My Ride: 2005 BMW 330ci w/SMG
Xenon light out for 4 months now!

Hey fellow e46er's,

I currently own a 2005 330 coupe and my xenon headlight went out about 4 months ago and it has been the biggest pain in my arse! I really am stumped and I finally got ticketed for the light being out. I am by no means a mechanic but I have repaired a few issues with the 5 e46's I'ved owned. So once the headlight went out I did the obvious solution and replaced the bulb and got nothing. Next, I went to a BMW salvage yard and purchased a working ballast. I was sure that would fix the issue because I read that most likely is what went wrong. IT DID NOT FIX THE LIGHT! Now I'm getting really irratated with this because two fixes had not worked. I then started trouble shooting and started to swap out parts with the working light to the non working light and nothing would get the light to turn on. So now I have a headlight with a new bulb, working ballast and still is not working. I took my car in to get some major work done (oil separator CCV hoses replaced) and I asked the mechanic to take a look at the headlight and he literally said the light was "toast". I guess the wiring or something? So my question is, is their any way I can verify this? I will take any pics that could verify that the headlight is shot. I really do not want to have to buy a replacement headlight because we all know the price of that. Can anyone please help me out? I really am stuck and have one month to figure this out.
Thank you in advance.

Hey, facelift coupes suffer from burnt/damaged wiring inside of the headlight. Take out the entire headlight from the car, pop out the cover in the back and inspect all of the wires inside.

So I have the headlight out now and I popped off to covers in the back of the light assembly and the wires all look intact and not burnt out. Can anyone please help me with what to look for or something to help trouble shoot the problem?

I am definitely no expert, but I am in the process of trying to fix my headlight like you. I know you said you swapped out parts but did you swap the ignitor? According to sillieidiots stickied thread on troubleshooting that should have been the first thing to do with a facelift coupe. Btw, I have tried the first two checks, the ignitor and the bulb, but no luck. I need to check the ballast next but that means taking out the headlights and I am not a patient man
