1998 audi a4 2.8 - driving along highway, in 7 degree temp, car started accelerating ( feels like it is driving itself) even after foot was removed from pedal and full force had to be applied to brake to stop the car at which point it went into high rev and engine was immediately turned off. Mechanic could find nothing wrong. This car also had 2 similar incident (once when new) and once a number of years ago. After much back and forth with audi, they took the car in, and said they could find nothing wrong. As a precaution I had the cruise control disconnected and the throttle body cable replaced so felt the car was safe. (all at my expense)

What owners say
1. Heated seat burned through the leather burning the back of my leg when on the lowest setting(1/6). 2. The cruise control works about 1% of the time and will engage unexpectedly if not turned off.
I have a 1998 audi a4 avant, 2.8 v6, manual transmission. After 45k miles the cruise control module ("brain") failed and had to be replaced. At 91k miles the ABS brain failed. Was there, or will there be, a recall on these items?
Normal driving conditions, no modifications to vehicle, at 80k miles the anti lock brake module fails and the ABS no longer works. The brakes are prone to locking up. The replacement part for the vehicle when out of warranty is $1200. I have been driving it as little as possible until I can save for the repair. Additionally, the cruise control stopped working out of the blue at 55k miles. This module has not been replaced either due to cost.
Cruise control inoperative.during high speed braking car shimmies and hops. Problem began after serviced by audi as per audi brake recall. In the last 12 months my audi has spent 2 months at the dealership for repairs. This vehicle is a lemon.
Bolt for cruise control servo fell out resulting in servo becoming wedged in engine area and causing sudden acceleration of the vehicle on highway. Yh
