Best diagnosis/repair video on TH-cam period. Iv had p034100 on my 2.0 TDI for a long time and iv spent a lot of money changing camshaft sensor / crankshaft sensor / cambelt , nothing worked iv had this verry same problem. And finally it’s fixed thank you!
I like that you put fender covers on the car. I watch a lot of other videos doing car repairs and very few of them used fender covers, and they have belts on with buckles and rivets on the jeans.
When I was at the Buick dealership back in the 80's we used them and were also issued two moving blankets, one for the fenders and one for the seat and it was a big no no not using them. Work pants with no rivets and belts were to be worn with the buckle moved over to the side on the hip.
Hi Dan the man , I have done a lot of diagnosis over the years and enjoy looking at what other professionals have found out ,this video is well worth watching .
My neighbour had the same fault" long time to cold start" yet good when on his 2007 VW Golf diesel, a couple of times there was a non-start ( battery discharged due to excessive cranking) garages frightened him with potential big bills for a major engine stripdown, neighbour was ready to scrap his car, after watching your video, neighbour had the similar part replaced, part cost was £80, result one fixed car, no need to replace car, ££££ saved from wastage, Thank you Dan, you are my hero and first port of call for DIY diagnostics.
Thank you legend!! I think I might have the same problem with my Audi A3 (2014). My mechanic said that that VVT might be a problem. I searched a whole internet to find what that part is and why is it a problem, and then finally came accros your video. Thank you very much
Somebody should be changing their oil more often... A 2014 that needs an oil flush already?! Also VW should've designed a screen for that just like everyone else. That car sounds great for a diesel! We don't get cool stuff like that in the US! Great video once again Dan! 👍
watching your videos is like doing a hands on TAFE course on latest auto technology from my IPAD while lying in bed. coming from an electrical/electronic background, i am quite interested in how these systems work. it is so valuable to see the wiring diagrams, waveforms, the physical appearance of the systems (eg VVT control unit) & where they are typically located in an engine bay. today i learnt about crank angle sensors, camshaft angle sensors, lp & hp fuel pressure sensors (and their analog OPs). i note how you remove some things to get at other things. of course, we see a sanitised version & don’t get dirty hands - nice to leave that to you! while nowadays i will mostly leave the servicing & diagnostic of my car to my local mechanic, such knowledge is good to have when dealing with a service centre or checking out the engine bay of a new vehicle I’m considering purchasing. thank you so much for this valuable info. keep up the great work! your fault finding data should help the designers of these systems upgrade & improve their reliability.
Awesome diagnoses. I have to say I am surprised you didn't check PCM command to VVT solenoid to rule out PCM problem. Your channel will be huge. Keep up. Cheers👍
KY Home Garage KY Home Garage , the engine timing was correct after a few seconds. So it was clear that the PCM was able to correct the problem. The timing chanced when the engine was not running. So there was no need to check the PCM, because this had to be a mechanical problem!
NICE VIDEO ,,I HAVE A SIMILAR PROBLEM, IT's A 2008 MINI COOPER NON TURBO,1.6 AUTOMATIC WITH A EXAUST VANOS CODE, SIMILAR VALVE WHY DIDN'T YOU TRY TO CLEAN AND FLUSH THE DIRT OUT FIRST ON THIS PART..??ALL THE VIDEO I WATCH CLEAN & FLUSH FIRST TO SEE IF PROBLEM IS RESOLVED,, I COULD WATCH YOR ASS ALLDAY DO REPAIR VIDS WOW
Great channel dan. I’ve been in this trade for forty years now and still there’s plenty to learn. Technology in the automotive trade is always changing so diagnostics are getting harder. In about twenty years time there probably be no more production of combustion engines they will all all be battery powered and then there’s all that technology to learn about.
It is very helpful for me and my lovely Audi A3 2.0TDI 8V Sedan's engine is same as VW Golf Mk.7. If I got this problem then I can fix it with your video. Thank you for your video, Dan.
