Product Description
This new aftermarket Haldex pump with part number 31367750 is designed for 5th generation Haldex / AOC AWD systems used in selected Volvo and Land Rover vehicles.

- Restores rear-wheel engagement when the front wheels begin to slip
- Supports proper operation of the DEM / AWD control system
- Helps eliminate AWD failure symptoms caused by a worn or blocked pump
Service Recommendation
When replacing the Gen 5 Haldex pump, we strongly recommend inspecting and cleaning the pump strainer, filling with fresh Haldex oil, and performing the correct calibration procedure after service.

Common Fault Codes & Symptoms
A faulty Gen 5 Haldex pump can cause rear AWD loss, AWD disabled messages, or pressure-related DEM faults. Common symptoms and diagnostic codes include:
-
P1889-71 Oil pressure pump performance fault / possible internal leak or pump damage
-
P1889-18 Air entered the AWD clutch package during filling / bleeding issue
-
P1889-14 Oil pressure pump performance – circuit short to ground or open circuit
-
DEM-0006 Often pump-related AWD pressure / pump fault
-
DEM-0007 Often pressure sensor related, but may also be caused by pump issues
- Rear-wheel slippage / front wheels spinning without rear engagement
- AWD failure message on dashboard
- ESP / traction warning lights
- AWD system disabled or intermittent AWD operation
Diagnostic Tip
If the pump strainer is clogged, the pump must work harder and may eventually burn out. On Volvo systems, pump issues are commonly logged in the DEM / AWD module and should be diagnosed before replacing other components.
Installation & Service Notes
Recommended Steps
- Verify the exact OEM number on the original Haldex pump
- Remove the pump and inspect the strainer / gauze screen
- Clean the strainer with a lint-free cloth only
- Do not use cleaning liquids inside the pump sump or coupling housing
- Fill the coupling with fresh Haldex oil to the correct level
- Perform the correct calibration procedure after service
- Clear AWD / DEM fault codes after installation
Important Service Note
A clogged strainer is one of the most common causes of pump failure on Gen 5 systems. Replacing the pump without checking the strainer and renewing the oil can shorten the life of the new unit.
Why Haldex Pumps Fail
1. Clogged Strainer / Gauze Screen
When the pump screen becomes blocked by contamination, the pump has to work harder to build pressure and can eventually burn out.
2. Old or Contaminated Oil
Neglected Haldex oil increases internal resistance and accelerates wear of the pump motor and pressure circuit.
3. Internal Pump Wear
Worn internal components, leaks, or electrical faults can cause pressure loss and AWD performance problems.
4. Incorrect Filling or Missing Calibration
Air in the coupling or missing calibration after service can trigger Gen 5 pressure faults and unstable AWD operation.
