You've got my interest.
So just to be clear, you went from halogens to OEM bixenons, right? I have LCI halogens and am going to retrofit OEM non-adaptive xenons and LCI HIGH tails.
Have you followed the BMW instructions? I guess you haven't bought the BMW retrofit kit - it comes with all the wires, sensors, xenon control units, D1S lamps and other things.
If you want to, make a thread. It's not for me only.
