same here...it was a b***h to get that leveling arm apart from the headlight housing..now my lights "jitter" when they go through the initial level upon startup and something seems to have gotten stuck

it's a pretty straightforward diy and relatively easy. I followed this DIY http://forum.e46fanatics.com/showthr...79#post8554679

I also cleaned the projector lens while I had everything apart which was extremely dirty

the projector bowl was kinda cloudy too

Running into the same issue on the passenger side. So, is it a definite answer that it's a faulty igniter? Mine is 2001, so 11 years old now.

About a month ago, my drivers side light blinked out. I thought it was the bulb but after further research, I realized it's most likely not the bulb. When I turn on my headlights, they'll both be on. After a minute or so, the drivers side gets brighter for a millisecond, then it goes out. If I turn the lights off for a few seconds, both headlights will come back on, then the drivers side will go out again. I'm pretty sure the ballast is bad. I didn't really want to get into switching ballasts and igniters from side to side to diagnose. I'm hoping for a plug n play solution. As a solution, I ordered a used OEM ballast and ignitor from fleabay. As soon as I get it installed, I'll post my results.

yeah mine was doing a similar thing, but after researching i think that it is the igniter, not the ballast.

Idk if this even makes sense but I have had the same problem in my 2000 323ci, I've actually noticed that they will go out on start up or while driving but I've also noticed that while cornering they will go out...? If I'm cornering hard left the passenger side will go out and visa versa for the driver side? Has anyone else noticed this as a problem, I've checked all connections and no corrosion so I guess I'll just have to start replacing parts.

Ok. So after taking the headlight completely apart, I plugged the light in with the "new" ballast and igniter and the light blinked out again. I happened to have bought new ds2 bulbs, plugged a new one in and it worked. Turns out the bulb was bad. I didn't know that hid bulbs could appear to be working sporadically. Oh well. Now I have a spare working ballast and igniter, intimate knowledge of the inner workings of a BMW headlight and a reason to buy some new clear corners. That's a whole other story. BTW, it really is a PITA to remove and replace the igniter.

The moral of this story is to diagnose the problem first before throwing parts at it but isn't that how we learn?

Try this:

I also found a video but I can't find it right now.

Do you have headlight washers? They have to be removed in order to remove the headlights. Then after you have the headlights out, he most difficult part is uncoupling the xenon adjuster.

Intermittent headlight issue

I have a 2001 325I with the same problem - intermittent outage of (passenger side) xenon headlight. The headlight comes back on when switch is cycled, and outages become more frequent in cold weather (now!). From the two pages of this two-year thread, it appears the consensus is that the culprit is probably a bad ignitor(s), although old bulb and/or old ballast could be issue(s). Please confirm this summary is accurate, and advise on your finding, 217Bimmer.

swap the bulbs first!!! i tried reading and thought i had done the bulb swap right, but i am an idiot and the problem was with the low beams, not my high beams, which are halogen, so my bulb swap was worthless. because i swapped the wrong bulbs the problem remained on the same side and i thought that it must be the igniter. i bought one and swapped it out and the problem wasn't fixed, so i ordered new xenon bulbs.

swapping the xenon bulbs is much easier!!! just the 4 bolts and a trim clip to slide out the headlight. still a pain in the ass just for a headlight, but do that first because the igniter is a true pain in the ass and you might break something like i did with the leveling screws.

Thanks very much! I will try replacing the Xenon bulb first. Do you order from Pelican Parts, or are these available at local parts sotres (Advance, Auto Zone, etc)? Thanks!

Xenon front headlight failure - intermittent, both lights

I've been having the same issues as all of you since I've owned the car. Where did everyone purchase their igniter from and what DIY did you guys use?

After this weekend I may have an igniter for you if you need the more expensive one. New online are like $300.

Also, first I would swap your bulbs!!! Do this first to make sure that the issue stays on the same side and is not just a failing bulb
