Product Description


If your AWD P3, P5, or P6 Volvo has unexpectedly left you stranded in slippery conditions, it's possible your car's AWD needs service.

Non-hybrid modern Volvos (like T4, T5, and T6 trims of the XC40, S60, V60, S90, V90, and XCs and CCs) use a system called Haldex to engage the rear wheels when the front wheels start to slip.

This Haldex system relies on a multi-plate clutch in the rear of the car, also called the Active On-Demand Coupling (AOC). When the system detects front wheel spin, valves open and allow pressurized oil to clamp the clutch down, hooking up the rear wheels and getting you moving again.

The system relies on oil pressure as high as 80 bar (1100psi!) to cycle the hydraulic clutch, and just like any system that pumps oil around, regular fluid changes are recommended. For Haldex, we suggest changing the fluid every 50,000 miles

A clogged (and failed!) Haldex pump

If fluid changes are neglected, the Haldex pump filter screen can start to get clogged and the pump has to work harder and harder until it eventually burns out: you'll suddenly get lots of front wheel spin, and when scanned the car will have pump error codes from the DEM, such as DEM-0006.

This kit contains new fluid, a bottle of Haldex oil, new fasteners, covers, and o-rings, and a new pump made by the Original Equipment supplier for Volvo. If you've got pump-related DEM codes or if you've hooked 12v up to the pump and heard nothing but silence, this is the kit for you!
