Question about 2002 Volkswagen Jetta TDI

1 Answer

Won't start I have a 2003 Jetta Wagon TDI. I moved the car yesterday morning and it ran fine. Five hours later it wouldn't start. I replaced the battery and still won't start. It sounds like it is starting, but won't turn over and get the engine going. Any ideas on what to do next?

    Thanks for the advice. Ended up being a carbon buildup.

    Was the EGR valve and the intake manifold. I ended up having it towed to a mechanic. I had been noticing some slight hesitation on acceleration leading up to the not starting issue. Since they cleaned it out, it is starting fine and the hesitation issue is gone as well. Quite honestly, my mechanic told me that the carbon was building up 6 months ago and said I should clean it out. I never got around to it and paid for it!!!!

    am curious about what you found. Where did you find carbon build up? And why was it causing the car to not start? Does your car start okay now?

    First off your post says it's a TDI so if that is true. There are no spark plugs.

    If it is a TDI

    I do hope you had a back up power source hooked to the car before you took the battery out, because if you didn't you wiped the computer memory out and you have to have it put back in.

    Usually you have to take it to a dealer or somewhere that works on tdi's.

Check the crank sensor... easiest way to test will be to remove a plug wire from the spark plug and place close to metal on the motor ... have some 1 turn the car over while you watch the end of the wire .... you will be looking for sparks to arc to the motor ... if nothing then you will need to replace the crank sensor. if this information helps please rate it ... if that is not the problem please let me know and we will figure it out together

2003 tdi, 54 k miles, bought car new, had manifold cleaned, new glow plugs and harness. car has been driven only short commutes for 3 years. Heavy blue smoke at startup, then it clears right up. No...

valve seals are going. when car sits excess oil gets past the valve seals then when you staRT up it burns the oil off then runs fine and no more blue smoke. It is fine to run like that had the same in a dodge caravan 1996 6cyl. ran another 100 000 km. and still ran fine got rid of it for other reasons.
