Just because the alternator and battery have been replaced does not mean they are good and working properly.
You have a problem with the Rain Sensing Wipers and the iDrive/Radio all at the same time. Seems a bit like there may a relationship.
I have found the E70 does not notify the driver of a problem with the charging system under a few driving conditions.
I run an Ultra Gauge with alarm thresholds for Voltage and in the past few months on a few occasions I have had my Ultra Gauge alarm that there was Low Voltage. I had no charging what so ever for a number of miles until I pull over and shut the engine off and restarted the vehicle.
No warning of a no charging situation on the vehicle.
