I would think it would partly be responsible due to battery registration. AGM batteries need to be registered in order for the alternator to properly deliver the correct charge, or overcharging can occur - venting the battery and destroying the cells in the process. This will become more critical as our M3s get older.
Auxiliary power within the cabin is cut off after 35min due to IBS, however this doesn't account for a possible failing control module that can keep CAN or MOST devices alive within the vehicle.
