2002 Audi should be RB4 and at least in North America do not require a dealer pre-programmed key, it adds the 7 byte CS to the key the first time it is programmed (must be virgin id48 or id48 audi can chip if not a key already programmed to the car before).
If you can re-enable the immobilizer try with the pincode using vcds or similar tool. Watch out for lock times, could have been the cause in the first place. It should also only have a 4-digit skc (plus leading zero), so keep that in mind. At least in North America I have not seen an RB8 cluster before 2005.5 (not sure if it can be retrofitted but have not seen one from the factory that way)
To check if it’s non or crypto, the case on RB4 cluster has simple solutions with Pin. If you get 5 digit pin you have NONE crypt cluster. Also you can compare Immo block with Crypt one and there will be big difference.I always said , it is not tool that makes perfect job , it is person who using it.
When you read cluster there will never be damage.
Damage comes with writing.
To deal the dash with vvdi2 auto detect , sometimes it works but sometimes it doesn’t . i just find out that its not working most the times. I’ve done many and they have worked but this car didn’t. so i guess like the members here said , get pin code from ECU and adapt it with VCDS
can’t simply get another dump, then make it virgin, then use the pin from ecu + vcds to adapt the dash.
