Thanks! How did you figure out it was the servomotor? And did you notice any issues with light intensity?

Well, I didn't figure it out myself. I took it to a workshop. They said it's a common problem. I didn't notice any light intensity changes, just the beam direction was off.

Okay, thanks! I'll take it to a workshop then. I appreciate the help! Turns out it was exactly as you said, the servomotor. Cost me 1040€ to repair.

Hey, I had a very similar issue with my i40. Is it possibly a defective servomotor in the headlight? Check the lighting system and electrical connectors too. The adaptive headlights are really sensitive.
