Audi A3 (8P) 1.6 TDI Lockset | CAY Engine Code | ECU, Key & Cluster Module

Description

Resolve complex immobilizer faults and ignition failures with this complete, matched Audi A3 1.6 TDI Lockset. Specifically sourced and configured for models equipped with the 1.6 TDI CAY engine (typically found in the 2010–2013 Audi A3 8P generation), this kit is the definitive solution for vehicles suffering from corrupted ECU data, lost keys, or a damaged immobilizer system.

In modern Audi vehicles, the engine security framework relies on a highly synchronized data link between multiple control modules. If the data mismatch occurs, the vehicle will trigger an active immobilizer fault, preventing the car from starting. This complete lockset eliminates the need for expensive individual module coding or dealership programming by providing a pre-coded, plug-and-play solution. Simply install the components together to restore immediate communication and fire up your fuel-efficient 1.6 TDI engine.

Every component in this lockset has been meticulously tested and verified as a matching group. The set includes the primary Engine Control Unit (ECU) programmed for the CAY engine code, the instrument cluster (which houses the immobilizer control chip), the ignition barrel mechanism, and the corresponding transponder key. Trust TP German Auto Spares for verified, reliable electrical and security components that get your Audi A3 back on the road safely.
