Product Description
If your AWD Volvo has unexpectedly left you stranded in slippery conditions, it's possible your car's AWD needs service.
Modern Volvos use a system called Haldex to engage the rear wheels when the front wheels start to slip.
A cutaway diagram of the Active On-Demand Coupling
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 and filter changes are recommended. For Haldex, we suggest changing the fluid and filter every 50,000 miles
A clogged (and failed!) Haldex pump
If fluid changes are neglected, the filter can start to get clogged and the Haldex 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.

Available to Order means the item may not be in our warehouse but is readily available from one or more supplier warehouses. After you order it, we will get it for you ASAP.
Products from major brand names are almost always in stock in the manufacturer’s domestic warehouse. These suppliers have good fill rates, but even if they are out of stock, we may be able to source it from a variety of alternative wholesale sources.
We are at the most a week away from all these warehouses, usually much less. Does that mean we will always have your product available within that window? Honestly, we can't promise that but we’ll do everything we can to get your parts to you in a timely manner.
