Product Description
This new aftermarket Haldex pre-charge pump with OEM references 31256757 / LR008958 / 9V4N-4C019-AA is designed for 4th generation Haldex AWD systems used across selected Volvo, Ford and Land Rover vehicles. The pump creates the hydraulic pressure required to activate the AWD clutch pack and engage rear-wheel drive when traction is needed.
What This Pump Does
- Builds hydraulic pressure for Haldex clutch engagement
- Restores rear-wheel drive activation in AWD conditions
- Supports correct operation of the AWD coupling and factory electronics
- Helps eliminate traction loss caused by a weak, blocked, or failed pump
Service Recommendation
When replacing a Gen 4 Haldex pump, we strongly recommend replacing the Haldex oil and filter at the same time. A clogged filter can overload a new pump and shorten its service life.
Vehicle Compatibility

Common Fault Codes & Symptoms
A faulty Gen 4 Haldex pump can cause AWD engagement problems, pump electrical faults and traction issues. Common pump-related symptoms and diagnostic codes include:
-
00448 Haldex clutch pump (V181) lower limit exceeded / intermittent
-
00448 Haldex clutch pump (V181) open circuit
-
DEM-0006 Pump-related AWD fault on some Volvo applications
-
AWD does not work Rear wheels do not engage correctly
-
Traction loss Front wheels slip before rear axle activation
- Jumping or skipping wheel sensation during tight turns
- Binding sensation when doing tight turns
- Reduced stability in slippery conditions
Diagnostic Tip
A healthy Gen 4 Haldex pump typically measures around 5 to 8 ohms. If the pump is out of range, intermittently dead, or only runs after tapping, it is usually defective and should be replaced together with the filter service.
Installation & Service Notes
Recommended Steps
- Verify the exact OEM number on the original Haldex pump
- Replace the hydraulic pump according to the correct repair procedure
- Replace the Haldex filter and oil at the same time
- Check the pump wiring and connector if electrical faults are present
- Clear stored AWD fault codes after installation
- Verify proper AWD operation after service
Important Service Note
On Gen 4 systems, replacing the pump without replacing a clogged filter can quickly damage the new pump. For reliable repair, service the filter and oil together with the pump.
Why Haldex Pumps Fail
1. Internal Wear
Gen 4 pumps can wear internally and lose the ability to create the oil pressure needed for clutch engagement.
2. Clogged Filter
A restricted filter forces the pump to work harder until it overheats or burns out.
3. Contaminated or Old Haldex Oil
Old oil increases wear inside the pump and reduces the performance of the AWD coupling.
4. Ignored AWD Fault Codes
Continuing to drive with AWD fault codes or warning symptoms can lead to worsening traction performance and additional system wear.
