Since you have a warning light on, the quickest way to identify the failure point would be with a code reader.
I have heard the stepper motors themselves are unreliable, but I have not seen a separate part number for them. Sometimes they become detached from the ball joint, but that usually wouldn't throw a code.
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. |
My adaptive feature failed recently after experiencing TONS of condensation in the housing.
I was going to bring it in to bm to have the whole unit replaced but I got new ballast and replaced a few things in there... I'll post pics of what I did when i get home from work
