Big Xenon Issue
I have a '14 328 and my passenger xenon started flickering and eventually went out, headlight still works. I tried replacing the xenon ballast and control module board with no luck.
So today I pulled the bumper and swapped both headlights. The headlight works fine when swapped to the driver side so it looks like it must be a wiring issue. Kinda stuck, Anyone have any suggestions how to troubleshoot from here? |

I might go EW for the engine and drive train, but that's it. OP, your best bet is an indy shop that specializes in German cars, as they're the most likely to have seen the problem before. It might even show up with a simple OBD diagnostic.

Well, at least the normal headlights work. Definitely a bummer to pull the bumper and swap the headlights just to find out They're ok. The Rheingold errors are attached if anyone has any suggestions. The wiring to the headlight looked ok, not sure how I would check the wiring between that and the fem module, seems like it wraps in with a bunch of other stuff. The fuse in the fem module forvthe headlight controller was good.
