Xenon bulb issue

Post by aqua0 » Wed Mar 23, 2022 10:10 am

Hi Folks,

I have xenons fitted to my 07 3.0Si and the near side has started flickering, then going off and causing a light warning on the dash. Then, it'll magically come back on again :?
What are the replacement options please?

Cheers
Never go deeper than the bottom :P

Swap left and right bulbs to see if the same happens to determine if it’s the bulb or something else. If still blinking on the near side with the offside bulb now in there, it’s either the igniter or the ballast control.

You can swap the igniters over side to side like the bulb to test those. My money is on the ballast control module under the headlight; OEM items have a vent hole that lets in water and buggers them up. Luckily they are a common part and not expensive. New control units don’t have the vent hole.

The control module OEM is almost $500.00 for just the part. You can find off brand ones for $210.00.

Someone posted on here about finding a replacement for the igniter that’s not $110.00. It’s not bmw oem. I can’t remember where they said they got it.
