FYI the procedures and tool used to code central locking in vagcom work on our S4.

So in addition to full closure from the key fob you can have...
1. Autolock doors lock themselves over 10mph, open manually or when key is pulled.
2. Alarm Confirmation bleep (or honk) a subtle honk to confirm when you lock the alarm in activated.
3. Two touch unlock , first button squeeze unlocks drivers door only.
Second squeeze unlocks passenger doors and boot.
I have all these features on the TT and S4 enabled and was pleasantly suprised they all worked. Just follow the above procedure if you have vagcom. Or anyone passing Staines can pop over and I'll enable (or try for you)
It should work on pretty much any Audi if you can access the central locking controller. Just make a note of the original code before changing it if you try and reverse it if it doesnt work.
