i have Auto Mirrors on my other car. Not a Y62. it has a button on the drivers door that allows me to Manually fold them in, Auto, and Off. if i have them set to anything other than Auto they do not move. They unfold as i walk u to the car and the key gets to within range. they fold in when i lock the car. Easy to check if the car is locked from a distance by how the mirrors are sitting.

The mirrors also tilt down when i put the car into reverse, only when they are set to Auto though. See if you have a button
