hi, this would have to be a wiring short somewhere or a problem with the footwell module itself.

I would consider moving the headlight over to the other side and holding it in place to be 100% sure that the issue is not with the ballast or bulb. then start looking to the wiring.

moved to other side still does not work could it be high voltage cable or one of the other wires in it? I put another new bulb in it again to make sure that was not it and it has new ballast also
BMW Mechanic: Steve, BMW Expert replied 3 years ago
