Having problems with your 2002 Volkswagen Jetta TDI ?
I have a 2002 vw jetta tdi there is a warning light that is almost always blinking it looks like a coolant or temp indicator but not sure i have no manual also sometimes the car has no power what so ever it will take forever to reach 50mph then other times it runs fine. what could be my problem with car running bad and what is the warning light that flashes?
This could very well be the coolant resevoir/level sensor. if it is running poorly, these engines have a big tendency to foul up the throttle body and go from a 3" hole to about 1 1/2". if you take off the air horn to the throttle body and look inside you will be able to see what im talking about. now you can chip away at it but it must be done very carefully. dont let any fall down the intake. the proper way is to remove the manifold and let it soak. the egr is attatched to the throttle body and this is the reason for the carbon build up. also check your fuel filter. after this, it runs like a new car.
