I have a 2000 E39 and when I step on the brakes the lights flicker for a quick sec then normal. When this is happening I notice that all my lights have a very slight constant flicker. This doesn't happen all the time. It's very random, and sometimes I can turn the car off and restart, and it's fine. Any body with similar issues or have any idea how to fix this? Alternator, LCM, GM...?
Thanks in advance for the help :-)
