You saved me!!!
Retrofitted some OEM angel eyes headlights and blew a fuse! I looked everywhere and couldn’t find it. My scan tool told me there were all kinds of issues with the Vanos, the throttle control valve,and several others; 6 codes total.
Spent the day going over every inch of my ‘99 e39 and could not find out why the car would not start. No smell of gas made me think it might be the fuel pump relay. Flipped over to your channel, and BAM! Pulled the hidden fuses under the cabin filter on the passenger side under the hood, and found a 30 amp blown! Replaced it, and VOOOM! Old Betsy fired right up. Thank you! 😎🇩🇪👍
Man, you are doing a huge service for the humanity!
You are my personal hero from now on. Thanks to your videos I've just finished replacing head gasket on my X5 3.0i (with LPG conversion - that's why no one wanted to touch it) that I bought last year as a dead on arrival project. After checking head bolts upon removal they've stripped the threads in the block after head skim and gasket replacement, so new set of bolts and gaskets out the window. Drilled and re-tapped block using longer 3D (3x diameter) hel-coils (time-serts are not readily available or well known here - we're far behind here in the UK). Then it was putting it all back together, coolant, oil, only to find out that the cow now refuses to start. Great minds and so on, first I checked schrader valve - pressure there, then bought pretty much same spark tester as yours and found out there is no spark. Took me two days to get here. And then I stumbled upon your video. Thank you. The beast is happily purring and me after timing it, drilling block, scratching head surface, loosing money and patience - I became a happy man. Will check it proper tomorrow, but due to the fact that I've rebuilt everything from grounds up I was planning to strip it to some extent to check all connections, then to re-do the timing. You saved me all that. Someone said you can time the engine 180 degrees out, which I think isn't possible, as you set it all when putting chains and timing components for sensors are all on the crankshafts, so I'd say it's not logically possible. Anyway, again, thank you very much, it was the 30A fuse in my case, one to the right from the middle. Swapped, started first time. Missus proud, I'm happy. IT engineer / graphic designer here, with engineering background, but this job was about 3500 miles away from my normal comfort zone. Thank you. If I'm over your end of the pond I'll pop down to buy you some beer. Keep up the good work pal.
I love your "this job was about 3500 miles away from my normal comfort zone" expression.
Cheers from another IT guy working on BMW beauty that won't start yet!
How long did it take you to do that head gasket?
Wow, very impressive. From no start to rough to smooth with detailed troubleshooting. Thank you!
I have been looking for someone like you forever!! I have a 2000 320i e46 with a slew of problems and thanks to you I feel confident in tackling these issues.
EXACTLY what I was looking for, you guys have just given me a lot of things to check, that everyone else just skips over with no detail. Got a fan now, top job guys !!!!
The 50skid is one of the best when it comes down to BMWs engine videos
thanks, man!
50sKid what happens if theres no fuel that comes out of the valve
@@e46alex30 if there's no fuel at the regulator when trying to start you need to check if you have fuel then check the fuel pump then the fuel lines and the fuel regulator
Thank you. It was the fuel pump. No hum when I turned the key forward. Temp fix... tapped the housing with the key forward and it started working!
50skid I have the same problem on my e46 this video educated my knowledge. Now I can't wait to test my coil and spark. Thanks
I am very into Air Crash Investigation type TV programs... I follow that whole heartedly... Now; here is this 50sKid... This guy is brilliant!!!... You may watch other tubes as well... He's just above the notch... Keep It up man!!!
A very good diagnosis without any diagnostic tools/ computers.
This is a much better way of diagnosing an automotive issue as compared to using complicated diagnostic test benches/units.
Cheers n Thanks again.
Hey man your video's are so helpful, i have a E46 2004 330i, it was running like crap, after watching 3 videos', it's all good again
Replaced Spark Plugs, Cleaned Idle Control Valve, ( throttle body, and mass air flow sensor) and new CrankShaft Sensor
This was a very professional training video, please keep them coming and thank you.
That strut tower is mushroomed to high heaven!
You're the BEST 50sKid!
Keep making these e46s videos, they're more useful and precise than any other source.

Greetings! Thanks!
I've been watching your videos for a while now as I have owned 2 bmws in 2 years. I wish you were near me because I would pay you some damn good money to work out some issues with my m56 that I can't figure out
Love your videos! You're my go to TH-camr for all my e46 repairs
50sKid you are awesome!!! I'm fixing my e46 m56. I hope, Next week will change my Vanos Unit and CATs (I wait for delivery). Hope will work ))). Your videos is so helpful. Thank you so much!!!
