When you say headlight adjustment, do you mean the manual adjustment screws or something related to the auto-leveling system? Did you have an error message, or just a visual symptom? Did the light intensity change? Any details are appreciated.

I meant the auto-leveling system and the error message was the same as yours. I'm not an expert, but if unsure, get it checked by a mechanic for a proper diagnosis.

I inspected the electrical connectors and found corrosion. After cleaning, the auto-leveling seems fine, and the error message is gone. The servomotor seems okay. I'll still have it checked at a workshop to be certain.

I had a similar issue on my GLK where the headlights pointed all over the place. It was a problem with the headlight adjustment. Check if yours are aligned before replacing parts. Did your light intensity also change?
