You would find it in models such as the VW Golf (MK5), Passat (B6), Touran, and Caddy, as well as in vehicles from other brands within the group like SEAT and Skoda. Its integrated security system is designed to prevent theft by requiring a unique code whenever it is disconnected from the car's primary power source.
