Haldex AWD Booster Pump Seal Kit — Generation 4 | OEM 0AY598305
Restore Correct AWD Oil Pressure in Your Haldex Gen 4 Booster Pump — Complete Seal Kit.
The Haldex Gen 4 AWD system uses a booster pump to pre-charge coupling oil pressure. When the pump seals wear, oil pressure drops before engagement — causing delayed or inconsistent AWD activation. This seal kit replaces all pump seals, restoring correct booster pump operation.
