I am getting a display "-124d" code on my 2005 MB ML350. What does this mean? Minor or major?
Hmm, can't find this one on the list of fault codes. Closest I can find is P0124 Throttle/Pedal Position Sensor/Switch A Circuit Intermittent. Does that sound plausible? How about checking the connector on top of the throttle position sensor? In my car it would be very difficult to kick it loose, but maybe the connector is more accessible in your car?
