If the fuses are OK, check the socket that attaches to the bulb. Just jiggle it to see if the light flickers. Since only one light is going out (if pass stands for passenger) I would suspect a short first. Does your check system tell you a low beam is out?
The reason I would check this socket is I just replaced one. They are cheap and at any parts store. If this would be your problem be sure to use heat shrink wire cover or some other weather proof connector.
Hope this helps, Jim
Thank You Jake I will Check that out and let you know what happened......
Check the small fuses along the upper rim of the fuse box (they are about 29 fuses ranging from 7.5A, 30A, 15A, 10A) See if those are working properly. Refer to the BMW car manual, or lid of the fuse box to find the fuse(s) that control the low beams and/or headlights.
Also check the Mustard Colored relay within the fuse box (it is a cubed shaped fuse located toward the lower right of the fuse box, it has a mustard-yellow color)
When doing this make sure that each fuse or relay mentioned is clean and in good working order. If not buy cleaning material or replace the bad fuse or relay. (either BMW or your mechanic should care these fuses or relays, which you can buy and replace yourself)
And finally check (if possible) the LKM box (black retangular box labeled LKM, located at the bottom of the fuse box) Make sure that is in good working order.
If all else fails recheck the light bulbs or have your car serviced by a mechanic who knows alot about electrical problems and configuration in BMWs.
I hope I helped you...Good Luck and keep this forum updated. ***JAKE***