Thanks for taking the time to respond. I'll give it a clean and then see what I've been missing out on? Thanks man, Top vids don't stop them coming. We need you man, just like we all need cars, computers, personal cell phones!!! etc!
Interesting how a misfire eventually leads to a blown fuse, great upload.
Yeah I wish I had a good scope with all the right accessories so I could have figured out exactly what was going on with that coil.
50sKid You should buy the cheapest pico like the 2xxx series it is not so expensive
Thanks so much I think if i..replace the last item you replaced hopefully.will fix. My idle problem I will let you know. Thanks again ND keep.the videos coming! SAM
Hi sorry to bug you I was wondering I have e46 m56 and gas pump went out can I install a non SULEV gas tank?
These detailed videos are awesome. I have similar problem just now with my 1998 e39 m57 530Diesel. Both fuel pumps in tank are good, transmitter pump under drivers seat works because i have fuel after fuel filter. I have to inspect that tip about checking fuel rail to rule out high pressure pump. Thank you for your videos and greetings from finland.
50's kid, I have a question, thank you so much for your videos. My 2001 330CI is having a knocking sound coming from the top. I've done most of my work from your videos, so my car has been very reliable. Recently, I replaced the Vanos, the coils, and now it's having trouble starting. I noticed the EF-2 fuse blown. I replace the fuse and noticed after I tried to start it, it blew again. I checked the fuel system there is definitely fuel pressure when I turn the key on the fuel is priming. Okay the big question is this I checked the EF fuses on both sides of the fuses but when I got to the EF2 fuse the left side of the fuse did not light up. I'm not really sure. Could it be the coil pack, or could it be just one individual coil it doesn't make sense though.
That humming sound from the engine bay when ignition is on... I have had it and have had it for years. You said you so not like it and that you would check it out. What is it.
Thank you for these vids, after my E46 rebuild it was crank not start, the fuse was blown. since replace the fuse suddenly now misfire on cylinder 3 come and go
Keep doing what you're doing man! absolutely love your videos
+Muhammed Yanar thanks!
your methods and information were very detailed. really a big help.
profesional analysis, wow, best channel in round auto DIY i have ever watched. thank you
Liked all your videos, very detailed. How about a project car? An E30 with M54 engine.
All your video's are fantastic - been no end of help to me and my E46 325Ci MSport! Now you just need to sort the wiring out on that :p
nice video i dont even have a e46 but have a f30 diesel in the shop for 1 week now with only 50k miles
Great video, great to hear the engine come to life! Look forward to next installment on this car.
Hey man i watch a lot of your vids! Just replaced all my power steering lines and hoses using one of your videos! I feel like a capable mechanic now lol I have a 03 325i and it sat over the winter. I started it the other day and it idles fine but when i rev it, it sounds like its missing, the revs are very rough.
It has new spark plugs, coil packs, new disa valve and all intake boots and vacuum lines replaced. Wanted to see if you have any idea about the rough revs? I wished you revved this car in the vid but that's what comments are for! I replaced all my parts thanks to your videos so much appreciated keep them coming!!!
Also i replaced my secondary air valve and ever since i did that it no longer loses and hot gasses pour back into the pump! I can't figure that out its a new valve and hose from the pump. It actually melted the old hose from pump to valve that's how i figured out it doesn't close. Would appreciate your expertise!
sorry for the long comment lol
Nice vid bro, I have a very similar buzzing noise coming from my e36 323i. So far no obvious performance issues relating but I am sure its not supposed to be like it? So hopefully you will address the source of your noise and report on it. I then will benefit from your mechanical prowess. been following your vids from time. You are my go to on BMW e36/46. keep up the magnificent work old bean. Thanks in advance....
The noise was caused by the stuck idle air control valve
Thanks for you videos! Your putting a e46 in 1st place on my wish list!
Thanks man. I have a crank no start problem after replacing the inner heater pipes and manifold on my 2004 325i bmw m56 engine
Okay Perfect thanks Brotha really appreciate your help im.goin to check it my Battery died it's charging. So question what would the next step be if the spark plugs are good when i test them in the coil?
Hey Jason great video , bring that E56 back to live.
Could you put a link for the spark tester please
done, check description
Hi Great step-by-step video! I tried these steps and have fuel pressure, spark in each coil, and no blown fuses. Code is a P0456. Could a canister purge valve cause this, or is there something else I should focus on? Thank you.
Genial, great video, i always learn, i have an E46 and i fix my car. your videos always help, all details explained, thank you.
Did you ever discover why the Idle Control Valve was humming loudly before you swapped the Ignition Fuse?