Thank you so much Dan.! I am private mechanic and I found your video is very helpful. I love diagnose and I love to fix things right!! Thank you again for all videos you uploaded it. Have a great days Dan.!!!! :).
Great video! So thorough and professional. American VW dealer service could learn a thing or two from you. I have a USA model 2015 Sportwagen TDI (EA288) with this same long crank problem, but my VVT appears to be the newer version or different altogether as I don't see the reservoir on it. Another odd issue I have is I get a significant hiccup or dead spot on the throttle after a cold start, within about 1/4 mile, a real doozy when speeding up to get on the highway. Both of these seem to be weird phantom issues that the dealer won't fix.
Cold start hiccup is usually warm up procedure and EGR switching from open to closed very rapidly. This was also common on CKRA 2012 -2014 TDI motors in USA, particularly in the 6 speed manual versions. Try using just a little more throttle on acceleration, or run the rpms up another 200 rpm per gear before shifting. This is rather common on 2nd to 3rd gear and 3rd to 4th gear shifts on the manual versions.... The DSG versions, it is almost undetectable.
@@randyvanvliet226This issue I have noticed on my 2.0 EA288 150hp manual 6 gear. Firts time I have noticed it was during the regeneration process as I drove it in a 3 gear and around 2500+rpm...it does not always happen if throttle pressed gently but sometimes it happens. Anyway this is my first and last German car...going back to Japanese reliability, never failed me and never brake.
Did you get it sorted by any chance? My mechanic said there is no vvti on a seat variation of this engine , so wonder if it’s the same issue as for gtd?
@@robertasradzevicius7336 i havnt got round to fixing it just yet,ive just learned to live with it ,once the car gets going its fine..ps my seat leon has the exact same part that dan removed .
I got a polo model having late starting problem. Dont know how, timing belt jump its 3 theeth. That tooks long time to get started. Was bit hard to find the problem on that time. Bcs i was only considering fuel supply system. But at the end i fixed that. But thru this video i have learnt the right process to deal with late starting problem.
Having replaced one of the VVT solenoids on a gasoline GM 2.2 L recently, I was advised to change oil more frequently because dirty oil will clog up these components and cause them to fail. I will assume this to be true also in the VW 2.0L TDI. So while saying all this, why would I follow VW's recommended 10,000 mile oil change interval? Would it not be in my best interest to change the oil in my 2015 2.0L TDI Jetta more frequently to avoid this type of potential problem? A 5,000 mile interval oil change seems to be more re-assuring to me. Thanks
Try 7500 mile oil change intervals first, to see if problem gets eliminated. Make certain you ALWAYS use a VW 507.00 certified oil for your oil and filter changes, do NOT substitute!
"It cannot be" was my thought when I saw the timing change. It all makes beautiful sense once you know there is a VVT. My friend has had his Golf GTD in the shop a lot. The guys here do not speak English so I cannot point them to DDan. (I drive KIA.)
Great Video Dan and good explanation of what was going wrong. There is however one area I do not understand. What was the logic to move immediately from low fuel pressure to timing? With no fault codes I have to admit timing had not even entered my thoughts.
Nice Video! Awesome work! But i can tell you, that the same CUNA/CUPA or other EA288 without VVT get the same Issue where nobody had found the Solution for!
U are great thank you so much that's how a mechanic has to be Pls can you tell us what's your degree?! It's look like an engineer Your biography pls Waiting for more videos ^^
Excellent diagnosis as usual. Thank you for taking the time to make the videos you do. You need to talk to your son about not wearing a seat belt however.......it sets a bad example to other young lads, unless he has some sort of medical exemption..
I have the same problem with first long start (diesel passat b8 2.0 tdi). Sometimes I need to start for about 5 times because engine stalls after a few seconds after starts. Is it possible that because of this fault P034 100 my engine stalls when I’m driving? I’m driving and everything is ok, then it seems that pressure is gone and engine stalls. As I understand this fault shouldn’t lead to engine stalls, but I have only this fault (P034100) after checking OBD. Thank you for your content.
