I pulled out the rear brake light module and tested the lights with someone in the car hitting the brake and it worked fine. Then all of a sudden I will be driving and the failure light comes on again. Is this a fuse issue, light bulb issue, electrical issue? I hate taking the car to the dealer so any insight would be great. thanks!
I had the same issue with my '07 335I. It took a few trips to the dealer before it was solved.
