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***
