Product Description
This original used N373 valve is designed for 4th generation Haldex AWD systems. It is a precision oil control valve used to regulate clutch operating behaviour inside the Haldex coupling and plays an important role in correct all-wheel-drive function. [web:179][web:182]
What This Valve Does
- Controls oil flow between internal Haldex channels
- Regulates clutch operating angle and coupling behaviour
- Supports correct AWD engagement and disengagement
- Helps maintain proper hydraulic control inside the Haldex unit
- Serves as a replacement for defective original N373 valves
Installation Information
Because the N373 valve is a precision hydraulic control component, correct diagnosis should be confirmed before replacement. Careful handling during installation is important, as damage or contamination can affect valve performance. [web:182]

Common Fault Codes & Symptoms
A defective N373 valve can affect oil control inside the Haldex unit and may contribute to AWD malfunction, abnormal clutch behaviour or warning messages. Publicly referenced fault information connects this valve with the diagnostic code 02248 and with issues related to clutch control and oil regulation. [web:179][web:182][web:188]
-
02248 Valve for Controlling Clutch Operating Angle (N373) – intermittent or defective
-
P0961 / P0962 Control solenoid / algorithm-related fault associated with valve operation
-
Restricted oil control Incorrect oil routing inside the Haldex coupling
-
Clutch control fault Improper engagement or release behaviour of the clutch pack
- Rear axle engagement problems
- AWD not working correctly or engaging late
- Unwanted clutch engagement behaviour
- Warning messages related to Haldex or traction system
Diagnostic Tip
Similar symptoms can also be caused by ECU faults, pump problems, wiring issues or contamination inside the Haldex unit, so the N373 valve should be diagnosed as part of the full AWD system rather than by fault code alone. [web:181][web:182][web:188]
Installation & Service Notes
Recommended Steps
- Verify the OEM number on the original N373 valve
- Confirm that the vehicle uses a 4th generation Haldex system
- Inspect the Haldex unit for contamination or related hydraulic faults
- Install the replacement valve carefully and keep the component clean
- Check electrical continuity and system operation after installation
- Confirm AWD function with diagnostic equipment and road test if required
Important Service Note
The N373 valve is a sensitive precision component. Rough handling, dirt contamination or incorrect diagnosis can lead to repeat AWD problems even after replacement. [web:182]
Why the N373 Valve Matters
1. Oil Control
The valve regulates internal oil flow paths inside the Haldex coupling.
2. Clutch Operation
It supports correct clutch operating angle behaviour and controlled AWD response.
3. AWD Performance
Correct valve operation helps the Haldex system engage and release the rear axle properly.
4. System Reliability
A properly functioning N373 valve helps reduce oil control faults and supports stable Haldex operation.
