The Haldex 4wd System used on the Transverse Mounted VAG 4 Wheel Drive Systems consists of two components, A Haldex Clutch Coupling and the Rear Final Drive Differential.
Haldex coupling - This is a wet multi-plate clutch system operated by a fluid pump (Haldex Controller) which requires servicing every 20,000 miles in the way of fresh Haldex Oil and a new Haldex Filter.
Final Drive Differential – This is the mechanical system which provides the drive to the two rear wheels. This uses a lubricating gear oil which according to the owner’s manual is a lifetime fluid. Many of our customers however choose to replace this oil between 50,000 and 75,000 miles as a matter of preventative maintenance.