Dan, is there something like an spring loaded accumulator or filter on the left side of the old part? My background is in hydraulics. What happened to that valve, we call that "spool valve silting" in our industry. Nice job on the diagnosis!
I have a Seat Leon with the same engine. By Seat it's with Motor code CUNA. I have the same problem for a Year now. I was to Seat Dealer, they changed some sensors. What was strange the problem desepeard for a while but it's back now. I will show them your video :). So sad that now the owners are the ones researching wath is wrong with the cars and the dealers and most of the service's just change parts.
@@wojciechwojtczak6402 Unfortunately i haven't replaced the part that`s shown in the video. I had 3 weeks a go a wiring problem, two plugs (one on the camshaft sensor and a second on the Electrical water pump) was damaged and needed a replacement. This did solve the problem for a short time. It seams that every time my camshaft sensor gets relearned or reset with a tester, the problem disappears for a while. So the problem must be in the camshaft area and not with the fuel system. And a other strange thing is that before the problem reappeared in the 2 weeks time before, i noticed that every start is getting a little bit longer. It took a little bit more time but no Error message and i would recon it was even then under 3 sec but it was enough for me to notice.
Congrats for this absolutely great job! Do you think that warranty may cover this issue? Do you also think that this may affect somehow the engine in the long term if not solved? Hello from Spain!!!!
I am no car expert, but I think small changes in valve timing should not cause non start. Maybe here we have quite big timing change. Each tooth corresponds to 12 degrees, so 7 teeth difference is 84 degrees for crank axle. If the intake valve is open long time during compression stroke, the compression ratio will be too low the ignite, when there is not yet turbo pressure.
I enjoy watching your videos and fixed many problems by do it your self in my 2015 VW Passat TDI . I have the same issues in my 2015 VW Passat TDI in USA which has the same engine (CVCA) as described in your video. I have two questions for you. 1. Can I replace only the VVT bolt without replacing the housing and the solenoid to fix the problem ( I have the the same VVT system as shown in the video and not the updated system) . 2. When removing the VVT bolt, can you please explain the procedure how to lock the cam shaft by inserting the locking tool through the valve cover. I really appreciate your reply and thank you in advance.
good video as always but how did you know where to dig to find the problem. I mean there could be a number of other issues that would cause similar symptoms.
Thanks for the explanation. I just unfortunately face exactly these symptoms. I just wanna ask you. How much is it critical. I have 5000 km left to next inspection ( only couple of months in my case with less starts). Is it fine to wait or I should drive immediately to the garage? Can anything apart of the battery get damaged ? Thanks
The higher pressure fuel system must have a very very small leak. So it’s loosing prime when it sits for a while. Once the car is running and you shut it off for say 2 hours I bet it fires up right away because it hasn’t fully lost prime yet
Very helpful and well explained video. Could you by any chance let us know what torque settings did you use for the 3 bolts of the vvt housing and valve bolt? Thanks
I have has 2 Golf diesels , they all went 450000 km+. I only got rid of them do to rust. I never had any oil related problems. I used to change the oil every 5000 km. I suspect the recommended oil change interval recommended by VW is way too long. Oil is cheap
I'm looking to buy a 2015 golf 2.0 tdi dsg tomorrow with 70.000 miles. Are they trouble should I buy or not. Beautiful car but I've been told there not worth the trouble?
Hi great video and I've had this problem for some time, I've had the car in at vw and other "German specialists" yet I still have the P0011 fault code! They changed the VVT solenoid bolt but I see they didn't change the housing so I still have the old one on with the extra part which they've since removed. I have the new part being fit this Thursday. Could that be the issue? Also what was the purpose of the old part they removed anybody? Thanks
I have this issue on my Amarok 2.0tdi - Long crank 1st time, shorter crank 2nd time - BUT no error codes. Drives perfectly every time - just the long crank time. Help!!
