Beware of idrive battery drain
I noticed every once in a while that Blackberry would be slow to start. I took her into dealer for battery check and some other maintenance as she's coming up on 50K miles. They found that while at rest...she was being woken up way too many times due to the controller for the idrive causing excessive battery drain. They replaced the con module and the battery and everything is ok now. I didn't even know the idrive controller was supposed to light up.
OAN...when I went to pick her up I test drove a 2011 M3 E93....OMG!
