Hello together, I drive a Slk r171 200 compressor problem During the ride all the indicator lights went on and in the display appeared a red battery the engine did not go out you felt a slight jerk and the lights went out again. The next morning he did not jump on and the fan for the cooler ran at full speed the starter says no muck. Battery I renewed but no improvement of the same behavior. Does anyone know what it could be ? Am for every hinw Eis grateful. Greetings Ulli
