I know i have asked this before but maybe more people can help me out this time




Hey I have a bi-xenon failure. My car is a 2005 X5. My car does have the adaptive headlight system(lights turn, when you turn)

The problem is: My passenger side projector at first, I noticed got stuck in one position, as in, the projector was pointed towards one side and would not move. I tried to correct it by playing with the turning knobs to correct it, but that did not work.

I left it like that, thinking I was going to get it fixed. Then a week later that same passenger side xenon went out!

Now my question is, if it was the adaptive light control module broke because of the projector being pointed one direction without moving, would that cause the light itself to go out? Or would it simply stop the function of the projector turning

OR did my actual xenon control unit(ballast) just break and that’s what I have to replace.


I know that my bulb is fine because I checked it on the driver’s side and it worked. Same with my igniter, I swapped the igniter from passenger side to driver side and it worked fine as well.

So its either the adaptive light control module or the actual xenon control unit (ballast)

What do you guys think?

Help me out please J
