Your car has a 'rolling code' type immob capsule in the key part of the remote.
You can not clone this type of immob capsule/chip.
It needs to be taken to the audi dealer, sometimes even if you have vagcom & your SKC.
If you are replacing a worn key you can swap over the capsule to your new remote.
The Audi dealer should have been able to make the new key work, no prob's?
