I've been bench testing a few instrument clusters from the Audi A8 4E. One of the clusters has CP active and I've recoded the cluster with random codes just to see what would happen... Now it's locked down and I have to wait before I can try again. Anybody know the time limit in between CP recoding attempts? It's been powered up for 10 hours and still locked. The equipment is surplus and isn't precious as it's more of a self learning exercise.

Some interesting observations after I read the EEPROM from the cluster, I can see the VIN and authorisation module serial number of the car it was originally installed in.
