When I got to work (about 10 minutes later) I parked in the garage and shut off the car for a moment. When I turned it back on, it started fine, but after a few seconds the "!" icon appeared again and it said "high battery drain" on the iDrive screen.
It's a 2004 530i. I just got it yesterday, and I don't recall seeing the warning at all until this morning. It sat overnight (obviously). My drive into work is about 35 minutes, so I don't know how long the warning was there because I didn't notice it until about 25 minutes in.
Has anyone seen this before?
any after market electrical add ons may cause high drain if not installed properly, that would be a good start as well as checking the battery itself and how well it holds a charge.
