only special tool that I have encountered being necessary is the spark plug boot puller, the rest can be improvised. Even the timing belt tensioner tool is unnecessary, a c-clip tool works perfectly.
Indeed we feel the same about special tools as you here in europe. They make it just to rip us off. That is for sure. The same goes for modular parts that you cannot just fix, the only way is to replace the whole unit. And that is why as DIY I never own cars newer than 1995 or so :) As always - good to see You again and greetings from Netherlands! Btw hope to see videos from you more often?! ;)
Proof that some dealers have poor excuses for a mechanic. Troubleshooting skills and knowledge on the cars they work on is key requirement to the position. I had a error code related to secondary air pump pressure being shorted. Guess what they wanted to do? Replace all related components related to the secondary air pump system to the tune of $960. I checked the pump and it was fine. Replaced the pressure sensor ($85) and cleared the VW proprietary codes ($30)... Took 1 hour total. Passed emissions.
I just did a t-belt on my friends 2.slow Jetta and it was in similar condition at 180k miles. I definitely recognized that sound right away! Seriously tho, this guy is lucky!! I just found your videos today and have fallen in love with your channel. I too am always a skeptic, especially since my friends are too poor for me to throw parts at their cars without exhausting all other options first!
The camshaft position sensor the other guy replaced is behind the timing belt pulley, which means the guy was working in that same spot and never noticed the belt was missing all those teeth and the tension wasn't set right.
It's always best if you can replace the belt and show that the repair is verified on video. 99% sure you found the issue but you never know until the after repair video shows the viewer the confirmation of diagnosis. I thought it was going to be a sheared crank pulley myself because they can make similar clicking noise. Great job finding the issue quickly and efficiently.
***** Yes if time allowed I would do that but I am leaving out of town soon and have to desperately get this car out of here. Even if there was other damage the diagnosis still holds true and the main thing was the point that changing the CMPS is just lunacy.
***** For the customer yes but for the money no. The fault said cam pos sensor so a position sensor is an easy sell. People these days are actually proud of the fact they know nothing about cars. This makes it easier than ever to rip off a customer.
Andrew Thompson Andrew is correct- the lack of diagnostic capability combined with customer not being car savvy equals huge profit. If customer had OK'd a $3000 camshaft replacement, the shop would have immediately noticed the broken tensioner and stripped belt as part of the process. A whole timing kit for this engine is $150. I don't think for a second they would have said "ohhhh, our bad- your bill is now just $600 for a belt instead of $3K for a camshaft".
Schrodingers Box that's what i tell my friends and i believe in, you should be honest with the customer because if you'll tell the truth, you are getting a satisfied and regular customer
daverd2003 I guess that when changing the camshaft they would replace belt (and whatever it drives) as a matter of course. So you are right. You can waste peoples money and still be considered a good mechanic. People need to learn about cars or they will be ripped off BIG TIME.
Bryan Lozano Thanks, but you shouldn't feel good on a correct guess any more than an incorrect guess. From a logical perspective, the outcome of a guess being either correct or incorrect has equal significance-- which is none at all.
Schrodingers Box keep up the good work I've learned a lot from your videos, diagnose diagnose diagnose.... hate when "mechanics" throw parts at a car hoping it'll fix it.
When a shop say you need something and they replace it. If you still have the problem. You need not pay because they did not fix the problem. In my case. I bought a 2004 Golf 4 months ago. The a/c does not work. The dealer said there was a wiring problem and they needed $1300 to find the problem. After finding the problem. They wanted $1700 more to fix the problem. I told them I was coming to pickup my car.
My girlfriend has a 2002 beetle 2.0 with 53k miles and it has a coolant temperature sensor code and misfires on all but one cylinder, plus a random misfire code. The mechanic said head gasket but I'm hoping it's just the sensor. There is plenty of air coming out of the crankcase when I open the oil cap. I would assume piston rings but I guess it could be a bad gasket letting combustion gasses into the oil passages? I'm probably overthinking it but I guess I'll find out once I check more things.
VW and Audi valves do not open past the cylinder head bowl (combustion chamber), that is why you don't see bent valves occurring during belt catastrophe. All cars have some special tool, to define special tool is a tool that any individual doesn't have. Finding noise is easy but first you need a special tool called a stethoscope or something similar that's non electric powered, RF signals interfere with the mic. It's easier to use than removing parts unnecessarily and putting unrelated parts back. Unless the head and the block were milled heavily, this will be that instance you'll see bent valves.
Schrodingers Box This is a 2.0L AEG engine found in most MK4's and MK3's, with just the timing belt off you can turn the crankshaft 360* without any interference from any valves opened in any of the chambers, the same thing happens when you turn the camshaft even with a 12.5:1 CR. You can turn both the crankshaft and the camshaft in opposite direction and nothing happens as in valve head butting. Probably the cause was improper belt tension, there is an arrow/pointer behind the tensioner pulley. With an inspection mirror you must line up the pointer with a notch using your 2 pin adjustment tool. Once belt is in correct tension you'll notice some slack on the leading end of the belt mistaking it as too loose. The trailing end of the belt is where all tension is applied. Timing marks are found on the upper rear toothed belt guard, an arrow and O.T. is it's mark. Flywheel mark is an oblong shaped lined up at lower edge of sight window for AT, MT will be lined up in the middle of sight window. Hope that helps.
Kinda knew what the noise was from the getgo, but I tell ya, that is still a terrifying noise to hear! I kinda cringed when I first heard it... A weird thing about non-O2 sensor codes; a majority of the time, if the PCM is throwing a code, the only way it could possibly know to set the code in the first place is if the sensor is working correctly. Understanding how each sensor works, as well as circuit design, can help determine pretty quickly whether or not the sensor is potentially bad. It's not a concept I normally bring up, but I think this channel is advanced enough to understand the underlying complexities of it. :)
rhkips Absolutely 100% correct as usual, Kips. A code that mentions a sensor by name is often indication the sensor is working rather than at fault. I call it "blah blah blah oxygen sensor blah blah blah... guess I have to change the oxygen sensor". The "blah blah blah" is actually telling you the sensor is working and reporting a condition if you understand it.
hello, Matt I want to know from those two thumps down people if there is better way to diagnose this car so we can learn more any way a big thanks to you for sharing your knowledge and the way you approach and solve the problem well done my friend.
j georges Lol, one of them is probably the mechanic that saw the car before me hahahaha! Actually I know exactly who some of these thumbs downers are- but I know they watch all my videos and I get paid for that, so I don't ban them lol. There are several haters out there- mostly people who don't like being showed up by an amateur. The other (and more common thing actually) is a lot of people don't understand the rational, diagnostic approach. They don't want to understand the thinking and theory- they just want to see what it looks like to take parts off a car that they will never actually ever do themselves. The funny thing is, either way, less than 1/10 of 1% of the votes for all my videos are negative- so it actually just ends up making them look like more of idiots than they already are.
