My wife has had many starting problems with her 1999 VW GTI VR6. The problems starting seem to be after driving for a while and then letting the car sit. Plus, when the starting problem usually pop up when it's hot (+ 90 degrees). There have been stalling problems where the car seems to loose electrical power then shut down.
We took the car to a trusted garage and they can find no problems. Can anyone speculate on the problem or has anyone had similar problems?
