I just recently bought my 2004 530i six months ago. Everything was working then suddenly a couple days ago my headlights does want to work correctly. Sometime it doesn't want to cut on and sometime passenger side comes on so I have to play with the Multi Function Switch or Headlamp Control Module for both of it to work. But when I switch the control off and back on the light driver side turns on and the passenger turn off. Can someone please help
