I think there has to be a software issue, in which the car is not going to sleep correctly, and their is a drain on the battery. Some have suggested that the remote is too close to teh vehicle and this keeps the battery awake. Never had that issue with 30 other cars with a remote.
Might need to lock car to shut everything down, even if 2 push to shut off, locking my car is not a habit I am use to doing, since it is parked in my garage.
As I am finding out, BMW is unique, and unlike any car I've ever owned..
