It's likely to be your rear headlight level sensor located in the rear driver side. Refer to part 2, 6, and 7 from the diagram below.
The sensor attaches to the lower camber arm, which is also where the spring sits on. This sensor can be seated wrong during reinstallation which causes the car to think the rear is sitting very high compared to the front, therefore aims the headlight up like crazy.
The follow images are based off the E90 M3 but it is identical to our F30.
The Wrong Way
The Right Way
The Fix:
- Jack up the driver rear side
- Undo the bolt that holds the rear sensor to the lower camber arm.
- Reseat the leveling rod to the correct orientation
- Redo the bolt.
- Put your car back down and try the headlights now.
- If it doesn't work, your rear sensor is probably broken.
Hope this helps guys! Good luck! |
Exactly that was the problem.
I actually got it fixed already at the dealer. They mentioned exactly the same thing.
Thank you for all the explanation and pictures.
It will definitely help those who run into same problem.