Dan, is it possible that the vvt bolt makes a ticking noise ?........ My car ticks but no warning light or errors from the injectors. Its also not the valves that are ticking. And it ticks for my feeling exactly from what you call the VVT.
Hello Dan. Is it safe to just unplug the injector connector to perform a relative compression test or you run the risk of frying the driver in the computer?
Hello, I have a Tiguan 2 2017 2.0tdi 190km DFHA. Unfortunately, this engine does not have this adjuster. After a long stop the engine can sometimes turn off longer, but I don't know what could be the reason. The car has a mileage of 70,000 and it is an authentic mileage. In addition, when the engine is cold, when accelerating the car between 1200-1500 revolutions and with a slight addition of gas, there is a kind of knocking combustion. When the car reaches 90 degrees, practically everything returns to normal. Auto, being in the service and after diagnostics, they said that all engine parameters were perfect, but this sound, according to the service manager, should not occur. They only gave me some fuel additive and told me to watch if it would improve. Unfortunately, it did not help. when adding gas and starting the engine for a longer time, it drives normally after night, without any jerks, etc. Burning about 7l in a mixed cycle.
Great video Dan! Very very good job! I own a 2015 Passat 2.0TDI and it has the exact same issue. Could you please share where is the little filter/screen thing that you show in the video? And how do you know if you need to change the valve or if it's just clogged and can be cleaned? /my plan is to give it fresh engine oil, filters, clean the vvt valve and see if it helps. If it doesn't then change it to a new one/
I had the valve changed, I'd recommend changing as opposed to cleaning it but make sure you have the housing done at the same time so it's receptive(which I didn't do) have you since had anything done?
@@krisnicholson1192 Yes, I had some more searching on the internet, and found that it's enough to change the valve only without the housing. My mechanic changed the valve through the smaller hole (he removed the black actuator and that hole was enough to replace the valve). I already changed the valve, new oil, new filters and the issue is GONE! The fear of starting my Passat B8 is not there anymore, it feels so good to be able to start it at any time without issues. Thank you very much DiagnoseDan!
Great videos Dan, just a question please, the oil flush product is Maumo 5in1 oil system flush that you used, is it for deisel and petrol engines, and can it be purchased online to the uk, thanks
Hey man I'm wondering where I get the new part you used in your video. Can't find it anywhere and I need it asap. Would be really cool if u could respond
I removed the VVT valve, but I did not jam the camshaft, and when I put the VVT valve back, I got error P0016, is it possible that the teeth moved?
awesome video, and VERY nice approach for troubleshooting and customer-care. hitting subscribe button)) what key is used for oil filter? is it 76mm 14-flutes? will check what comes in my 2015 ea288 engine :)
When I was changing parts on the car, my mechanic didn’t keep the timing belt in place, and when he screw the bolt on the timing was changed by one tooth. When we turned on the engine we immidietly heard a wierd sound and stopped. Do you think this already did any damage on the engine? Tnx Dan
Yes, if the timing is off by just 1 tooth than it shouldn’t be a problem. We just set it back on right faze and it was ok. If you have set your timing belt off by more than one tooth and started the engine, it probably doesnt work anyone or didnt even start in first place. So if its off by a little its repairable

I am no car expert, but I think small changes in valve timing should not cause non start. Maybe here we have quite big timing change. Each tooth corresponds to 12 degrees, so 7 teeth difference is 84 degrees for crank axle. If the intake valve is open long time during compression stroke, the compression ratio will be too low the ignite, when there is not yet turbo pressure.
Ur videos are amazing Damn keep up the good work
Thanks !😉
I enjoy watching your videos and fixed many problems by do it your self in my 2015 VW Passat TDI . I have the same issues in my 2015 VW Passat TDI in USA which has the same engine (CVCA) as described in your video. I have two questions for you.