Schrodingers Box Matt, you calling yourself an amateur LOL, there is mechanics out there with a big fat label in there shirts but in reality they are just parts changers I, learned a lot from watching your channel in short time that will take months if not years to digest so a big thumb up and thank you for all the info you share.
j georges And to you as well- because your attitude is dead on. Indeed it takes months- at the very minimum, months and probably years. It is so rare for someone to recognize that (much less embrace it!) because TH-cam has created an impression where people think they can watch a 3 minute video without leaving their armchair and become experts in fuel injection. I really have to thank you and the few like you J, because it is refreshing to hear from people who "get it" and appreciate what I am trying to do. Trust me, it is much harder than selling out by making 3 minutes parts changing videos. You keep watching and I'll keep producing- fair enough for me.
What is this whistling noise beginning at 0:34 right before you took the microphone? I have this noise and it's driving me crazy. Guys, please help if you have any ideas
Hey Mr... I love your videos keep up the great work.... from my understanding when you remove the valve cover there is another cover that goes over the cam shafts... could that be your broken piece? Also there is the all time audi vw problem where the high pressure fuel pump wears heavily on the cam lobe... my two cents
Jose Sifuentes Indeed a loose fragment of some sort behind the timing cover was highly suspected. As for a high pressure fuel pump wearing out a cam lobe- that honestly makes no sense to me whatsoever off-hand. What is proposed theory behind that?
Audi Volkswagen have direct injection on their vehicles... if you so happen to have this engine.... what we see here at the stealer ship is the highpressure fuel pump runs off a cam lobe and that part becomes heavily worn
being that i have recently purchased a VW, with the VR6 at the 1:00 minute mark of the video i have to pause it and take a wild guess. The Bushings on the rod that is in the intake are shot. =)
Well done Matt. The automotive repair field seems to be so unreliable , either lack of training or lack of trying. The last ASE trained shop was out to lunch on this one. Imagine surgeons with this type of mindset . There are plenty of great techs out there that should be paid as well a surgeon and I imagine there are some surgeons that should be paid like the one that changed the cam sensor :)
Steve Rob Great Point!!! One of my viewers last year (a female no less) said exactly the same thing- what if a surgeon was allowed the same leeway as mechanics in diagnosing a condition. "Welp, it wasn't your spleen... lets try removing your thyroid" lol. The fact is, as you well know, there is NO DIFFERENCE WHATSOEVER in the diagnosis of a car vs the diagnosis of a medical condition vs determining the cause of a disease. The thought process is (well, should be) 100% identical in every way in all of these.
Re the special tools I absolutely hate that!!! I hate going to do a job only to find you have to jimmy rig something together or buy the stupid tool that you will use once! I am in total support that we need to stop this! Rant over great video as always.
That engine is an interference engine man he was lucky. Many problems with water pumps on them BUT not having the belt changed at the proper time is crazy.
Was there any valve damage? I have an 04 Golf, they are *supposed* to be a non interference engine (this Jetta appears to also be a Mark 4 like mine) and my water pump impeller (plastic) exploded, pump seized, ripped a bunch of teeth off my timing belt, and I ended up with 5 damaged valves. I was shocked. Machined the head and replaced all the valves, polished up the pistons, new timing belt and new water pump with a METAL impeller, and now besides some obnoxiously loud valve noise she's all good again.
the problem with pro shops are they are pushed to do a job quickly as possible. the mechanics arent really allowed to "dick around" with trouble shooting the shop owners just care about the bottom line
Being from germany I have to say that I don't like special tools either, but all cars build after 1995 have some things on them which need speacial tools. At least the European cars. Is it really true that US cars from 2005 can be repared without special tools? Secondly the jetta has to be an interference engine. My 1989 AUDI 80 B3 which has a VW engine is an interference engine and I'm almost 100% sure that VW never build a non interference engine after the AUDI 80 B3. Does the car really did not take any damage? To me that sounds impossible. How was it possible for the camshaft to continue turning with so many teeth missing? Only thing I can think of is that the number of teeth missing is smaller than the groves on the camshaft and crankshaft weals. The owner it definitely one of the luckiest people on planet earth this week. Thanks for the video and keep up the good work. Best regards Ben
I tried reading the comments but theres too many. What was the problem exactly because my 2012 Jetta TDI Premium sounds exactly like this but drives fine. Im in a hurry. Could you clarify for me, thanks.

@Schrodingers Box Heyy Mate, i'm curious. The loan car of mine its a VW Plus 1.9 TDI 90hp... And it started making that noise aswell, the only weird and odd thing is. It only makes that sound when you've driven for 30~ minutes. Did this car with the timing belt tensioner had the same symptoms or did it even make that sound on cold engine?
@@SchrodingersBox Merci for the quick reply mate! I know i shouldnt rule it out, but was hoping for good news, i dont like to have broken loan cars lol. As my own Honda is being repaired.. Do you ever make videos in regardings of Hondas? If so, you're the source of knowledge I want to know :P Good videos!!
I don;t really make videos on specific cars. To me all cars are the same. They all use the same OBD-2 and the same principles of electrical and engine management.
Schrodingers Box i like your diagnostic skills and methods . you make diagnoses simple and step by step and you take your time to cover all possibilities that whey i subscribed to your channel . thanks again and keep the great videos coming .
I just learned the hard way on my 2009 vw city golf 2.0 is Not a clearance engine....In other words it is an Interference engine and has no clearance from valves to piston .My engine for the record is also 8 valves
So I have a 2011 vw jetta 2.0 L s. No real accerleration, engine light on wasn't flashing, is now within 2days of being parked, along with the esp or ecp light was on and now off... Engine way louder.. About 20 miles to town, rather not drive to town, so no computer... Just changed plugs, air filter and ignition coil few months ago.. I'm thinking maybe timing belt? Engine moves in Idel.. Any ideas would be great! Thank you
what data do you have that makes you think it’s a timing belt? What is the data that indicates this? Dod you do cam/crank correlation? what’s the timing advance?
@@SchrodingersBox don't have data, that tells me anything.. About a 30 mile drive to town to get on computer I just didn't want to limp it and make the miss fire worse.. Anyway, I changed plugs again, and now I found that plug wire #2 needs to be replaced.. That's my next step. Have appointment next week to get recalls fixed🤦🤷 thanks for your opinion on my question.
whoa i don’t get it- why would you buy a coil pack?? What evidence is there that this is the problem?? Save your money. Get data and analyze it to find the cause. don’t guess.