2001 bmv330ci codes are coming up causing misfire .p1347: misfire cylinder 3 with fuel cut-off p1345: misfire cylinder 2 with fuel cut-off p1343: misfire cylinder 1 with fuel cut-off p0174: system too lean bank 2
Hi great videos been watching over the years. ,learnt a lot, now I have a problem I’ve got an e46 m54 2,5 i engine which has died due age , will explain later, so I replaced engine from a e65 7 series like for like motor however it won’t idle or rev past 3500 rpm but sounds like timing not advancing . Fuel pressure 3,5 Bars , new coil packs . Bosch , and spec spark plugs , please help any thought be great
This is great , I have BMW 2005 1 Series with similar problm. It cranks , but wont start because of spark. The guys have been trying to get it started for the past 2 weeks. I guess this will help
Did they ever get it started
fantastic video 50sKid!
Im not sure when the 50s kid was born. Was it the 80s? The 70s? Maybe even the 40s? I have absolutely no guess what decade it could really be...
80s 😎
Hello, I have an issue with a 316i from 2002. After the engine gets to 90° celsius and if you pull off and stay with the engine started in neutral/no gear it will increase and decrease the rpm up to 1700 and 800 by itself until it will have no more voltage/power at all and die. While is doing like this, behind the car stereo or under the dashboard(that location) you can hear like a click or a short circuit sound...don't understand where is the issue, a few electricians checked but didn't find the cause let's say. Also, I used a lighter voltage meter and when the issue start happening(ONLY after it has 90° celsius) it won't display 13.8 volts anymore, it won't display anything. What I also did(in car repair shop), changed the alternator relay 2 times in 8 months as they said that a short circuit in the car caused that relay to die. Thank you very much!!
Great video. Thank you 50sKid!!
Thanks for another great vid.... been very helpful to me over the last months with my 323ci so cheers buddy!
Just wondering do you think they fitted the whole b30 inlet or is it a new part for m56?
It's a new part for the M56--it's got the supports for the engine cover built into it. Different injectors, different holes I believe.
ive replaced icv and maf sensor and it runs so much better. (it barely bad any power, the car was bought used) but not sometimes the idle would bounce 700-1100 but only when I'm coasting. when I'm at dead stop it won't bounce... could it be maybe the vanos?
Wow! Thanks for the instructional video.
Great videos, having issues with 325i computer, have you ever replaced a computer on 325i?
Good stuff as per usual sir. Big fan from Texas.
love your videos, my 02 325i has a wiered idle where the rpms go from like 1k to 700 rpms, but you really need to pay attention to notice it . what do you recommend me to check?
great stuff on this for sure, jumping from one fix to another. car went from 500 come tow it to 5k running vehicle
you are the best!!
I am learning so much for you
thank you
Mr. Kid Does a 2005 BMW X3 have the same type of Fuel Filter/regulator assembly? BTW whats the Fuel pressure at the Fuel rail for this model.
hello, I have the same problem. I saw the relay, the fuses are okay. Should I try to change my safety if it is not interrupted?
That happened to me today with my e46 at work lol thanks for the video!
Your videos are awesome man. Keep it up.
Another great video Kid, thanks!
excelent job my friend.. and about the noisy.. fan clutch.. why not do the ..fan clutch delete.. I had a 320i and I took out the noisy fan clutch and the blades.. and I had no temp problems or any issue... the secondary fans worked when needed... never had a single problem with that.. and the engine sound is delocious without fan cluth... I reviewed on GERMAN forums and the users say they have no problems at all without fan clutch as long as secondaryies work well.... no need to buy electric fan... i mean it.. german bimmer forums no problem ...running without fan clutch..and it also feels more powefull..
Love this!! Can't wait to see more!
if your car cranks no spark, check all fuse they all good can you tell me what to check next?
So I seen the m56 uses the same DISA valve as the 330. My question is the intake manifold the same also? Because I was looking at swapping the intake with fuel rail throttle body and maf to the 330 with a tune to get some more pep out of the mot
Nice! Love your videos. Keep 'em coming.
awesome video. amazing what you can do with just your brain
Wish you would have shown location of idle control valve.
"All the good stuff!!" lol
Fuel squirting out is not necessarily good until fuel pressure is sufficient
I have a 2004 325i im still trying to fix the no start but going to try this now. But before all this happened my car would sound like a real deep tone like if i put a intake on it or if i had a exhaust leak sometimes it goes away some time it just stays like that for a day. Do you have any clue what it could be cause sounds like crap? One more question how do u no if your relay is bad with out a test light ? Please and thanks for your videos
Nice vid, you have helped me out loads with your vids👍thanks a lot🙂
I love your explained video love you man .
