Need help with this. This has been going on for the 3yrs I have owned my E53. Syymptom is when I turn on the ignition key with headlight in Auto. The light comes on immediately but only last 5 secs and turns off. It comes back on approximately 50 secs later. Very annoying at night. Anyone experienced this and have a fix for this issue?
