Good evening, I have a 2008 V8 and I’m actually very satisfied (laughing after only my old V10). However, I have recently the problem that my ACC fails after 1 minute. In the display ACC error. Was already in the workshop to read out the error memory. Entry (similar wording): Electromagnetic interference. The employee at the friendly was also surprised and didn’t know what it was. Now I have an appointment soon, because the error occurs again and again. What still occurred to me, and he did not do that before. Every time I restart the car and leave as soon as I meet a vehicle, the display “ACC off” shows even though it is turned off. Does anyone have an idea what that can be? Greeting Markus
