If it is for an A4 2002 and up you need to get it coded by the dealer for Immobilizer III if I am not mistaken. It is the same if you change ECUs.
Only the Audi factory will release the code to the mechanic after he sends your info to them.
I assume you are talking about the cluster unit.
So they would have to install it and then code it otherwise you are not able to start the car.
