Product Description
This new original BorgWarner Haldex pre-charge pump with part number 0CQ598549 is designed for 5th 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 5 Haldex pump, we strongly recommend using fresh Haldex oil G060175A2 and carrying out AWD basic settings after installation.

Common Fault Codes & Symptoms
A faulty Gen 5 Haldex pump can cause AWD engagement problems, pump pressure faults, and traction issues. Common pump-related symptoms and diagnostic codes include:
-
C111204 Haldex clutch pump faulty
-
02248 Valve / pump-related Haldex fault
-
16671 / C1112 04 Pump for Haldex clutch internal system fault
-
16668 / C1112 07 Pump for Haldex clutch mechanical failure intermittent
-
AWD does not work Rear wheels do not engage correctly
-
ESP / ABS warning Warning lights may be illuminated together with AWD fault
- Rear-wheel drive not engaging when traction is needed
- Front wheels slipping excessively before rear axle activation
- Reduced stability in slippery conditions
- Loss of rear-wheel traction caused by weak or failed pump pressure
Diagnostic Tip
If the AWD system does not work and the all-wheel-drive control module stores C111204, one common cause is an internal leak or failure inside the hydraulic pump. On VAG Gen 5 systems, pump replacement, fresh Haldex oil, and AWD basic settings are standard service steps.
Installation & Service Notes
Recommended Steps
- Verify the exact OEM number on the original Haldex pump
- Replace the hydraulic pump according to the factory repair procedure
- Use fresh high performance oil for Haldex coupling G060175A2
- Make sure the Haldex coupling and final drive oils are not confused
- Perform AWD basic settings after pump replacement
- Clear stored AWD fault codes after installation
Important Service Note
The final drive and the Haldex coupling use separate oil circuits. Use the correct Haldex oil when replacing the pump and complete the AWD basic settings after service.
Why Haldex Pumps Fail
1. Internal Hydraulic Leak
Gen 5 pumps can fail 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. Pressure Build-Up Problems
If the pump cannot build proper hydraulic pressure, the AWD clutch pack will not engage correctly and traction performance will drop.
4. Ignored AWD Fault Codes
Continuing to drive with AWD fault codes or warning lights can lead to worsening AWD performance and additional system wear.
