Many European all-wheel drive (AWD) vehicles are fitted with a Haldex AWD electronic coupling. These are common in VW, Audi, Volvo, Range Rover, Porsche, Ford and Skoda vehicles from 1998 onwards. ALLTRANZ has in stock Genuine AWD coupling service items including filters and pumps for Gen 4 onwards (2007+) and oil to suit all generations. Gen 1-3 items are available to order. The recommended service interval on Haldex units is 30000kms.
The coupling is essentially an electronically controlled hydraulic pump and a clutch to provide partial or complete drive to the rear wheels for all-wheel drive mode in normal east-west front-wheel drive vehicles. It is important that the coupling is regularly serviced with a specific grade oil and the filter changed where fitted. All the Gen IV versions of the Haldex coupling have filters fitted. If these are not serviced, then the filter can become blocked and eventually cause the pump to fail. ALLTRANZ hold service information on how to service these couplings.
