How a Haldex 4WD system works
The Haldex 4WD system used on the transverse-mounted VAG 4WD cars consists of two components: a Haldex Clutch Coupling and the Rear Final Drive Differential. As well as this, some of the performance 2WD models now have a Haldex front differential which works in a similar way.
Haldex coupling. This is a wet multi-plate clutch system operated by a fluid pump (the Haldex Controller) which requires servicing every 20,000 miles in the way of fresh Haldex oil and a new Haldex filter.
Final Drive Differential. The mechanical system that 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.

4WD car? Don't forget the DSG
Many Haldex-equipped cars also run a DSG gearbox — that needs servicing every 40,000 miles too. We service every DSG, ATF and CVT box in the VAG range.
