whereabouts you located? might be worth putting a shout out for someone local to you with VAG COM who can do a little digging.
does the central locking still work via the key in the door?
try the following:
You can do this yourself, there is a procedure for doing it. One using VAG COM, and the other using the ignition barrel of the car.
VAG COM :
1. All doors must be shut (can have drivers door open, just flick the switch in the lock so it thinks it shut!)
2. Key in ignition, turned on, not running (usual vag com stuff)
3. Start VAG Com
4. go into 46. Cent. Conv
5. 10 - Adaptation, chanel 1 change key number to 2 (if you have 2 keys) save > done go back
6. go back into cent. conv and select 08. meas. blocks
7. meas block 13 - with key in the ignition, press the button, you will see it say ok (x3) and key number 1.
8. press the buttons on your other key with key 1 still in the ignition & hopefully you will see it say ok (x3) and key number 2.
9. unplug vag com, get out the car with the keys and test!!
Without VAGCOM
1. Place your first key into the ignition and turn to the second notch (do not start the car)
2. Now close the door and place your second key into the handle lock
3. Turn the key to the lock position and let it spring back to the central position.
4. Hold down the Lock button on your new remote, you may hear a bleep from the car
5. Now unlock the car using the key in the barrel and remove, then take your first key out of the ignition
6. Close the door
7. Your remote should now be coded
you will need a second remote though
