Product Description

This original used N373 valve is designed for 2nd and 3rd generation Haldex AWD systems. It is an electro-hydraulic control valve used inside the Haldex clutch assembly to regulate oil flow and support proper clutch control during all-wheel-drive operation. [web:191][web:193]

What This Valve Does

  • Controls hydraulic oil flow inside the Haldex coupling
  • Supports clutch engagement behaviour in the AWD system
  • Helps maintain correct rear axle activation when required
  • Contributes to stable operation of the Haldex control system
  • Serves as a replacement for defective original N373 valves
Installation Information Because this valve works inside the hydraulic control system of the Haldex unit, diagnosis should be confirmed before replacement. Contamination, pump problems, ECU faults or pressure-related issues can create similar symptoms.

Vehicle Compatibility

This valve is suitable for selected vehicles equipped with 2nd or 3rd generation Haldex coupling. Publicly available references confirm the part for Gen 2 / Gen 3 Haldex systems, but exact fitment should always be verified according to the original valve and AWD unit version. [web:191][web:193]

Suitable for Selected AWD Applications

  • Selected Volvo AWD models with Haldex Gen 2 / Gen 3
  • Selected Land Rover AWD models with Haldex Gen 2 / Gen 3
  • Selected Saab AWD models with Haldex Gen 2 / Gen 3
  • Selected Opel AWD models with Haldex Gen 2 / Gen 3
  • Other vehicles equipped with original Haldex 2nd or 3rd generation coupling using N373 valve
Not Sure About Compatibility? If you are unsure whether this valve fits your vehicle, send us your VIN number or the OEM number from your original Haldex component. We will help confirm compatibility before you order.

Common Fault Codes & Symptoms

A defective N373 valve can contribute to poor AWD engagement, rear axle activation problems or Haldex malfunction symptoms. Similar issues may also be caused by pump faults, ECU defects, contaminated oil or internal hydraulic problems, so professional diagnosis is recommended before replacement. [web:193]

  • AWD malfunction Rear axle does not engage correctly
  • Oil control fault Improper hydraulic regulation inside the Haldex unit
  • Clutch control issue Unstable or delayed clutch operation
  • Rear axle inactivity Weak or missing four-wheel-drive support
  • Traction loss at the rear axle under load
  • Intermittent AWD behaviour
  • Juddering or unusual drivetrain response during acceleration or cornering
  • Repeated Haldex-related complaints after service
Diagnostic Tip When diagnosing Haldex faults, the N373 valve should always be checked together with the pump, pressure condition, ECU and oil contamination level. Replacing the valve alone may not solve the issue if another part of the system is faulty.

Installation & Service Notes

Recommended Steps

  • Verify that the vehicle uses 2nd or 3rd generation Haldex
  • Check the OEM number or physical type of the original N373 valve
  • Inspect the Haldex unit for oil contamination or related hydraulic issues
  • Install the replacement valve carefully in a clean working environment
  • Check AWD operation after installation
  • Perform diagnostic verification if faults were previously stored
Important Service Note The N373 valve is a sensitive hydraulic control component. Improper handling, dirt contamination or incorrect diagnosis can lead to repeat AWD problems after installation.

Why the N373 Valve Matters

1. Oil Regulation

The valve helps regulate hydraulic oil control inside the Haldex clutch system.

2. Clutch Operation

It supports proper clutch engagement behaviour required for AWD activation.

3. Rear Axle Response

Correct valve operation helps the Haldex system transfer torque to the rear axle when needed.

4. System Stability

A properly functioning valve contributes to smoother and more reliable AWD operation.