1. Can I replace only the VVT bolt without replacing the housing and the solenoid to fix the problem ( I have the the same VVT system as shown in the video and not the updated system) .
2. When removing the VVT bolt, can you please explain the procedure how to lock the cam shaft by inserting the locking tool through the valve cover.
I really appreciate your reply and thank you in advance.
Hello
Did yoi already replacement valve?How do you lock the sistem?
Thanks
Great job. fixed it again Dan no bother to you. Do these modern vw engines have a low pressure pump in the tank?
good video as always but how did you know where to dig to find the problem. I mean there could be a number of other issues that would cause similar symptoms.
Great and informative video. One question, where do you back probe the crankshaft sensor?
Thanks a lot for this video , its very use full sir
Your welcome!
what is the tightening torque for the vvt cover screws?
I have a vw mk5 with the 2.0tdi bkd engine with exactly the same symptoms. I'm wondering if it has that vvt system as well. Thank you for the video!
Amazing, Cheers from Mexico!
CometeUnTamalito Thank you🇲🇽👍
Thanks for the explanation. I just unfortunately face exactly these symptoms. I just wanna ask you. How much is it critical. I have 5000 km left to next inspection ( only couple of months in my case with less starts). Is it fine to wait or I should drive immediately to the garage? Can anything apart of the battery get damaged ?
Thanks
hi sir , thank you for all what you do for us . i want ask you if this valve control intake cam only or both intake and Exhaust
thank you
One com only!
Thanks for the great Video DAN.
The higher pressure fuel system must have a very very small leak. So it’s loosing prime when it sits for a while. Once the car is running and you shut it off for say 2 hours I bet it fires up right away because it hasn’t fully lost prime yet
Hello Dan., on idle vvt must show zero degree, otherwise it needs to be replace, plz correct if i wrote wrong
Very helpful and well explained video. Could you by any chance let us know what torque settings did you use for the 3 bolts of the vvt housing and valve bolt?
Thanks
Any news about those torque ?

I have has 2 Golf diesels , they all went 450000 km+. I only got rid of them do to rust. I never had any oil related problems. I used to change the oil every 5000 km. I suspect the recommended oil change interval recommended by VW is way too long. Oil is cheap
Hi Dan :)
The cupa motor has no variable phases and there are problems with starting. What do you need to check? There are no errors.
I'm looking to buy a 2015 golf 2.0 tdi dsg tomorrow with 70.000 miles. Are they trouble should I buy or not. Beautiful car but I've been told there not worth the trouble?
Great job Dan 👍
Hi great video and I've had this problem for some time, I've had the car in at vw and other "German specialists" yet I still have the P0011 fault code! They changed the VVT solenoid bolt but I see they didn't change the housing so I still have the old one on with the extra part which they've since removed. I have the new part being fit this Thursday. Could that be the issue? Also what was the purpose of the old part they removed anybody? Thanks
I have this issue on my Amarok 2.0tdi - Long crank 1st time, shorter crank 2nd time - BUT no error codes.
Drives perfectly every time - just the long crank time. Help!!
Hi Dan, thanks for the great video! May I ask if it could be the case with the 1.6 TDI engines? namely CLHA? my skoda does this every now and then.
Dan, is it possible that the vvt bolt makes a ticking noise ?........ My car ticks but no warning light or errors from the injectors. Its also not the valves that are ticking. And it ticks for my feeling exactly from what you call the VVT.
doctor dan nice job mate
crist john 😉👍
Ive got this part on my vw golf 2.0 tdi ea288 but its not causing a problem at 38k , but have dealership warranty .
Hello Dan. Is it safe to just unplug the injector connector to perform a relative compression test or you run the risk of frying the driver in the computer?
Just a question. Why was the engine binding, Bad Rings or crankshaft bearings?
Do i have to fixate both sides of the camshaft the one on the side and the one on the top? Or is the one on the top enough?
