I purchased a 01 Volkswagen Jetta in July of 04 and in les than a month it began to stall as I was driving, so I pulled over and it could not start again. I got it towed was told it was my battery and got that replaced, then it happened again a few months later and I was told it was my alternator and got that changed. A few month ago the car would not start again, I was told it was my sensors and got that changed, within 2 months it has happened about 6 times and I've had 3 diagnostic tests that reveal nothing is wrong with the car. I don't know what else to do, al least if I know what the problem is I can fix it. But my car keeps refusing to start( for hours at a time) and everyone tells me the car is ok.
