Thanks for your reply-It happens that the guy who did the belts was the guy who had the car. He has had it for over a week and not been able to figure out the problem other than saying "we think the injector pump needs to be recalibrated", but doing nothing because he didn't know how to do it. SO I took the car elsewhere. They were pissed-but too bad! The new guy comes highly recommended and is a certified diesel mechanic. He has resolved similar problems with other VW bugs which he says was resolved by re-calibrations of the injector pump. But they are checking it out. I feel much better since taking it back from the other guy. However, what a OX(&*$# jerk -the interior of the car is covered in grease and will need a major scrubbing.
On a happier note-I would like to take a minute to say I love the VW Bug TDI. In fact I just purchased a 2010 Audi A3 TDI. It is awesome. I could not bear to part with the VW TDI Bug especially since the dealer was not giving much on trade in and my son can use it instead of his truck (also a diesel). I love the TDI's however, maintance and repair work has been a real nite mare here in South Florida. Even the VW dealership has been a nite mare. It will be sometime before I need anyone to work on the Audi other than service. Hopefully I have found a decent diesel mechanic for the VW.
THANKS FOR YOUR ADVICE-I will keep it in mind.