03 vw golf 2.0 automatic. Making a continuous ring under the hood. High pitched noise only goes about thirty seconds but i can't find nothing about it seems like. I'm new to vws and well cars in general lol.
not a severely bad idea to replace the tensioner and sensor(s), but don't know how or why they didnt diagnose or at least check the rest of that mechanical chain to be sure everything good. to me i see so many people just replace sensors thinking that'll be it and move on.
i think i prefer timing chains vs. timing belts. i have actually never had a chain fail and the only reason i have ever replaced one was if i was in there anyways for some other reason and did it as a preventive. chains are stronger then belts and do not generally require tensioners. also belts age and dry out you can have a timing chain that is 20+ years old and still fine because its steel and not rubber. im not even sure why the use timing belts, i think they suck in my opinion. yes chains can wear out but that takes many, many miles (as many as 200k+ miles) and they usually stretch and dont break.
+andrew donohue Agreed! Timing chain fan right here- plus being a high performance kinda guy, nothing beats a chain when running 400+HP I can assure you!
for real stupidity how about an interference engine with a timing belt. has to be one of dumbest things going, but i believe there are quite a few Japanese cars like that. belt lets go and BANG, was that a valve hitting a piston , that engine just became a paper weight in seconds.
I generally agree that chains are preferable to belts, but they can have some drawbacks too. I had a Mercedes with a M104 engine before, with a timing chain that was leaking oil from the cover. It was common to have a leak at that cover as the design had two intersecting planes of sealing surfaces. Belts don't need lubrication so the issue is avoided altogether.
yeah that's possible how bad of a leak? a small leak is an annoyance and wont leave you stranded. i also think that if you do have a leak that typically its a small leak and as long as you watch your oil level its not much of a concern . a belt will leave require replacement AND it can damage the engine very seriously if it fails on an interference engine. if the timing belt fails on and interference engine, the crankshaft will continue to rotate and the cam will stop. valves meet piston BANG major damage and a possible completely trashed engine.
Hey Matt, that was an efficient 10-minute diagnosis! Wow I'm really surprised the engine is still running with all those teeth missing on the belt. As for the P0102 MAF code, those VW MAF sensors are prone to failing for no reason, often resulting in a start-stall as the signal to the PCM will be lower than it should be for a certain airflow. Just diagnosed one a few weeks ago...quick test is unplug the MAF and if the car runs fine then you're done lol. The P0340 looks like a circuit fault...wonder if the loose belt hit the sensor and messed it up? Wouldn't be surprised if the new one is toast too haha. You need a scope ASAP to show us some sensor signals :) Horray for parts changers!
motoYam82 Yeah the fact check engine light only came on after the noise started leads me to believe the MAF is related to the timing. If I had time, I would have checked the CMPS signal actually. Note I said if I had time... not "if I had a scope"... hmmmmmmm...... And my next video will be on MAF diagnosis.... hmmmmmmm.......
I have a 2019 VW Jetta and all of a sudden I heard a fluttering when I accelerate. I brought it in, and they said they had to order a Torx screw and some bolts, that I should not be driving it like that; so I have a loaner and will pick it up Thursday. I didn't know what to think, it only has 28,800 miles, and it's a lease. I extended it one year; in October I am going to get a new car. Whaddayathink?
Owner is lucky, timing failure can blow those engines apart! Good vid. I like to watch and see how other people go about things. Can pick up even the smallest things which helps
I really enjoy every one of your videos you make, Schrodingers. I've currently just finished my Level 1 Light Vehicle Maintanance and Repair at college and I have to say, without sounding too much like I'm kissing your arse here, your videos have helped me a lot with the practical side of my course - so thank-you so much!
As a trained glorified parts changer (aka us army mechanic) I have always tried to find a better way to do this kind of work. I must tell you your videos have given me great knowledge and ability to do more than change parts for a diagnosis. I love watching your videos because everyone of them is like an episode of house. Keep up the great work and I'm proud to be one of the 2%
casey fisher ROTF!!! One of my customers calls me "House M.D. for cars" lol!!!
I have viewed this video 2 or 3 times just to make sure I heard all of your snide remarks. You honestly need to write a book. I would hate to be a mechanic who had a car before you looked at it...I would be so depressed. I always make it a point to watch your videos, not only for the excellent content, but the humor alone is worth the price of admission. Keep it up, sir.
Ha, yeah hopefully I step up their game knowing I'll call them out!!
98%er's that think inside the boxwrench step out and use the open end (17mm) as the special tensioner release tool lol. Do love the videos, watch them all. Follow-up on setting timing belt tensioner was very timely and useful last weekend on own jetta. Thanks!
😂😂 yeah the pliers on the belt tensioner scene was painful to watch and hear😂 i aint no mechanic but the Bentley manual tells you to use a open ended wrench
You make me feel like I'm in the garage helping you diagnose vehicles.......lol. COOL CHANNEL BROTHER.
My car is making that same exact noise right now. I have been freaking out thank you, And yes the car is running perfectly fine too
Did yours fix
Great video! I had a feeling it was timing chain/belt related. I have to admit I used to be part of that 98% but every since your fuel trim videos my life has been changed
Bennie Morgan We all start off as 98%ers actually. A few recognize that and change, but Some are too lazy to change and most by far don't even realize they are the 98%!!
Whats 98%ers?
Once again I would love to give a shout out to all the armchair mechanics who thumbs down the video as soon as it's released and yet they still watch the whole thing, learn stuff they could never do themselves, and despite watching all my videos they still couldn't diagnose a diaper rash on a baby with sandpaper in its crack.
Just sayin....
As for the 2%ers- a big hello and thanks for your support!!
@Scharodingers Box Lmao This guy!
Schrodingers Box Nicely said, Matt. Don't worry about the boofheads giving you a thumb down that will just result in more of your regulars showing their appreciation and giving you a big fat thumbs up!
Keep up the good work, mate. :-)
Schrodingers Box Hi Matt, in cars VW is possible diagnostic this problem with VAG-COM, look the parametre "Angle Sincr"
In the engines diesel if "Angle Sincr" is more 4º the difference between CKP and CMP the engine don´t start.
When that happens in VAG COM can see for example: Camshaft Position Sensor (G40): Signal Out of Range.
Greetings from Spain. =)
You laugh. Theres some moms i know that cant figure why a baby is crying...but i dont want to use powder...they could inhale it lol. Then i hand em a tube of ass cream....problem solved...im an idiot. Lol
Schrodingers Box Take it easy, if you let that stuff get under your skin, you'll never survive TH-cam, stress kills. People are idiots and everyone knows it.
Matt great lesson to all the people out here in you tube land that think all there is to diagnosing a modern vehicles is plugin in your whatever and getting a code(s) are sorely misinformed or downright ignorant. Verify,confirm and validate.Thanks again.
