Thank you, you clever man. Unplugging the camshaft sensor was the clue I needed when I had been looking for a fuel fault. If you were here, I’d buy you a drink.
If there is still no start with sensor unplugged do I then follow up fuel problem?
Exactly what I did. In my case pointed to no fuel from pump in tank. While following to replace pump came across bad wiring.
Mine is doing the same thing need to do that tomorrow morning I was about to buy fuel pump but let me try this
a real mechanic, not just a parts changer, getting rare....
*Good luck even finding a good parts changer nowadays...I'm lead tech and all we getting applying is lazy lube techs that sit on their phone all day*
@@donjulio5045 good time to ask for a raise...it's been eons salaries have fallen back on real cost of living...
Thank you so much!!! My 2000 Jetta tdi with 419,000 miles (that I put on it) wouldn’t start today. So while I was in a parking lot I watched your video and it was just what I needed to diagnose the problem. My fuel injection pump pulley had slipped 1/8 of an inch from the last time I did a timing belt change a year ago. So I grabbed a socket set and a couple wrenches and 15 minutes later it fired right up and I was able to drive back home 😀.
You may have just have saved me a small fortune. I was losing hope to an extent. I drove the car parked it up, then it refuses to start that Evening. Servicing has been kept bang up to date. Interestingly its timing belt, and water pump were replaced only several weeks ago. It has been such an easy starter to date, and was seemingly running nicely. It delivered 65.2m.p.g running up to Morecambe and back to Cornwall. I've precious few pennies to replace the car with at this time. If Your advice pays off here Gerard I will really need to send you a decent drink Sir.. Thank You so very much for posting a clear concise video.
any updates ser?
This is the exact issue my car is having now I finally have some direction and know how to handle this. Thank you so much you have saved me so much money
How did you get on? I’m having the same issue
Brilliant video wish you worked at my work im a young apprentice and need someone like you at my work. Very good explanation and really helpful
I’m in South African u just helped me big time...thanks bro 👍🙏🏾
Great stuff 👌👍🙏
wifes old car has been sitting for 6+ months, started maybe 3-4 times and not driven. I started to drive it and noticed hard to start when cold. I popped the bonnet to check the battery charge and there were 2 spanners, thinking I left them in there for 6 months after a service, went and checked them after watching your vid and they are 13/19mm, I must have played with cam timing... without lifting a spanner to it, id say your vid has got me in the right direction
Thank you very much
My caddy has been playing up for a month or so cranking over for 30-40 seconds before starting . Adjusted the timing as it had slipped as in the video now starts 1st time
I recently bought a cheap a vw bora 1.9tdi pd100. Took about 4 seconds to start. So I was looking around the engine bay and noticed the cam position sensor was unplugged and taped up 😮. Plugged it in and no start.
Decided to check engine timing. The crankshaft pin locked in and cam was about a tooth out.
Maybe a touch more. Retimed it all and plugged sensor back in bingo. Runs like a dream now.
Lovely video, it's exactly the problem with my Seat Ibiza 1.9tdi 2008. I just noticed by this video that the sensor might not be the problem but yes the camshaft out of position since a cold start will make a knocking noise from the engine. Will be great after 5 mins but since the sensor is telling me something is wrong it's a lot easier to follow this amazing video before blindly buying a new sensor. A 10000000 thanks to you !!
Mine at cold start taps for about 5 seconds then goes away.
Nice Diag Gerard good Bias voltage 5v on the signal wire the torsion values are as close to zero as possible
Cheers for that Ian 👌🙏
When testing the signal wire. Shouldn't the cam sprocket be in a certain position? Cam sensor is a potentiometer so surely if in wrong location wouldn't the 5v be pulled to ground thus sending a signal of cam position.
Edit... scrap that. You run the test with sensor unplugged. Only relevant when backprobing.
Good job. I've worked on loads of these and didn't realise the torsion could be so far out as to cause non start.
