Full Beam Problem! HELP?

Asked by Jun 17, 2019 at 05:02 AM about the 2011 BMW 1 Series

Question type: Maintenance & Repair

lights. I will be driving along and suddenly the full beams will come on and I
can't turn them off. This happens in the day and at night and this has never
happened in the past year or so that I have owned the car. I am able to flash
the lights off but as soon as I let go of the lever they come back on. The only
way I can drive without my full beams is to have the lights off completely. A
few days later the full beams were coming on every time I indicated but on
this occasion I could turn them off. These issues keep occurring and full
beams seem to have a mind of their own. Can anyone diagnose the
