Haldex is the standard intelligent all-wheel-drive system found on a variety of Volkswagen Automotive Group models but is most associated with current-generation cars using VW’s MQB platform.
The current, fifth-generation Haldex system is designed to be the least complex yet, featuring the fewest number of components to make maintenance as simple as possible.
A simple Haldex system consists of a hydraulic pump, a clutch, and an electronic valve.
This diagram from Haldex Repairs shows it pretty simply:
The early Haldex units purely reacted to the front wheels slipping – the difference in speeds between front and rear activated a pump to engage the rear-drive.
Later generations were able to anticipate when more power needed redirecting to the rears, whilst the latest 5th generation of Haldex unit continually sends 10-15% of power to the rear wheels, plus more when is needed.

Haldex all-wheel, Quattro, and 4motion drives are commonly found in AWD vehicles from,
- Ford
- Volkswagen
- Audi
- Seat
- Skoda
- Vauxhall
- Land Rover
- Volvo, and many more.
The units were widely adopted by manufacturers because they are less bulky than Transfer Boxes and consume far less fuel than traditional four-wheel-drive systems when driving normally along roads and motorways because the rear shafts aren’t spinning.
No matter which type of Haldex unit your vehicle has or where it is located, it will still need regular oil and filter changes, just like your engine does.
Also, you may need to change it more frequently, from every 20,000 miles.
In addition, the pump is prone to failure on high mileage vehicles so it’s reassuring to get it looked at by an expert mechanic during service.
A Haldex unit is a complicated piece of engineering with very fine tolerances so regular maintenance is vital to keep it in working order.
If the Haldex fluid is dirty it can damage components and affect performance.
Dirty fluid can also cause the coupling to overheat and the clutches to burn out.
In severe cases, it can also burn out the Haldex Pump leading to loss of rear-drive and failure of the whole unit.
Another point to note about Haldex systems is that the fluid inside them is not a lubricating oil like you’d find in your engine or transmission.
The fluid is a very special product that actually promotes friction between the clutch plates.
Because of this, over time particles will start to build up in the oil, which is why a regular service of both the oil and filter is vital.
In modern units with an oil strainer instead of a filter, this will still need cleaning during the service.
