Product Description
This original 0AY598301 repair seal kit is designed for 4th generation Haldex control units. It is used when the AWD ECU housing has been opened for repair, testing or internal service and needs to be resealed correctly before reinstallation. [web:194][web:197][web:200]
What This Seal Kit Does
- Provides the sealing components needed to reseal the Haldex control unit housing
- Helps protect the ECU against moisture, dirt and environmental contamination

Common Service Situations
This repair seal kit is typically used when the Haldex control unit has already been opened for internal repair, testing or inspection. It is not a fault-fixing electronic component by itself, but an essential sealing part used during professional ECU service work. [web:196][web:197][web:198]
-
ECU housing opened Control unit was disassembled for repair or inspection
-
Old seal damaged Original gasket or sealing strip no longer suitable for reuse
-
Moisture protection required ECU housing needs proper resealing before installation
-
Service reassembly Replacement screws and new sealing parts required after repair
- Visible damage to the old gasket or seal strip
- Control unit cover removed during diagnostic or repair work
- Preventive resealing during refurbishment of Haldex ECU
Important Note This kit is intended to reseal the control unit housing. It does not repair internal electronic damage, pump faults or hydraulic problems inside the Haldex system.
Installation & Service Notes
Recommended Steps
- Verify that the vehicle uses a 4th generation Haldex control unit
- Remove all old sealing material carefully from the housing surfaces
- Inspect the control unit cover and housing for damage before reassembly
- Install the new sealing strip and gasket correctly
- Use the supplied screws during reassembly where applicable
- Make sure the control unit housing is closed evenly and securely
Important Service Note Correct sealing of the Haldex ECU housing is essential. Poor reassembly, damaged sealing surfaces or incorrect tightening can reduce protection against moisture and dirt after repair. [web:196][web:198]
Why Proper ECU Sealing Matters
1. Moisture Protection
A correct seal helps protect sensitive electronics inside the Haldex control unit from water ingress and condensation.
2. Dirt Protection
Proper sealing reduces the risk of contamination entering the ECU housing after repair.
3. Reliable Reassembly
The correct kit supports cleaner and safer reassembly after testing or refurbishment of the control unit.
4. Long-Term Service Quality
Using the proper seal kit can help reduce repeat problems caused by poor housing closure after ECU work.
