When stopping at at stop sign and trying to take off the engine seems to lose power and them all of a sudden it will make a surge and take off. When it first cranks up its slow and then it will kinda of jump and the it will run ok for a while. Have taken it to my mechanic and spent almost 500 dollars. He can't seems to find whats wrong im scared to drive it. Vw said it might be the fuel regulator and probably would be in a recall but haven't heard from them in months.
On several occasions leading up to 07-30-08, vehicle would not start properly. Vw reprogrammed keys but refused to cover costs even though vehicle was still under warranty. Around April 2009, vehicle began having problems cranking again. Vehicle would start then the engine would immediately die, but not every time. Condition got worse at the beginning of June and had the battery and alternator checked out. They were fine. On one occasion the vehicle computer gave a "steering wheel lock defective" error. Took vehicle back to dealer on 06-16-2009. This time they said steering column control module and comfort module would need to be replaced and that this problem was not related to earlier problem that should have been covered under warranty. Had vehicle repaired at different vw dealer at own cost. I kept the old parts.