You legend followed this video checked plug to rule wiring out 5v on all tests so adjusted torsion on cam and wow 1st click fired up
Just helped me out loads on my golf thank you. More videos
Gotta drive over after the wife's 2015 TDI 2.0 refused to start. No issues so far and car has only 60K miles, barely broken in (lol). I'll definitely look into this cam position sensor.
Nice job man. Shame I don’t have anyone like you near me who could sort out my P0028. Tried 2 different garages and neither of them seemed to have a clue.
My 2013 Passat TDI just started doing this a few days ago. We'll have a go at it and hope it's this simple. 😁 Ty
Did it work
i am having the same problems. had me change the fuel pump. and the problem still persists. LMK if you got yours to work
Please let me know if it works I have same problem with 2013 vw passat
Did you get it to work ??? My 2015 2.0 TDI just quit at the mall. Cranks, won't start. Going to have to check this out.
Great video. 0-0.5 is the tosrion value
Great video. 0-0.5 is the tosrion value
All VAG owners become a mechanic in no time, hahaha. I've learnt a lot about TDI because I bought a high mileage VW Caddy 1.9 TDI. Part after part after part has been replaced my me. Things keep breaking at 300,000km. My van is practically new now after all the work I've done to it. It's drive another 300,000kms
I know exactly how you feel I have a 1.9 2009 golf
Vw 2.5 😂😂 u right i done lots of parts and scans
Torsion value is written in pen on the cam cover on them all, usually doesn’t last too long. Supposed to be written in the service manual too. Some can be up to 5 degrees either way, 0.0 is usually the best benchmark to adjust from when doing it.
We used to have a dude like you at our work but unfortunately he left & as far as I know, he's out of the trade, it's a shocking waste, he'd make an excellent trade school teacher 👍
Thank you Lance, I appreciate the comment.
It's such a shame when we lose good techs to other jobs or roles. They are needed badly these days
@@GerardBurkeBurkesGarage I have a jetta 6tdi it does not make start. If you put quick start on it it will start bt it does not Rev. No power at all. I tested the injectors they are 100 % correct. Vcds is showing nothing.
Must be running to set torsion values.
Possible MAF problem or intake air leak.
If you have a lift pump, make sure it is providing pressure.
Great work nice video sir love from India ❤️👍🙏
Thank you
just shredded my timing belt a few days ago. Not sure if i did any damamge. Belt is still on but missing a whole section of teeth. ill have to check timing and see. wish me luck
Thank you very much i will try this on my BXE with hard starting issues, we changed injectors and fuel pump still same issue.
Great video Ger my car is in a garage at the moment it had a leak in a fuel line its now repaired but wont start ..
Bleed pump and injector lines if it is ALH engine.
@@bobirving6052 got it sorted after a week..
For 2.0tdi 16v Inlet cam (Torsion should be 0), the exhaust cam should be adjusted so the live data for fuel consumption is flicking between 0.4-0.6 l/hr.
For single sprocket 1.9tdi for example torsion is also 0
THANKYOU 🍻
Well diagnosed and step by step explained, great video many thanks 👍
Thank you Arian
Thanks for your video; I just got my engine running.
Will give this a try in the morning, hopefully it will get it started 👍
Quality work Ger, that was an out of the box diagnostic find, loved it "bualadh bos"
Once again, thank you very much
Thanks Anthony, I appreciate it 🙏
What if engine starts with easy start and runs fine. But will not start normally
I have that same problem mine is polo 1.9 tdi same engine I move it without cam sensor and it doesn't pick up well when I plug it is shut down thanks for the advice
nice fix gearld. i done a lot of these non start over the years and the first thing i always ask is did the costumer put in wrong fuel 😆
It's the right question to start with 😁
I have the same symptoms about the vw tdi engine but without the fault code as well as your ,so I need to check out the fuel pump or injector.
This was the first video I found with substantial information. Thank you.
Hi, I really liked your video. You explained very well. My car has the similar problem. I’m going to sort it out. Thank you!
You the man👊✌️, thank you
🙏🙏👌👌
It's a 2L TDI, BMN engine 170bhp, 2006
Good video this brother, going to save it to my playlist now.
