Term to be used in place of “Haldex” with immediate effect. Legal implications make this step necessary. The term may nevertheless appear in older documents but need not be replaced. |
The Haldex System is used by Volkswagen Audi Group (VAG) on their all-wheel drive (AWD) vehicles, the system comprises of an oil pressure activated clutch coupling which can switch the vehicle from Front-Wheel Drive (FWD) to all-wheel drive in an instant.
Some of the newer high performance VAG FWD vehicles are also fitted with a system similar to the Haldex Coupling featured on the AWD VAG vehicles. (More on VORDERACHSQUERSPERRE – VAQ system HERE)
The Haldex System has an electronic controller that messages the differential to send power to an individual wheel allowing better traction control, the vehicle’s ability to switch between the two drive systems provides the benefit and economy of a 2WD but also the performance and handling of an all-wheel drive when you need to engage all the wheels.
The benefits include:
- Improved traction
- Refined driving behaviour
- Optimum powertrain strategy for cornering, overrun mode or towing
- Intelligent balance of force between the front and rear axle
- Improved Stability for both on-road and off-road conditions
As the Haldex system works on an oiled clutch, it will require servicing at regular intervals to maintain performance and efficiency. The manufacturers recommendation for servicing is oil change every 20,000 miles & filter change every 40,000 miles however, in our opinion, this should be done on an annual interim service depending on your driving style and which generation Haldex System is fitted to your vehicle.

Why should you service your Haldex System regulary?
Your AWD Haldex coupling is a complicated piece of kit, the multi-plate clutches engaging when your vehicles AWD kicks in creates friction between the surfaces of the coupling. Due to friction within the Haldex Coupling it will inevitably, over time will cause a build-up of small particles which contaminate the fluid and block the filters and strainers.

The Haldex Coupling needs to remain submerged in clean Haldex High Performance Oil, this wet clutch system is what engages the rear final drive on your vehicle. If the Haldex Oil becomes contaminated and your filter or strainer become clogged, this can directly result in the multi-plate clutch & pump overheating due to starvation of the fluid it requires to operate. This could potentially damage other components of the Haldex assembly.

The Haldex system can suffer with a build-up of condensation due to inactivity, if the system is rarely used this build-up stops the Haldex Oil activating as it should therefore resulting in damage to the friction plates in the clutch.
