Audi A4 (B9) 1.4 TFSI Lockset | CVN Engine Code | 2016–2020 | ECU, Key & BCM Kit

Description

Get your luxury sedan back on the road with this precision-matched Audi A4 B9 1.4 TFSI Lockset. Specifically compiled for the CVN engine code found in the 2016–2020 B9 platform, this complete electronic security kit is the definitive solution for vehicles suffering from immobilizer failures, unrecoverable key loss, or “Component Protection” faults that prevent the vehicle from starting.

In the Audi B9 architecture, the security system is highly integrated across multiple modules. A standard lockset for this generation includes the Engine Control Unit (ECU), the Body Control Module (BCM), and the Smart Key. These units are digitally “married” to one another via Audi’s advanced security protocols. If synchronization is lost or a module is damaged by a voltage surge, the car will fail to recognize the key or crank the engine. This matched set provides a synchronized solution, significantly reducing the complexity and cost associated with programming individual new modules at a dealership.

Sourced from low-mileage CVN 1.4 TFSI units, this lockset ensures that your fuel maps and turbocharged performance parameters remain factory-accurate. Each component is rigorously tested for communication stability and pin integrity. Trust TP German Auto Spares for verified, high-quality Audi electronic components that restore the reliability and high-tech security of your A4.