Great job Gerard, fair play, Thankyou :):)
Thanks Pat, the VW will live on for another while 😉💪
Good video and very well explained.
Thank you Luis 🙏🙏
great one
Thank you very much! I have been fighting with my brm for a while now. I just installed a stage 2 cam from kerma TDI and im not getting a torsion value! I am using vcds and I don’t know if I can see camshaft speed on there. I will try out a couple tips you gave in the video!
You don't need to see camshaft speed,what you need to see is the timing limits within specified tolerance.
@@eugeneoreilly9356 I got it figured out finally haha it ended up that all 3 cam sensors I got were all bad. If anyone gets one I would get it straight from Kerma. I got 2 from autozone and one from rock auto. None worked except the one from Kerma
@@cecilshannon2586 glad you got it running.
I bought cam sensor from Rockauto and it works fine.
Thanks for informative video. However my issue is engine will crank but not start first thing. Wait 5 minutes and it starts and runs perfectly. I’ve had fuel pump replaced and ecu checked out. What would you suggest next?
What a great video sir, wow!
I wonder how much beer was involved in coming up with the logic to prevent the engine from starting when the cam sensor is out of range versus starting with no cam signal at all.
I thought exactly the same, perfect logic!!
😅
I have same issue. Its all the way to the left. However there's markings from who has changed it previously and it lines up with them. Should I still move it to the centre?
My jetta iv 1.4 just cranking. I came. With it from mpumalanga but when i arrive here at joburg. After 2 weeks when i start it it just cranking til now.
I love you man. Solved my problem 🙏🏼💙😂
Hi Gerard, Thank you so much for sharing such in-depth knowledge, much appreciated. By the way, where are you based in the UK?
My 06’ starts are idles nicely, it’s only once you press the throttle the RPMs gets up to roughly 2000 and the motor starts jumping like it has a two-step then the tachometer drops to zero and the glow plug light comes on. Anyone else have a similar issue? I just want to make sure I’m swapping out the correct part lol. I’ve checked VCDS and it doesn’t seem to be throwing the code many have mentioned. I appreciate any help and and thank you for the video and the information within.
My 03 beetle is doing the no crank thing and I hope this is the answer.. thank you for the video!
Probably air leak in fuel line or injection pump.
So I have a 2013 Passat tdi 6 spd manual. Once in a while after driving my car I go into a store come out and try to start it and it just cranks over. I sometimes have to let the car sit for 20-30 mins before it starts and I can drive. This doesn’t happen all the time only randomly. Also when the car is on a cold start and I start driving it bucks a little like it wants to take off. Do you think it could be the crank sensor failing? Ps no codes! Thanks so much
Thank you. This is awesome 👍👍👍👍
Cheers Michael
Mate.... thank you so much!
Thank you sir you are a flamin legend
HELLO I changed my clutch soliniod and disconnected battery ..now won't even crank .any Ideas .thank forthe great video
You are Good could do with you in Letterkenny area of Donegal
Nice diagnosis mate & good details 😊
Thanks mate 🙏
Like your videos, very helpful. Question, on your crank sensor VW 1.9 TDI 2001, both outer terminals are negative. What might be the best place for me to start looking I have no positive terminal
Nice analysis Gerard!
Cheers mate 🙏👌
Hi mate, great video! I unplugged the sensor and it still just turns over BUT sound as if it’s about to start any minute whereas when the sensor is plugged in it has no interest at all. Any ideas? I think best thing is to re-time it from scratch?
If you have a lift pump, make sure it is providing pressure.
Very informative vidio I am having a simuler problem with intermittent start up plus oil light sensor showing after new sensor fitted and an oil change help
Skoda yeti 4x4 140 bhp
Nice video lesson
I tried unplugging the crank sensor no luck. *correction* I tried again and the engine started without the sensor! Car is running 08 Touran 1.9 tdi 364000kms. Thanks!
Good job
In my fule pump only 0.50v electric going, it should be 12v, where will be the problem?
