Hello dear Lupo – connoisseurs. I’ve had the problem for a few days that my motor control light suddenly lights up. Unusual changes, already long before, were unusually high speeds at warm- just like at cold start, which have normalized after about 30 seconds. ( ca. 2000 rpm. ) Sporadic. I could and can delete the lamp by disconnecting the battery, 5 minutes waiting time and again clamping. After about 60 km the whole thing repeated itself, and now it lights up again after about 60 km. My workshop appointment is only next Friday to read out the fault memory. But maybe you already have ideas, which according to the special behaviors of the lamp could be. Simple deletion – Let the lamp by disconnecting the battery, sporadic turning up the engine at start…… Greeting Jörch
