“I own two of the original Audi S4's, both 1993 models. My daughter was driving one of these cars in 2007 and the throttle stuck open so that the engine raced uncontrollably. She was able to put the clutch in and stop the car and turn the engine off. Then she had the car towed to the nearest repair shop. It was discovered that a plastic part on the tip of the throttle cam had broken off and as a result the throttle cabling mechanism stuck in the partially open position. …”

“I run a small repair shop and have seen a number of Audi vehicles from 1986 to 1998 which have steel gasoline lines that collect road salt and rust in the rubber support grommets attached to the chassis. The rust causes a pinhole leak which then begins to spray gasoline on the exhaust system. I have seen 5 or 6 vehicles like this in the past 5 years and saw another one last week.”