Daniel Wells Thanks Daniel. BTW "wells" is perfect last name for a diagnostic mechanic lol. Any relation to the company?
Yeah TH-cam blows- I actually decided to look at the market for videos on the timing belt change- NONE showed the correct procedure for adjusting tension and in fact the most watched video on the subject of all (almost 300K views) didn't even mention tensioning- in fact the hack put the belt right back on the same timing components with no tensioning adjustment!!!
I feel responsible to now make a video of the tension adjustment just so TH-cam will have a resource for this engine.
Schrodingers Box TH-cam blows? Mr. Box I love your videos. They are spot on for someone who is not a paid tech. I hope you continue to contribute.
Great videos you have here man! I gotta say, you and Eric the car guy are the only two car channels I watch now! i'm desperately trying to emerge from being a parts changer and your videos are helping me a lot!
+coolbluelights Yeah ETCG is a great guy and all but he's really geared more for beginners. You won't find me changing oil or a radiator here lol. I actually stopped watching him years ago. He's a great guy though but I just get bored dizzy watching wrenches spin and spin and spin and spin...
Yep i've kind of graduated from his class now haha
coolbluelights You should also check out my friend Paul Danner's channel channel name is scannerdanner. He's even a major step up from what I do. Check his channel out!
oh, I have seen some of his vids, he uses those high end scan tools that cost more than I paid for my car haha
coolbluelights ROTF!!! Yeah I know... but the concepts are valuable lol. Yeah I am kind a poor man's version of him lol
No special tool needed for the serpentine belt tensioner. An open end wrench (17mm?) will fit on the same tab where you put the vice grip.
On my VW Eurovan, the "special tool" for the same function is an 8mm bolt.
Yeah i know, as soon as people from murica or canada (or where ever) see an euro car. They freak out. Do some reading. I know, alot of german cars (like my passat -98 v6) needs special tools and all that. But that's usally only for the dealership. They wanna make some money maybe? But you REALLY don't need em. 9/10 you can get by them.
And in this case, NO there are no special tool. It's 8mm allen head bolt so you can turn it? I can't remember but there are like a regular 10 mm bolt that you can remove it with...
I'm looking for the egr valve or combi valve on my 99' vw golf gti and cant seem to find it or figure it out anywhere else. Hoping you might be able to help me out?
Half the fun of owning my Golf is making the "special" tools in my kitchen and giving the finger to VW. ;)
Great video as ever Matt o/
Bob Moore Yes I agree with you- there is definitely a satisfaction to designing your own work-arounds for special tools- especially ones that cost a lot. I have a whole collection of specialty tools I've made over the years, but the difference is most of them will apply to many, many makes and models. To make a specialty tool for a single model that I may never see again is just not possible because nowadays I have other cars waiting in the queue and I can't spend 2 hours making a tool to replace a drivebelt.
Hi,Just like to say that I think the reason for strange shaped and odd tools here in Europe is so we are deterred from doing any work to our cars and take them to the dealership and the car maker can squeeze you for even more cash.Thanks for sharing my friend 👍🏻
Thanks for sharing ,,,, thought I was caught up seeing most of your videos but it seems youtube knows better sending me all the ones I missed from years ago but just as good as a new one , timeless !
You ain't a true VW owner without a check engine light.
No special tool required for the removal of the serpentine belt. 16mm wrench to slacken off the tensioner. There is also a hole in the tensioner that you can insert a 4mm drill / pin to lock it in the loose position.
As always, a Great video. As for those that give you the thumbs down, you need to feel sorry for them to some extent. What most people don't realize, is that -
Stupidity is a real illness, and there is no known cure for it.
Thank you for all your efforts at making these videos, so we can all benefit from your knowledge and the " No Nonsense Approach" that you use to come to the right conclusion, in the fastest time possible.
Best regards, Joe
Well stated my friend! Much appreciated!
How did the shop not catch this?! You have to pull the timing belt and cam gear to get to the cam pos sensor!!
Exactly what I was thinking.
They are the ones that damaged it. Slapped it back on and said get it the hell out of here.
Very lucky owner... should be interference fit, although I too have seen some that did not bend valves.
***** Ah I totally forgot- you work on VW's all the time on your channel don't you? Yeah I had a lot of trouble researching for sure if it is interference or not. But is sounds very obvious no valve damage was done.
***** If you decide to comment on the new videos I hope you let me know that you did, considering what looks like is your primary experience: VW.
That's what I thought as well
Cool to See Thomas here, excellent VW mechanic!
man, i joined you recently and now i have alot of respect for you, you are indeed a professional. please continue making more videos and also kindly recommend me a cheap scan tool which can make diagnostics a little easier
EngrChillaX I actually used an Innova model- I think a 9430 if I remember. It had all the features you need for like $290
Schrodingers Box thanks
***** It is self contained, however connecting to a laptop will allow you a bit better analysis (e.g. generate graphs, etc). I also own an old Mac TaskMaster that I use in the field sometimes. You can find them on Ebay a lot. It's nothing short of excellent for a scantool under $400.
Thanks a lot for your info-clip and yes, we do have the same two-liter engine in a Jetta and yes,
it is trying to tell me something (=being noisy) and yes, I'll check the belt you've shown!
man I think even A 98%'er such as myself could have diagnosed that! Good job Matt. I can not believe shops can miss something like this and charge for giving the totally wrong diagnosis.
Great video. Not surprised that the previous "professional" shop never figured it out. Goes to show....most issues can be pretty obvious with a little unbolting yourself. Also, it pays to know a guy who knows his way around an engine. I havent taken my car to a "pro" shop in years. What I can't do myself....I take to my Mechanic Guy...who isn't a licensed mechanic. (BTW, I own a 2011 Jetta, 2.5L) cheers!
there is a 3/8 fitting on the end of the serpentine tensioner on VW/Audi ...just enough space to get a rachet on it ...love the videos
Great video and nice save! I think the 'special tool' you're alluding too for the tensioner is commonly known as a 14mm spanner.
Its a 16 mm :)
Apologies! That makes it even more special! Pesky VW ;)
Timing belt tensioner wrench vw = fleabay
Don't worry Matt, it drives us crazy too, european aspiring to be 2%er here. Even worse than the special tools needed is the lack of physical workspace that occurs in the engine bay of european cars as opposed to north american ones. Granted, I don't like 98% (I chose a random number here :)) of american cars (although I must admit the Trans Am is a beauty), but they are surely easier to work on.
In Europe we love to overcomplicate things and it applies to many real life situations as well, unfortunately.
As a side note, it's now about 4 months that I'm binging on your videos on YT and SBQM and the things I'm learning are just amazing. Your way of explaining never gets tiring and that combined with a sour, harsh sarcasm makes it for a really entertaining time.
