Headlight driving me crazy

rockit2 · 11-14-2018, 12:57 PM

well I need some guidance, my low beam and high beam does not work on the adaptive xenon lights. So I purchased new low beam bulbs from ebay but they did not work. could it be the ballast or is there a single point that I can replace since the high beams also do not work. This is a situation as I get off work at night and needed to use this car for the next month as my daily . It seems I have had a long run of bad luck with this X3 but I still love it lol

These cars do not have low/high beam bulbs. It's only one bulb.

What exactly is the issue you're having?

thanks for the info , xenon does not work on both sides but halos work and fogs work fine and does daytime running lights work perfect just no xenon low or hi beam

I find it unlikely that both ballasts have burnt, if you already replaced the bulbs and it still doesn't work.

I would check for a blown headlight fuse, it must be blown.

After the fuse I would diagnose the FRM.

Checked the fuse?
