Connecting a computer system to the On-Board Diagnostic (OBD-II) port.Accessing the lorry’s security pin code.Syncing the rolling codes of the remote to the Central Convenience Module.In more recent designs (Immobilizer V and VI), this process needs a safe live connection to Audi’s servers.Expense Comparison: What to Expect
