Hello. I have "save seat and mirror settings at last setting" checked in iDrive in my 2015 228i Coupe. Yesterday I had regular dealer maintenance and the technician moved the driver's seat and mirror. I think I made a mistake, getting the car back, by first locking the car with the comfort access fob, reopening it and pressing my memory setting button to return my settings, since my memory settings got erased. Be careful about this. Do not lock the car after someone else changes your seat/ mirror settings if you have the "save last driver seating/mirror setting" checked in iDrive!
