After spending a bit of quality time with my service advisor today I found out:


1. my build is not eligible for the extended warranty,


2. there is an igniter module for the xenon bulbs that fails at times and the BMW techs swap them L to R to check what is wrong. Part number is 63117182520


I did not realize there was a control module on the head light for the D1S but studying pictures of used headlights on Ebay and then going back to RealOEM I can see it is strapped to the bottom of the headlight unit. This weekend I will remove the passenger side wheel well liner and see if I can get this item out. With a bit of luck this should be a fairly easy fix (knock on wood.....). Worst case the bottom bumper cover has to come off and loosen the front of the fender.
