I recently bought a used 2013 335is . It was not until it had got dark and I was over 100 miles from the dealership that I realized that the headlights were not working properly . All of the lights on the car work including the halos and parking lights just not the xenons . I have been searching the forums trying various solutions and have already tried replacing the bulbs and the ballast . The previous owner has installed after market halos and clearly has done some coding . I'm suspecting that this could be some kind of coding gone wrong . Any help is appreciated . Thanks

Thanks, I copied this post to the lighting sub. Not sure how to delete this one.

Reset the short circuit counter. If that doesn't work, then perhaps replace the ballast or the bulbs - maybe both.

You can reset the short circuit counter using tools 32 or bimmer geeks app
