Adaptive headlights adjustment?
My 2011 M3 has Xenon Adaptive headlights with auto-leveling, and I recently noticed an adjustment knob/screw, but I don't know it's purpose. In the attached photos, what is the purpose of the knurled adjustment knob/screw? Does this adjust the headlight position ? If not, is it possible to adjust the height of adaptive headlights? I've read conflicting things in threads about adaptive headlights.
