CAS Data Read

Reading the Car Access System's immobiliser data, which is what a new key is generated from. On second-generation MINIs this is normally done through the OBD port; encrypted CAS3+ versions, all-keys-lost jobs and replacement modules can force a direct read of the CAS EEPROM and processor on the bench.
