Hi,
While this topic about low beam problem maybe you will have any ideas about my problem.
Mine 2007 e91 (with original addaptive xenons) has left side dipped beam fault, also there are cornering system fault.
Dipped beam is not working on left side, but when i tried to turn on headlights over INPA both side dipped beam worked fine. Checked the fault codes on INPA, there are error code for "StepperMotorBox" (error: 9CBF). Could this error cause not only cornering fault, but also not letting left dipped beam to light on when light switch is on "Auto" position?
I will change left side headlamp vertical control unit (as diagnostic tools pulls me this error), but I'm concerned that light is not working, and only works over INPA in bulb test mode.
Maybe someone had this issue? :/