Nice work! Great video!
Great videos but its only a matter of time before jafromoble releases another video
Wish he'd do them more often!
So here'e the problem im having and im confused! I've replaced soooo much... Camshaft, Crankshaft, Spark Plugs, Ignition Coils, Fuel Pump ( i Need to change the fuel pump Filter and maybe the fuel regulator) ... None of things i did change help the car Start.. It would Crank but no start. Change fuses and relays as well and to no avail. Tried this method ....... tried it ... tried it tried it then boom the car Started.... Ran for about 30 minutes then Cut off... Didnt't cut on again until i did the process over. It seems as if it would build compression then lose it again. Doesn't have enough power to Drive, Reverse or nothing even when on and running. Checc Diag tool and it's throwing me codes for things I changed already. SUPER CONFUSED... What's my next move?
e46 Bmw 2004 325ci
What fuses do i need for all sockets i see that they sell variety packs of fuses but im not sure which ones to purchase. I own a bmw 325xi 2002 m54 engine
Are you going to be replacing rubber membrane too if you rebuild DISA?
Hey man, thanks so much for putting these videos together. Theyre very informative and I really enjoy watching them!!
I replaced the CCV and hoses dealer parts I torque check the bolts on the valve cover smoke test good what's next????
Thinking about buying a 2002 bmw 316ti compact that cranks but doesn't start. The owner said it had a misfire so he got the computer checked. Now it just cranks but wont start. Should i buy it?
Hey so I checked all my coils I'm getting spark threw all 6 coils so could it be my spark plugs need to be changed?
if you pull a plug out, put it in the coil, and crank the car, and you hear/see a spark--your plugs are good
Can bad coils just cause the car to not start ? And can a fuse be blow without it looking damaged ?
I am so glad I found this channel lol.
Need to try this on my E92, it cranks but it dont start! Thx for the video! :)
amazing detailed videos!
1996 BMW Z3 crank no start where can I find a gas pump relay
Autozone
In your glove box top left realy
I really need ur help
Did you ever figure out what the buzzing sound was? I have the same issue.
I recently had an issue where my upper radiator hose broke and coolant was sprayed all over my windshield. The issue is fixed bit now when I try to start my car it cranks then dies, it will turn over but not enough to stabilize idling and keep the engine running. I replaced the battery because it died from sitting during the holiday weekend I tried starting the car and no Bueno. I checked my spark plugs and ignition coils and they're all good.
Edit: Also, could a leak from a broken upper radiator hose cause issues with the ICV?
Any suggestions? Please, before I have to go the mechanic route and get juiced for my money.
Great Job Kid. 😀
My 530i will not start fully. It’ll crank. I unplugged the negative wire still no luck ! Someone help me !!!
Hello I need help. I have a 2002 320d, having crank no start, found a 5 amp fuse that was not lighting up, found a fuse that did light up swooped it into 22 Diesel engines but still got no light, can you help
I have 328i at first I have sparks but then it goes aways and it won't star any idea? Thanks
Hey normally mine fires up at 1000 rpms, then goes down to about 600 rpms, but if I let it sit an hour or two and crank it, it'll fire at 300 rpms and work it's way to 600 like normal, any clue what that is? Never has it not started though
@50sKid What is your experience with these coils in general? I've found them to be a particular weak point. My mom and my sister both have E46s with N42/N46 engines. After replacing the 3rd single coil i said screw it and swapped all 4 in both cars. They seem to go bad regularly.
Yep I've had similar experiences. Replaced them in two minis
thanks from morocco 👌
ive had an occasional rough cold start idle, one time it even shook the entire car, but had no fault codes maybe I should take a look at the idle air control. Also, does your m54 have a sound on a cold start that sounds like it's being starved of oil or something? goes away after about 5 seconds and it is only audible if the doors are open. 86k miles
Check your fuel trims to find out if you have a lean condition.
okay thanks I guess I'll hunt for a tool that can do that I only have PA soft.
Check out my review on the Foxwell scan tools. The NT201 is the cheapest I've found that can do fuel trims.
So I have a 2004 325i that threw a p113 code so I got the new IAT sensor, took the plastic cover off to get to it and I see where it should be but there's only what looks like the broken stub of the old one even having the remains of the clips on the sides of the IAT but nothing else. The wires that would go to said sensor were nowhere to be found. I read that if the clip on the mass air sensor has 5 wires on it that the IAT is built into the MAS. Does this mean to address the code I have to buy a new MAS? I believe the engine is an M54 but I'm a dumbass so...
Great video!
