“Seat Symmetry” / “Moving Passenger Seat with Driver Controls”

Enabled in the MMI menu , not working when you try to adjust the passenger seat with the drivers seat buttons , the passenger seat does not move , and the drivers seat buttons do not adjust the drivers seat, this is correct, so I’m assuming I need the passenger seat memory module. ( I only have the driver seat memory module).

“Convenience Side View”

when selected this moves the passenger seat back to give clearer vision ,should the passenger seat be obstructing the Drivers view from the passenger window. anyone worked out the coding for this?
This was in Audi A8’s and A5’s see pics
