Peugeot 1007 Headlight Range Control Fault

I had a similar experience with my old Volvo; the symptoms sound eerily alike. The auto-leveling system went completely haywire after just a minor fender-bender. Does the headlight switch seem to be working properly, and have you checked the light intensity yourself? It sounds like a defective servomotor and, it's not fun when your beams start doing their own dance.

Thank you for the quick response! I did check the headlight switch; it seems responsive, but doesn't seem to change much, and I tried adjusting manually, but same issue. You mentioned a servomotor—is that something I can easily check myself, or is it best left to professionals? I'm moderately handy, but definitely not a mechanic.

I'd advise against amateur surgery. These systems can be surprisingly complex. In my case, the control system was completely fried, and it took a specialist to diagnose it properly. By the sounds of things (warning light/error message), I think it is highly likely that the servomotor is the issue. Best to go to the workshop.

Much appreciated! I was hoping to avoid the workshop, but it seems like that's the most prudent course of action. I took it to the shop, they came to exactly the same conclusion, as you. Defective servomotor in the headlight. Repair cost: 1040€. I wish it was less, but at least I can get it fixed.