Did you get a answer? Or did you just lock the camshaft on the top?
@@dansch911 locked both
Hello, I have a Tiguan 2 2017 2.0tdi 190km DFHA. Unfortunately, this engine does not have this adjuster. After a long stop the engine can sometimes turn off longer, but I don't know what could be the reason. The car has a mileage of 70,000 and it is an authentic mileage. In addition, when the engine is cold, when accelerating the car between 1200-1500 revolutions and with a slight addition of gas, there is a kind of knocking combustion. When the car reaches 90 degrees, practically everything returns to normal. Auto, being in the service and after diagnostics, they said that all engine parameters were perfect, but this sound, according to the service manager, should not occur. They only gave me some fuel additive and told me to watch if it would improve. Unfortunately, it did not help. when adding gas and starting the engine for a longer time, it drives normally after night, without any jerks, etc. Burning about 7l in a mixed cycle.
So there is no spring preload on this gear? That turns it back to default after oil pressure drops?
Great video Dan! Very very good job!
I own a 2015 Passat 2.0TDI and it has the exact same issue. Could you please share where is the little filter/screen thing that you show in the video?
And how do you know if you need to change the valve or if it's just clogged and can be cleaned? /my plan is to give it fresh engine oil, filters, clean the vvt valve and see if it helps. If it doesn't then change it to a new one/
I had the valve changed, I'd recommend changing as opposed to cleaning it but make sure you have the housing done at the same time so it's receptive(which I didn't do) have you since had anything done?
@@krisnicholson1192 Yes, I had some more searching on the internet, and found that it's enough to change the valve only without the housing. My mechanic changed the valve through the smaller hole (he removed the black actuator and that hole was enough to replace the valve).
I already changed the valve, new oil, new filters and the issue is GONE!
The fear of starting my Passat B8 is not there anymore, it feels so good to be able to start it at any time without issues.
Thank you very much DiagnoseDan!

Great videos Dan, just a question please, the oil flush product is Maumo 5in1 oil system flush that you used, is it for deisel and petrol engines, and can it be purchased online to the uk, thanks
I don't know i get it from my Local suplier.
@@Diagnosedan thanks, no problem, kind regards
Hey man I'm wondering where I get the new part you used in your video. Can't find it anywhere and I need it asap. Would be really cool if u could respond
I got it from the dealership
@@Diagnosedan can u maybe send me a link or something? Literally can't find it and at my dealership they wanna sell me the same one
@@feretzul It's been over a year i can't remember the part numbers but it must be in the video
@@Diagnosedan nah cant find it :(
@@feretzul Part numbers are listed towards the end of the video quite clearly.
I removed the VVT valve, but I did not jam the camshaft, and when I put the VVT valve back, I got error P0016, is it possible that the teeth moved?
awesome video, and VERY nice approach for troubleshooting and customer-care. hitting subscribe button))
what key is used for oil filter? is it 76mm 14-flutes?
will check what comes in my 2015 ea288 engine :)
Den B Thanx😎
Thanks Dan , always a help
When I was changing parts on the car, my mechanic didn’t keep the timing belt in place, and when he screw the bolt on the timing was changed by one tooth. When we turned on the engine we immidietly heard a wierd sound and stopped.
Do you think this already did any damage on the engine?
Tnx Dan
Oops!😬 I hope your Lucky but it doesn't sound very good!
has your car been repaired, I'm afraid I have a similar case
Yes, if the timing is off by just 1 tooth than it shouldn’t be a problem. We just set it back on right faze and it was ok. If you have set your timing belt off by more than one tooth and started the engine, it probably doesnt work anyone or didnt even start in first place. So if its off by a little its repairable
Does anyone have a link for the timing tool that’s needed to carry this out??
dan part number of timing tool
Great work mate , i wanna become like you , any advice on where to start ? I have an okay automotive knowledge. Thanks
Does anyone know exactly how much torque does it need for tightening the new oil control valve?
