i bought a used adaptive bi-xenon off ebay (shame on me) to replace a damaged one. At first only the headlight would work. Swapped over the controller from my good light unit and the shutter for high beam now works also, as well as the levelling, but the LED drl's still dont work. I've swapped the LED modules from the good one, at least the two halo ones as the eyebrow one isnt interchangeable, but they still dont work. Any thoughts?
