Sorry to bring this thread back up but I came across the following from an Audi forum...
Enabling reverse mirror tilt on cars without memory seats:
Go to module 52 Door Elect, Pass., Long Coding, Byte 4. If the byte has value 40 (cars without electrically folding mirrors), change it to 4C. If the byte has value 50 (cars with folding or folding/dimming mirrors), change it to 5C. Afterwards when reversing and the mirror knob is in passenger position the passenger side mirror will tilt while on reverse to better show the curb. Without memory seats it is currently not known if the tilt can be adjusted, it seems to default to a standard amount according to reports (see links below, thanks to EuroDan and Unisurfer). It was reported by -V- (here in Finnish:

This probably has to do with equipment levels. Ross-Tech has updated their VCDS/VAG-COM software data to include relevant bits with descriptions, so you can more easily try different combinations.
Its detailed on:

Not had chance to investigate this but its worth a shot!
Will have a chance to play next weekend unless someone gets there first!