I can't help but crack a laugh when you get aggravated by the inevitable plugs+wires or sensor swap (I used to do it too when I didn't have a clue). It's just hilarious! Keep up the good work man!
Great video. You really saved that customer a lot of money.
White Tiger Thanks Tiger. I actually charged him a total of just $250 for everything. Not bad for a timing belt, I think. And sure as hell better than a $3000 camshaft!!
This man is a genius.
I don't understand how Scotty Kilmer has 338k subscribers and you only have 22k. As a full time truck mechanic there's plenty of thingS I don't understand on automobiles. But I can tell you right now I learn waaaaay more from you than Scotty, "the Emmy award winning mechanic"
asavage1576 Thanks but I know exactly why- its because Scotty caters to the masses. Most people by far will lose attention in 3 minutes. They like the idea that they can become an "expert" by watching just a 3 minute video and never getting their hands dirty. Then they take their expertise to the chat room and forums and spread the disease of ignorance right from their armchair.
Time to change the water pump also, since you're in there.
The requirement for specialist tools for European cars is entirely deliberate, manufacturers don't want us tinkering with their cars when they have a dealer network that will happily charge us £100 per hour to carry out the work.
It's actually a very weak act. Most of the time technicians just improvise like in this video because it is too much effort to leave the job to find the silly tool. I like all this nonsense because it helps to make European cars very cheap to buy used.
You can find ways around that, I have used a socket with a extension to pull that belt cover back, you just gotta think out of the box. ;)
you can also use a nail or something similar to pin that tensioner in place to make belt installation easier
That's a VW Mk4. Ask me how I know! I had that exact same sound on a 2002 Vw Golf, started about ten miles before the car wouldn't go anymore because the timing belt lost too many teeth.
As it turns out, the 2.0 is sometimes listed as interference, sometimes not. Valve damage can occur.
Anyway, thanks! I've been trying to figure out what made the teeth come off like that, and a loose tensioner makes sense. Wish me luck putting it back together without needing to replace the head.
Yeah good luck- I too have seen it listed both in interference and non-interference so I am not even sure! Either way, hopefully the valves are still straight!
what happened to me i did not change the timing belt or forgot to !! im original owner of a 02 vw golf 2.0 gl bought it with 16 miles on the OD !! im a bad owner !! BUT the timing belt did not break on its own until 159k miles !!! thats a long life for a timing belt !!! sux i had to replace all the exhaust valves !!! cost me 1200 dollars !! live and learn !!
Thank you you are a smart man my VW bug was making the same noise for about two days I came home from work to shut it off had to get back out to go to the grocery store and at start up it went capoop smoke coming from the engine..
A bit worrying now, i have something that sound almost identical to this on my Passat 2.0TDI so now i'll have to check the belt just to be sure.
He should be so ever greatful for you finding it before it broke! WOW!
Excellent video! Joy's husband here. Small time repair guy. Yes; germans make a lovely engine. (Got a BMW 325xi with 300k. Motor is like NEW. Obviously; well maintained!) AGREE completely: the special tool thing is wildly annoying. Diagnostic difficulty also. Yeah; i got a 99 Passat with that HORRENDOUS "rattling" in the top of the engine. Gotta be like yers; tensioner out to lunch. Some other videos indicate a 'chain' in the rear of the engine. (another brilliant german anomaly. vis a vis: the HORRIBLE german V6 in the last model Ford Explorer. Goofed up all the time due to lack of oil changes.) Great engines...BUT; you better do the maintenance dawg...or empty yer wallets!
Ik ben hier voor de intro. Subliem.
Simply put if I had time Thursday morning when the video came out. It made my day. Thank you.
Comment tonight after the series is done: Okay. I'm rewatching this video to get further in depth with how you could have gotten to your conclusion with the evidence.
Your videos give me experience faster than real life gives me opportunities so these are the things I'm picking up on:
Camshaft position sensor code has a comment about misfire...okay, that's expected. If an engine isn't known where it's at it can cause misfires. (Speaking of usual misfires associated with camshaft sensor trouble.)
I'd expect a P0300 to come with it ...
Misfire codes tend to set faster than any other code in my experience. If this was the primary concern based on the PCM's evidence why in the world wouldn't such a code get set too? My only answer is because firing is happening on time, that's obvious to this good camshaft sensor and the crankshaft sensor...the reference wording in this case with the camshaft code doesn't apply to the situation correctly even in an unspecific way.
Further throwing out misfires being the primary concern. While the engine is running wrong, it's generally even.
In my ACE prep studies there is a comment about loose timing chains causing a slapping sound....doesn't this sound remind of that, the material is just different?
MAF code, not enough air?
If I keep your FASTTEC method in mind for a car that won't start and remember to consider timing as a basic reason for an engine running right, then and only then could my mind go where yours did.
Thank you for influencing my thinking in the future.
Forgive me if these comments were better suited as notes for myself than a public comment.
Nice job setting the shop's sloppy diagnosis straight.
+Kevin Thanks- you would be amazed how often Ithis happens... every single weekend in fact.
I have had the same car now for 11 years, do all the maintenance myself, the only special tool that I have encountered being necessary is the spark plug boot puller, the rest can be improvised. Even the timing belt tensioner tool is unnecessary, a c-clip tool works perfectly.
Indeed we feel the same about special tools as you here in europe.
They make it just to rip us off. That is for sure. The same goes for modular parts that you cannot just fix, the only way is to replace the whole unit.
And that is why as DIY I never own cars newer than 1995 or so :)
As always - good to see You again and greetings from Netherlands!
Btw hope to see videos from you more often?! ;)
Proof that some dealers have poor excuses for a mechanic. Troubleshooting skills and knowledge on the cars they work on is key requirement to the position. I had a error code related to secondary air pump pressure being shorted. Guess what they wanted to do? Replace all related components related to the secondary air pump system to the tune of $960. I checked the pump and it was fine. Replaced the pressure sensor ($85) and cleared the VW proprietary codes ($30)... Took 1 hour total. Passed emissions.
Beautiful place to work. All kind of things correctly organized!
Yes when you only have a two car home garage you do need to be organized to maximize space!!!
I undestand because I have a one car home garage! Check mi channel I have some videos about mechanic!
I gave you a like specifically for your shout out to companies that force the use of unnecessary special tools 👍
Thanks for that!
I just did a t-belt on my friends 2.slow Jetta and it was in similar condition at 180k miles. I definitely recognized that sound right away!
Seriously tho, this guy is lucky!!
I just found your videos today and have fallen in love with your channel. I too am always a skeptic, especially since my friends are too poor for me to throw parts at their cars without exhausting all other options first!
The camshaft position sensor the other guy replaced is behind the timing belt pulley, which means the guy was working in that same spot and never noticed the belt was missing all those teeth and the tension wasn't set right.
