with SKU codes.
Since you are most likely still under warranty, I would just go to the dealership and have them do it.

It might work with our newer cars:
You will need two keys and both remotes to (re)program your remotes. Follow the directions below. Note: the 1996 model year remotes are different and probably will not work the manner below. I do not know the situation with later model years.
Take one key and put it in the ignition and turn the ignition ON.
Close and lock the driver's door with the second key (while the ignition remains on).
Take the first remote and press the "UNLOCK" button ONCE only - alarm will 'beep' but door will remain locked.
With the key, unlock and lock the door again.
Test the remote by pressing the "UNLOCK" button again - door should unlock.
Open the door and turn ignition off and back on again using the first key.
Continue the procedure for the second remote - close & lock the door with the second key (leaving the ignition on).
Take the second remote and press the "UNLOCK" button TWICE - alarm will 'beep' each time button is pressed but door will remain locked.
With the key, unlock and lock the door again.
Test the remote by pressing the "UNLOCK" button again - door should unlock.
Remove both keys, close the door and perform a final retest by locking and unlocking the car with both remotes.

Unofficial method:
I did this for a fellow B6 owner and it worked if the ECU seems to have lost the coding but if you're adding a key this probably won't work:
Try putting the key in the ignition with it in accessory mode and hold down the unlock or lock
button for 10-15 seconds at a time.
Official Remote transmitter coding procedure
Switch ignition on (using separate key).
Check how many transmitters have already been coded in measuring value block 003 Read Measuring Value Block. Refer to "Measuring Value Blocks (Function 08)/Evaluating Measured Value Blocks" See: Body and Frame\Locks\Power Locks\Testing and Inspection\Measuring Value Blocks (Function 08)
Indicated on display
Read Measuring Value Block 3 ->
0 0001 0 0000
Display field 2 indicates how many remote transmitters have been coded and in which memory positions (in the example given, 1 transmitter in position 1).
Lock vehicle from outside using key to be coded via driver-side door lock.
Press "unlock" button within 5 seconds often enough to reach next memory position (in example given, twice). Every press of the button is confirmed by the emergency flashers and the anti-theft system horn.
Wait 5 seconds.
Now press "unlock" button one more time (vehicle unlocks).
Switch ignition off and remove ignition key.
Check function of new transmitter.
Check display field 2 in measuring value block 003. It should now display another "1" (in example given: 1100).
NOTE: Be sure that new transmitters are always coded into free memory positions. If occupied positions (distinguishable by a "1") are used, the transmitter previously coded to this position will no longer work.
Existing remote transmitter recoding procedure
This procedure must be performed after changing the batteries in keys with remote control function, or if the scan tool displays DTCs of 00955 to 00958
Press any button on transmitter.
If vehicle does not respond by locking or unlocking :
Lock and unlock vehicle within 30 seconds using driver-side lock.
Now check function of recoded remote transmitter.
Clearing memory positions
NOTE: It is possible to clear all memory positions, e.g. if a customer loses a remote transmitter. Proceed as follows:
Switch ignition on using key.
Then mechanically lock central locking from outside vehicle using key.
Activate remote transmitter "unlock" button on key five times at one second intervals.A short horn signal will sound each time.
Then, after 6 seconds , press remote transmitter "unlock" button to confirm this clearing procedure one more time. Central locking should no longer unlock itself via remote transmitter.
Switch ignition off.
Up to four transmitters can now be coded again

Dealer won't give you the SKU code, so you will need to probably get car towed to dealer.
