Afternoon,

 

I've had a bit of a weird issue, basically when the lights are off, or I've got only my sidelights on the  bulb warning lights comes on the dash. But when the main beam is on all is well and the light goes back out, and when I turn the lights off it comes back on. I've checked the bulbs and everything is fine and working. My car has factory fitted Xenons.

 

So I've taken it to a local specialist who's gone over it twice checked the wiring etc. tried new xenon bulbs with no resolution. The next step they say is to change the ignitors which they've quoted £550 as it's a specialist part that has to be ordered from Germany.  To rule it out I want to try some second hand units or new units, ideally Hella but would consider others but I don't want too much hassle fitting them. Does anyone know what I should be looking for or have part numbers? I've checked on here and from reading the ignitors and ballasts are integrated in the same unit, but I just want to confirm that as well. 

 

Or if you have other ideas let me know. Any help would be greatly appreciated. 

I had the same issue with mine, turned out on the first occasion to be a worn out brake light bulb, so replaced the lot. The second time it was down to the auto levelling motor not working on one headlamp. I found out it was the headlight connector not fitted on correctly. I would try removing and refitting the headlight connectors, then remove the light unit and unplug the motor (this can be done with the light in place but is difficult) test the voltages to the motor on both sides and they should be the same

you could always disable the lights out warning system via vcds as a last resort. I dont know how but ive been told it can be done