Excellent troubleshooting technique, I learned a lot - thanks!
You just got it in time . Good video
Wow your customer was extremely lucky and had good reason to sweat over this noise!
Great work!
PS: it is an interference engine... Cheers!
It's always best if you can replace the belt and show that the repair is verified on video. 99% sure you found the issue but you never know until the after repair video shows the viewer the confirmation of diagnosis. I thought it was going to be a sheared crank pulley myself because they can make similar clicking noise. Great job finding the issue quickly and efficiently.
***** Yes if time allowed I would do that but I am leaving out of town soon and have to desperately get this car out of here. Even if there was other damage the diagnosis still holds true and the main thing was the point that changing the CMPS is just lunacy.
Schrodingers Box Without proper diagnostics and guessing everything is lunacy. ;)
***** For the customer yes but for the money no. The fault said cam pos sensor so a position sensor is an easy sell. People these days are actually proud of the fact they know nothing about cars. This makes it easier than ever to rip off a customer.
Andrew Thompson Andrew is correct- the lack of diagnostic capability combined with customer not being car savvy equals huge profit. If customer had OK'd a $3000 camshaft replacement, the shop would have immediately noticed the broken tensioner and stripped belt as part of the process. A whole timing kit for this engine is $150. I don't think for a second they would have said "ohhhh, our bad- your bill is now just $600 for a belt instead of $3K for a camshaft".
Schrodingers Box that's what i tell my friends and i believe in, you should be honest with the customer because if you'll tell the truth, you are getting a satisfied and regular customer
also worth noting that a shop would put a new belt and tensioner on stating that during disassembly they noticed that was worn as well
daverd2003 I guess that when changing the camshaft they would replace belt (and whatever it drives) as a matter of course. So you are right. You can waste peoples money and still be considered a good mechanic. People need to learn about cars or they will be ripped off BIG TIME.
Nope....timing belt...another great video. I love these.
i love your videos.
I'm assuming by changing the tensioner it fixed the noise?
I guessed timing belt. I feel good :)
Love the videos man!
Bryan Lozano Thanks, but you shouldn't feel good on a correct guess any more than an incorrect guess. From a logical perspective, the outcome of a guess being either correct or incorrect has equal significance-- which is none at all.
Understood and agreed. Again, love the channel man. Thank you
Bryan Lozano A confirmed 2%er!!!!
Excellent video once again....
Antonio Casas I almost didn't film this one thinking it didn't fit with the usual production motif, but I'm glad I did.
Schrodingers Box keep up the good work I've learned a lot from your videos, diagnose diagnose diagnose.... hate when "mechanics" throw parts at a car hoping it'll fix it.
Drives us crazy too, it’s a way of increasing revenue for the main dealers probably, so definitely necessary for them.
When a shop say you need something and they replace it. If you still have the problem. You need not pay because they did not fix the problem.
In my case. I bought a 2004 Golf 4 months ago. The a/c does not work. The dealer said there was a wiring problem and they needed $1300 to find the problem. After finding the problem. They wanted $1700 more to fix the problem. I told them I was coming to pickup my car.
My girlfriend has a 2002 beetle 2.0 with 53k miles and it has a coolant temperature sensor code and misfires on all but one cylinder, plus a random misfire code. The mechanic said head gasket but I'm hoping it's just the sensor. There is plenty of air coming out of the crankcase when I open the oil cap. I would assume piston rings but I guess it could be a bad gasket letting combustion gasses into the oil passages? I'm probably overthinking it but I guess I'll find out once I check more things.
VW and Audi valves do not open past the cylinder head bowl (combustion chamber), that is why you don't see bent valves occurring during belt catastrophe. All cars have some special tool, to define special tool is a tool that any individual doesn't have. Finding noise is easy but first you need a special tool called a stethoscope or something similar that's non electric powered, RF signals interfere with the mic. It's easier to use than removing parts unnecessarily and putting unrelated parts back. Unless the head and the block were milled heavily, this will be that instance you'll see bent valves.
yogegoy Beg to differ but ALL sources clearly indicate this engine is an interference design.
Schrodingers Box This is a 2.0L AEG engine found in most MK4's and MK3's, with just the timing belt off you can turn the crankshaft 360* without any interference from any valves opened in any of the chambers, the same thing happens when you turn the camshaft even with a 12.5:1 CR. You can turn both the crankshaft and the camshaft in opposite direction and nothing happens as in valve head butting.
Probably the cause was improper belt tension, there is an arrow/pointer behind the tensioner pulley. With an inspection mirror you must line up the pointer with a notch using your 2 pin adjustment tool. Once belt is in correct tension you'll notice some slack on the leading end of the belt mistaking it as too loose. The trailing end of the belt is where all tension is applied. Timing marks are found on the upper rear toothed belt guard, an arrow and O.T. is it's mark. Flywheel mark is an oblong shaped lined up at lower edge of sight window for AT, MT will be lined up in the middle of sight window. Hope that helps.
yogegoy Still gotta disagree with you- when are at maximum lift on any cam lobe I am quite confident you would have interference in the condition.
Kinda knew what the noise was from the getgo, but I tell ya, that is still a terrifying noise to hear! I kinda cringed when I first heard it...
A weird thing about non-O2 sensor codes; a majority of the time, if the PCM is throwing a code, the only way it could possibly know to set the code in the first place is if the sensor is working correctly. Understanding how each sensor works, as well as circuit design, can help determine pretty quickly whether or not the sensor is potentially bad. It's not a concept I normally bring up, but I think this channel is advanced enough to understand the underlying complexities of it. :)
rhkips Absolutely 100% correct as usual, Kips. A code that mentions a sensor by name is often indication the sensor is working rather than at fault.
I call it "blah blah blah oxygen sensor blah blah blah... guess I have to change the oxygen sensor". The "blah blah blah" is actually telling you the sensor is working and reporting a condition if you understand it.
hello, Matt I want to know from those two thumps down people if there is better way to diagnose this car so we can learn more any way a big thanks to you for sharing your knowledge and the way you approach and solve the problem well done my friend.
j georges Lol, one of them is probably the mechanic that saw the car before me hahahaha! Actually I know exactly who some of these thumbs downers are- but I know they watch all my videos and I get paid for that, so I don't ban them lol. There are several haters out there- mostly people who don't like being showed up by an amateur. The other (and more common thing actually) is a lot of people don't understand the rational, diagnostic approach. They don't want to understand the thinking and theory- they just want to see what it looks like to take parts off a car that they will never actually ever do themselves.
The funny thing is, either way, less than 1/10 of 1% of the votes for all my videos are negative- so it actually just ends up making them look like more of idiots than they already are.
