VAG Group. Which generation of the Haldex controller is in my car?
Haldex control units vary depending on the system generation and the vehicle model (Volkswagen, Audi, Skoda, Seat, Volvo, Ford, Land Rover, and others). On this page, you will find instructions on how to identify the generation, a list of vehicles, and the corresponding control unit part numbers, which will help you determine compatibility and repair options.
What is the Haldex system?
The Haldex system is an electronically controlled all-wheel-drive (AWD) system used in vehicles from the VAG Group, such as Audi, Volkswagen, Seat, and Skoda. The Haldex clutch is designed to engage the rear axle when traction is lost or when there is an increased need for traction. Depending on the generation, the system uses different controllers, pumps, and design solutions, which may vary in terms of compatibility and diagnostic methods. Correctly identifying the generation and controller number allows for determining the feasibility of repair, remanufacturing, and selecting the appropriate parts.
