I just picked up my MY 2001 E55 and noticed a sound coming from the rear that sounds like it might be a air compressor for the seats adjustments. The problem is that it seems to cycle every 1 second or so. Is that normal?
FYI there is a fuse panel on the end of the dash driver's side. Its a easy place to tap into a circuit for radar detector.
PS a E55 is not high enough to go over a racoon with out taking out the fog light.
