I didn't realize BMW made special orange corner bulbs. That's not the issue here, it's the adaptive lights arent functioning.

If a motor has failed, and a code has been thrown, I would think the controller would be mart enough not to try and drive EITHER motor.
There is a separate ACL module that does have a part number, that is most likely the motor controller. Other than reading the code, I don't know of a simple way to determine if it is the controller or the stepper.
Unfortunately, I have not heard anyone having successfully repaired this feature without replacing the entire headlight assembly.

I'll contact BMW and see if they will read the code for me. I'm sure this is going to be cheap. What pisses me off the most is that it's 2 months out of warranty.
