I was going to create a new thread but thought I would update this one instead. I believe there may be a way to do this for 2015-17 vehicles. After studying the wiring diagrams, it may be possible to tap into the driver door lock motor wire (Blue-Green) near connector C465 (pin 36) at the LH "C" pillar. By running a wire from here, through a diode, and connecting to the Grey-Brown wire coming from connector C311 (pin 2) under the driver's seat, it would provide a remote input to the Driver's Door Module (DDM) to fold/unfold the power mirrors.
If I'm reading the diagrams correctly, whenever you use the keypad or the remote to lock the doors, a 12V pulse will appear on the Blue-Green wire at connector C465, pin 36. The same thing will happen if you enter the code on the keypad or use the remote to unlock the doors, but current will be flowing in the opposite direction. Either way, tapping this wire will provide a brief 12V pulse during remote lock and unlock. Connecting this pulse to the power fold input on the DDM (via an isolating diode) should cause the mirrors to fold/unfold automatically during remote lock/unlock.
There is, however, a caveat to this approach: If the mirrors are folded, the next input from the fold switch causes them to unfold. Thus, if you were to fold the mirrors yourself using the switch before you locked the vehicle, they would then unfold as soon as you locked the door with the remote or keypad. If you then unlock the door, the mirrors would fold! You'd have to "re-synch" the mirrors by activating the switch manually to unfold them. Then, you could lock the doors again.
Coming up with some sort of "smart" control that takes into account if the mirrors are already folded would require a more sophisticated solution.
EDIT: It's also possible that tapping the blue-green wire would fold/unfold the mirrors if locking/unlocking the doors with the door lock switch which may not be desirable.
This is an interesting solution to the problem... as long as you don't turn on auto-lock. Otherwise, if you turn on auto-lock, you'll get another pulse to the mirror fold input and they'll fold again when you put the Expy in gear and start down the road.
Also, every time you manually lock/unlock the doors via the door buttons inside the car, your mirrors will move again.
