Product Description
This new original BorgWarner hydraulic pump with part number 0AV598549A is designed for 2nd generation Haldex AWD systems used across a wide range of VAG 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 2 Haldex pump, we strongly recommend using fresh Haldex oil G055175A2 and replacing the filter 02D598574 at the same time for reliable AWD operation.

Common Fault Codes & Symptoms
A faulty Gen 2 Haldex pump can cause AWD engagement problems, loss of hydraulic pressure and driveline issues. Common pump-related symptoms and diagnostic signs include:
-
Loss of rear-wheel drive Rear axle does not engage correctly
-
Communication errors Faults stored in the AWD module
-
Dashboard warning lights Warning lamps may be illuminated together with AWD fault
-
Weak AWD operation Reduced torque transfer to the rear axle
- Front wheels slipping excessively before rear axle activation
- Reduced traction and stability in slippery conditions
- Driveline issues caused by low hydraulic pressure in the Haldex coupling
- Improper AWD response due to worn pump, contaminated oil or blocked filter
Diagnostic Tip
If the AWD system does not engage properly and the vehicle shows rear-wheel-drive loss or AWD module communication faults, one common cause is reduced hydraulic pressure from a worn or failed Haldex pump. On Gen 2 systems, pump replacement together with fresh oil and filter service is a standard repair step.
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
- Use fresh original 2nd generation Haldex oil G055175A2
- Replace the filter 02D598574 during pump replacement
- Check the AWD system for stored faults after installation
- Verify proper rear axle engagement after service
Important Service Note
A worn filter or contaminated oil can overload the new pump and shorten its service life. For reliable repair, replace the oil and filter together with the pump.
Why Haldex Pumps Fail
1. Internal Pump Wear
Gen 2 pumps can wear internally and lose the ability to create the oil pressure needed for clutch engagement.
2. Contaminated or Old Haldex Oil
Old oil increases wear inside the pump and reduces the performance of the AWD coupling.
3. Blocked Filter
A restricted filter reduces oil flow and can overload the pump, causing weak AWD operation or pump failure.
4. Ignored AWD Fault Symptoms
Continuing to drive with AWD warning symptoms can lead to worsening traction performance and additional drivetrain wear.
