I believe this is the coding
Select STG 52 (Beifahr Türelektr..)
STG long coding -> function 07
byte 04
enable Bit 2
enable Bit 3
Select STG 09 (vehicle power)
STG access authorization -> Function 16
Enter unlock code 31347
STG adjustment -> function 10
select (15) Access control 2 level reduction at Rueckwaertsfahrt
Value to active (active) put
also possible: Show menu item in the radio / navigation system, so you are even able in the future to activate the function on or off
Select (20) Access control 2-menu control level lowered
Set value to active (active)
For some cars when the mirror returns from dip after driving it doesn’t fully return, this depends on a memory module on the door controller being present, there is a way to check this but unsure exactly.
May be similar in OBD Eleven to this:

Getting android phones at work shortly so will be ordering obd11 when I get my hands on one.
