Hi Conan,
Just to let you know I have managed to code both sets of keys using the following procedure. Both remotes now work fine except there in no horn toot when locking. Something I can live without.

AUDI A8/S8 (1997-1999)

Procedure

AUDI A8/S8: Programming the Key Fob

Remote Control Programming (1997 ON)

Procedure

1. Switch Ignition ON and leave the key in the ignition.
2. Mechanically lock the vehicle using the Drivers door using a second key.
3. Using the remote control press the Unlock button once, and the horn will sound once.
4. Wait 6 seconds and press the unlock button once to activate the coding
procedure. The remote control will now be programmed.

NOTE : When performing programming on additional remotes the procedure
is the same, except you press the unlock button 2, 3 or 4 times for the
different remote.
For example : If programming 2 remotes press the unlock button twice with
a 1 second interval between each press, repeat for 3 and 4 remotes.

5. Switch Ignition OFF.
6. Remove key from ignition and check for operation.
7. The coding procedure can be repeated up to 4 times for additional remotes.
8. The ignition must be switched OFF between programming each remote
control.

Thanks for your efforts & help at yesterdays Regional meet

Should this be added to a sticky??