Schrodingers Box Matt, you calling yourself an amateur LOL, there is mechanics out there with a big fat label in there shirts but in reality they are just parts changers I, learned a lot from watching your channel in short time that will take months if not years to digest so a big thumb up and thank you for all the info you share.
j georges And to you as well- because your attitude is dead on. Indeed it takes months- at the very minimum, months and probably years. It is so rare for someone to recognize that (much less embrace it!) because TH-cam has created an impression where people think they can watch a 3 minute video without leaving their armchair and become experts in fuel injection.
I really have to thank you and the few like you J, because it is refreshing to hear from people who "get it" and appreciate what I am trying to do. Trust me, it is much harder than selling out by making 3 minutes parts changing videos.
You keep watching and I'll keep producing- fair enough for me.
good diagnosis. keep up the good work
an open end spanner is used to release belt tension, 17mm i think
Great explanation!
What is this whistling noise beginning at 0:34 right before you took the microphone? I have this noise and it's driving me crazy. Guys, please help if you have any ideas
Hey Mr... I love your videos keep up the great work.... from my understanding when you remove the valve cover there is another cover that goes over the cam shafts... could that be your broken piece? Also there is the all time audi vw problem where the high pressure fuel pump wears heavily on the cam lobe... my two cents
Jose Sifuentes Indeed a loose fragment of some sort behind the timing cover was highly suspected. As for a high pressure fuel pump wearing out a cam lobe- that honestly makes no sense to me whatsoever off-hand. What is proposed theory behind that?
Audi Volkswagen have direct injection on their vehicles... if you so happen to have this engine.... what we see here at the stealer ship is the highpressure fuel pump runs off a cam lobe and that part becomes heavily worn
Ohhhhhhh- that makes sense! Yeah I am not versed in direct injection. I will have to research that but your explanation seems reasonable.
being that i have recently purchased a VW, with the VR6 at the 1:00 minute mark of the video i have to pause it and take a wild guess. The Bushings on the rod that is in the intake are shot. =)
Rhage73 keep in mind, that means i will start by looking there. don't mean i would be changing anything
Rhage73 oh crap, the intake is not the same as mine. well wasn't a bad ninja guess as that is super common on the VR6
Well done Matt. The automotive repair field seems to be so unreliable , either lack of training or lack of trying. The last ASE trained shop was out to lunch on this one. Imagine surgeons with this type of mindset . There are plenty of great techs out there that should be paid as well a surgeon and I imagine there are some surgeons that should be paid like the one that changed the cam sensor :)
Steve Rob Great Point!!! One of my viewers last year (a female no less) said exactly the same thing- what if a surgeon was allowed the same leeway as mechanics in diagnosing a condition. "Welp, it wasn't your spleen... lets try removing your thyroid" lol.
The fact is, as you well know, there is NO DIFFERENCE WHATSOEVER in the diagnosis of a car vs the diagnosis of a medical condition vs determining the cause of a disease. The thought process is (well, should be) 100% identical in every way in all of these.
Nice diagnosis Matt, and very lame approach of the previous shop. Lucky owner that no valves were bent...
gianfrancoa Yes I had to do a leakdown test to confirm the valves are OK
Re the special tools I absolutely hate that!!! I hate going to do a job only to find you have to jimmy rig something together or buy the stupid tool that you will use once! I am in total support that we need to stop this! Rant over great video as always.
That engine is an interference engine man he was lucky. Many problems with water pumps on them BUT not having the belt changed at the proper time is crazy.
I agree with Rhage73. That engine seems awfully loose (mounts)..........unless I missed something.
Right. VW's have crappy engine mounts. I always look at the subframe bolts too. (loosen up. break. etc.)
Great video!!!
Was there any valve damage? I have an 04 Golf, they are *supposed* to be a non interference engine (this Jetta appears to also be a Mark 4 like mine) and my water pump impeller (plastic) exploded, pump seized, ripped a bunch of teeth off my timing belt, and I ended up with 5 damaged valves. I was shocked. Machined the head and replaced all the valves, polished up the pistons, new timing belt and new water pump with a METAL impeller, and now besides some obnoxiously loud valve noise she's all good again.
No valve damage but good thought!!!
the problem with pro shops are they are pushed to do a job quickly as possible. the mechanics arent really allowed to "dick around" with trouble shooting the shop owners just care about the bottom line
Being from germany I have to say that I don't like special tools either, but all cars build after 1995 have some things on them which need speacial tools. At least the European cars. Is it really true that US cars from 2005 can be repared without special tools?
Secondly the jetta has to be an interference engine. My 1989 AUDI 80 B3 which has a VW engine is an interference engine and I'm almost 100% sure that VW never build a non interference engine after the AUDI 80 B3.
Does the car really did not take any damage? To me that sounds impossible. How was it possible for the camshaft to continue turning with so many teeth missing? Only thing I can think of is that the number of teeth missing is smaller than the groves on the camshaft and crankshaft weals.
The owner it definitely one of the luckiest people on planet earth this week.
Thanks for the video and keep up the good work.
Best regards
Ben
That is in fact a interference engine, owner got off EXTREMELY lucky. Good thing he didn't just ignore the problem.
I tried reading the comments but theres too many. What was the problem exactly because my 2012 Jetta TDI Premium sounds exactly like this but drives fine. Im in a hurry. Could you clarify for me, thanks.
what is that whine sound on startup? I've noticed that a lot of golfs/jettas have done that...
Re comment about special tools - it drives us crazy over in the UK too!
VW & Ford Car Maintenance Servicing Tips this isn’t by accident with VW it’s well known fact the most of the dealers make a large part of their money is the servicing of the vehicle not so much the sale ............. this is where these CUNTS .... sorry my bad i try not to use their actual name AS ITS WELL KNOWN THAT IT COSTS U $1000 bucks every time you say it VW has excelled in this area with their close out arrogant deliberate miss information you must bring it to us complete close out of any useful information attaining to the servicing of their vehicles and of course there’s that other chestnut every think you fucken touch on these things you do need a special fucking tool almost every time........ this is all not an accident BUT BY DESIGN not in 26 odd years of self maintenance motor cycle/ cars / trucks have U ever encountered such a stonewalling of information maybe with the exception of brown and Hurley and Kenworth trucks here in Australia ...... vw are great WHEN THEY ARE GOING but there is no such thing as a second-hand vaults wagon appreciation society so don’t bother looking ..... my years of fiddle fucken around have taught me even unskilled U will nearly always do and complete any undertakings with more divergence care thoroughness than anybody you ever pay to work on your vehicle + the outrageous $$$$ U give em for the privilege...... unless you’re a complete fucktard tosser of course plenty of dem ...... with these shit boxes i cannot Emphasise on checking your information and re-checking your information as credible information is Without a doubt kept From you by DESIGN.......... ..... 2 words ( DSG /megaTronic’s )...

