Common Symptoms and Fault Codes
A defective N373 valve or sealing problem can commonly cause the following issues:
-
02248 N373 valve fault / AWD disengagement
-
01324 Haldex coupling: no signal from control module
-
00003 AWD control module no communication
-
C1112 Haldex clutch pressure sensor signal implausible
-

-
P1889 Oil pressure pump performance fault

Diagnostic Tip If N373-related faults keep returning, replacing both the valve and the seal kit can be a better service solution than replacing only one component.

Why N373 Valves and Seals Fail
1. Valve Wear or Internal Sticking
The N373 solenoid valve can wear internally over time, causing unstable clutch pressure control and repeated AWD fault codes.
2. Oil Contamination
Dirty or degraded Haldex oil can affect valve operation and contribute to poor pressure control and system faults.
3. Seal Deterioration
Aged or damaged sealing parts can lead to leakage, contamination and reduced system reliability during operation.
4. Incorrect Previous Repairs
Improper assembly, reused seals or incorrect screw torque can create repeat faults after servicing.
