Here is my strange issue with my 2001 E53...
About a week ago I noticed that the brake lights were constantly on when the ignition was on. I drove for a bit and about an hour later I got the speed sensor/ABS module trifecta (ABS/Traction control/yellow brake) lights on the instrument cluster. I can't find any indication that the 2 issues could be linked but I'm not sure.
Now tonight I am getting random "bulb out" lights on the instrument panel. It shows either one or 2 rear lights out. This leads me to believe it could be the light control module and the trifecta is just a coincidence in timing. I also tried pulling the fuse for the brake lights but they stayed on
Tomorrow I will try and trouble shoot the brake light switch and the ABS module. Its a bit cold working in the driveway at -25 so I just got access to the brake switch today.
Any thoughts? Thanks a lot, Mike
