    Steve,

    I've had this issue on my 1999 550. It turned out to be the AC compressor leaking oil onto it's electromagnetic clutch's winding. As a result the winding's isolation dissolves and you have a short circuit. The compressor's front seal is the culprit and it can be replaced, but I chose to get a new compressor.
    The oil also drips on the alternator, and you should see a few drops directly under it on the belly pan. This could eventually damage the alternator.