Thank god for ebay vw tools
Malach211 first tool needed extensive scan tool
Excellent Hoss!
@Schrodingers Box
Heyy Mate, i'm curious. The loan car of mine its a VW Plus 1.9 TDI 90hp... And it started making that noise aswell, the only weird and odd thing is. It only makes that sound when you've driven for 30~ minutes. Did this car with the timing belt tensioner had the same symptoms or did it even make that sound on cold engine?
This one did it all the time but it doesn't mean you can rule it out as a variable
@@SchrodingersBox Merci for the quick reply mate! I know i shouldnt rule it out, but was hoping for good news, i dont like to have broken loan cars lol. As my own Honda is being repaired.. Do you ever make videos in regardings of Hondas? If so, you're the source of knowledge I want to know :P
Good videos!!
I don;t really make videos on specific cars. To me all cars are the same. They all use the same OBD-2 and the same principles of electrical and engine management.
Thanks for sharing this video.
toolman talal Always appreciate your support my friend- you are always one of the first to watch my new releases!!
Schrodingers Box i like your diagnostic skills and methods .
you make diagnoses simple and step by step and you take your time to cover all possibilities that whey i subscribed to your channel .
thanks again and keep the great videos coming .
I just learned the hard way on my 2009 vw city golf 2.0 is Not a clearance engine....In other words it is an Interference engine and has no clearance from valves to piston .My engine for the record is also 8 valves
Hi, I ma having the same problem, Could you please advice weather its the timing belt or something else. Thanks
Mine was missing teeth from the timing belt.
Good catch
The Drivebelt tensioner is a 16mm open ended spanner just saying
So I have a 2011 vw jetta 2.0 L s. No real accerleration, engine light on wasn't flashing, is now within 2days of being parked, along with the esp or ecp light was on and now off... Engine way louder.. About 20 miles to town, rather not drive to town, so no computer... Just changed plugs, air filter and ignition coil few months ago.. I'm thinking maybe timing belt? Engine moves in Idel.. Any ideas would be great! Thank you
what data do you have that makes you think it’s a timing belt? What is the data that indicates this? Dod you do cam/crank correlation? what’s the timing advance?
@@SchrodingersBox don't have data, that tells me anything.. About a 30 mile drive to town to get on computer I just didn't want to limp it and make the miss fire worse.. Anyway, I changed plugs again, and now I found that plug wire #2 needs to be replaced.. That's my next step. Have appointment next week to get recalls fixed🤦🤷 thanks for your opinion on my question.
Can’t help without data sorry. Good luck.
@@SchrodingersBox all but one are reading as misfires. Buying another coil pack......
whoa i don’t get it- why would you buy a coil pack?? What evidence is there that this is the problem??
Save your money. Get data and analyze it to find the cause. don’t guess.
03 vw golf 2.0 automatic. Making a continuous ring under the hood. High pitched noise only goes about thirty seconds but i can't find nothing about it seems like. I'm new to vws and well cars in general lol.
Yeah you either have to just keep looking or maybe do what I do and that is remove variables systematically to narrow down the source more.
@@SchrodingersBox thanks much I shall start digging into it this week!
Hmm.. lessee now.. thinking mechanically.. whats in the crank / camshaft sensor path?? tensioner and timing belt maybe.. just a thought lol
gbowne1 And a good one at that!!
not a severely bad idea to replace the tensioner and sensor(s), but don't know how or why they didnt diagnose or at least check the rest of that mechanical chain to be sure everything good. to me i see so many people just replace sensors thinking that'll be it and move on.
Thx, great video.
i think i prefer timing chains vs. timing belts. i have actually never had a chain fail and the only reason i have ever replaced one was if i was in there anyways for some other reason and did it as a preventive. chains are stronger then belts and do not generally require tensioners. also belts age and dry out you can have a timing chain that is 20+ years old and still fine because its steel and not rubber. im not even sure why the use timing belts, i think they suck in my opinion. yes chains can wear out but that takes many, many miles (as many as 200k+ miles) and they usually stretch and dont break.
+andrew donohue Agreed! Timing chain fan right here- plus being a high performance kinda guy, nothing beats a chain when running 400+HP I can assure you!
for real stupidity how about an interference engine with a timing belt. has to be one of dumbest things going, but i believe there are quite a few Japanese cars like that. belt lets go and BANG, was that a valve hitting a piston , that engine just became a paper weight in seconds.
I generally agree that chains are preferable to belts, but they can have some drawbacks too. I had a Mercedes with a M104 engine before, with a timing chain that was leaking oil from the cover. It was common to have a leak at that cover as the design had two intersecting planes of sealing surfaces.
Belts don't need lubrication so the issue is avoided altogether.
yeah that's possible how bad of a leak? a small leak is an annoyance and wont leave you stranded. i also think that if you do have a leak that typically its a small leak and as long as you watch your oil level its not much of a concern . a belt will leave require replacement AND it can damage the engine very seriously if it fails on an interference engine. if the timing belt fails on and interference engine, the crankshaft will continue to rotate and the cam will stop. valves meet piston BANG major damage and a possible completely trashed engine.
you dont need a special tool for that tensioner....unless you consider a 16mm wrench a special tool.
Hey Matt, that was an efficient 10-minute diagnosis! Wow I'm really surprised the engine is still running with all those teeth missing on the belt. As for the P0102 MAF code, those VW MAF sensors are prone to failing for no reason, often resulting in a start-stall as the signal to the PCM will be lower than it should be for a certain airflow. Just diagnosed one a few weeks ago...quick test is unplug the MAF and if the car runs fine then you're done lol. The P0340 looks like a circuit fault...wonder if the loose belt hit the sensor and messed it up? Wouldn't be surprised if the new one is toast too haha. You need a scope ASAP to show us some sensor signals :)
Horray for parts changers!
motoYam82 Yeah the fact check engine light only came on after the noise started leads me to believe the MAF is related to the timing. If I had time, I would have checked the CMPS signal actually.
Note I said if I had time... not "if I had a scope"... hmmmmmmm...... And my next video will be on MAF diagnosis.... hmmmmmmm.......
Matt, looking forward to the introduction of your scope...
Louis Pasnik Lol... now I didn't say that!!!
excellent 2%'er diagnosis!
I have a 2019 VW Jetta and all of a sudden I heard a fluttering when I accelerate. I brought it in, and they said they had to order a Torx screw and some bolts, that I should not be driving it like that; so I have a loaner and will pick it up Thursday. I didn't know what to think, it only has 28,800 miles, and it's a lease. I extended it one year; in October I am going to get a new car. Whaddayathink?
could be anything. what diagnostics were done? i would start there.
