I am experiencing a loss of power on hills and when trying to accelerate an intermitant check engine light appears. I own a VW Jetta tdi 2000. The dealer diagnosed the problem 1st as a turbo control module, $252. Some increase in power but not very much, check engine light off. 2nd trip to dealer after an 1-1/2 hour discussion about charging me another diagnostic fee and my consenting the problem was diagnosed as carbon in intake and egr valve replacement. I asked 4 questions :how does carbon get in an air intake", how did the technician determine this was problem? why wasn't it identified the 1st time I took car in and what guarantee would I get" the dealer would not or could not answer these questions and the customer service rep at VW America has not answered them but has offered to pay 100% parts and labor for the repair after two days of calling and trying to get an answer from both of them. Don, is the customer service rep who offered to pay for repair upon my going to another dealer and paying for another diagnostic to verify the problem, as the first dealer has refused service to the vehicle because I insisted on answers to my questions before ok'ing repair. The number I called for VW America is 1-800- 822-8987. I have about 81,000 miles on the car and this problem creates a serious saftey hazard on the interstate or any highway where a slow moving vehicle may be a hazard.
