I did a search and found this thread. My wife's 2007 X5 4.8 has had the High Battery Drain error message a 1/2 dozen times or so. She drives it every day, so no parked in the garage unlocked without being driven possibility. Is this a known issue? Is there a dealer fix? Our dealer just blew off her complaints about this issue.
