I have a 98 M3 coupe - ASC light flashes at 70-75 MPH, dry pavement, driving in a straight line, no wheel slip at all. Dealership replaced ACS throttle potentiometer. Mechanic said 50-50 chance that potentiometer or something else could be the problem. (Fault code apparently pointed at 2 possible sources of problem.) Replacement no help - in fact, worsened.
Bentley manual useless on this option. What are other possible sources of this problem?