Do u know where is inertia switch? ( Fule safety button)
Nice process.
Thanks
boss am from aferica ethiopia nice video
You work nice man,vw power 4rom South Africa
Thanks Melusi
Hi, I have a 2.0 bkd engine, it starts really slow in the morning. I changed the battery, injector orings and glow plugs, but still starts really slow in the morning, after 2 cranks.
Hi mate could you advice me got a vw touran 2008 1.6 fsi
Reverse lights stoped working 2 daysbago yesturday the headlights comes on with ignition while headlamps relay switch is off today the car wont start any advice would be very appreciated
Changed the h switch still no difference checked fuses wirh probe they seem ok
Thanks for this vidéo ,what is value torsion?
Bonus just got my golf 1.9tdi BLS engine and it starts after a while noticed cam sensor not plugged in properly she just had full cam belt kit I'll test loom and look for signs as befor this she would fire straight up
My 2002 ML270 cdi has the same problem. Replaced the cam shaft sensor position sensor, the Crank sensor and it still won’t start!
Good explanation 👏
Thank you
Hello Gerard! Have you thought that VW stated to name their engine line as TDI in about 1992, so neither engine code, no even fuel injection system in your video's name...
Thank you so much you really help me sir
very useful and informative video. My question to you is how can l determine on a five pin connector vw golf mk6 1.6 tdi.
which pins relate to +5v and _5v on the air intake swirl valve motor. Not easy to find access to a wiring diagram for this.
As l suspect the swirl motor and wish to see if it functions on the bench

Well explained and easy understandable. Thanks sure did help
Would this be the same on a 2.0 gas engine, for a 2000 golf?
Where do you find the figures for signal and power, shop manual?
U0155 error code for my passat cc 2012. I have changed the battery 🔋 but still same problem in the morning juste??
Thanks for this video.
Does anyone know the correct torsion value for a BLS engine code 1.9 TDI in a 2008 Audi A3.
I have searched but nothing conclusive.
Many thanks
Thankyou maestro 😘😘
Can this be a problem for hot start hessitation?
Hi Gerard thank you for sharing this video, Ive got a vw mk5 1.9tdi in the mornings it wont start i have to use starter spray then for rest of the day starting is fine... can you pinpoint me to a rite direction ? Any help would be well appreciated.
never use starting spray on a diesel, you could bend a con-rod!
I have a 2.0 pd, cut out, won’t run, gravity fed the flow to tandem pump, and vacuum can on the return, I can’t get anything back from the return cranking or not, therefore no flow to the injectors. Do the tandem pumps fail like this???
Hello and congratulation for this video. I have same problem with my Caddy, year 2010 , 1.9 TDI, 77kw, 2k ACBLSX01 engine. All the symbols appear on the board when I turn on the ignition, in this case I have excluded some releys. Like in this video I disconected the sensor but engine it still won't start. Could you give me another suggestions please? I'm not mechanical but some timebut I like to solve problems myself . Thank you I don't know if it helps but the engine has 108,000 real km on it.
Brilliant video well explained good work 👍
Nice systematic diagnosis there. Could it still be a camshaft issue if the fault is intermittent? I've got a 2 litre tai Passat 2011 B7 that does this intermittently.
I'm having the same intermitent problem on my 2010 2.0T EOS
So will it make it out of time if u loosen the bolts
Thank youu brother I found my clue
nice tip
Nice 👌 Top presentation 🍻
Cheers Mike 🍻
My mk6 2010 model jerks before takeoff when i accelerate
Hello there I have Signal on Pin 1 (4v) Pin 2 (3v) Pin 3 Is ground and my Caddy still doesn’t start but it does start with the camshaft sensor disconnected I put a new one in and still doesn’t starts
I hope you do more Volkswagen TDI diesel engines. I have one that starts sometimes... sometimes it don't. Come back the next day and it will start. LOL Beats me....
My wife is about to scream. LOL
@@Lee-eu6wf Thinking I may have the solution... EGR valve LOL
