Product Description

The OEM repair seal kit 30783288 contains the sealing plate, O‑rings, special valve seal and mounting screws required to reseal the Haldex control unit housing on 2nd and 3rd generation systems. Using original BorgWarner seals helps ensure correct fit and long-term sealing performance during service operations. 

Why Replace These Seals

  • Prevents hydraulic fluid leaks from the mechatronics housing
  • Restores correct pressure sealing for valves and pumps
  • Reduces risk of contamination entering the hydraulic system
  • Helps avoid repeated failures after mechatronics or pump repair
Service Recommendation Replace seals when removing the mechatronics unit or during Haldex pump service. Use correct torque on screws and verify sealing after installation. If the mechatronics housing shows corrosion or mechanical damage, replace the housing components as required.

Vehicle Compatibility

This seal kit is commonly used across multiple brands that employed Haldex 2nd and 3rd generation couplings, including Volvo, Land Rover, Ford and many Volkswagen Group models — always verify generation and OEM references before ordering. 

Typical Applications (examples)

  • Volvo S40 / V50 / S60 / V70 / S80 / XC70 / XC90 (certain model years)
  • Land Rover Freelander 2 / other LR models using Haldex 2/3
  • Ford Kuga / Ford models with Haldex AWD
  • Audi A3, TT and other VAG models with Haldex gen2/3
  • VW Golf V, Passat B6, Touran and other VW Group AWD models
VIN Verification Recommended Haldex applications can vary by production date and engine/gearbox configuration. Send us your VIN for a definitive fitment check if needed.

The kit typically includes:

  • Main control unit gasket/sealing plate
  • Several O‑rings and valve seals for the pre‑charge pump and solenoids

  • Assorted screws / mounting hardware required for reassembly
Note Exact kit contents may vary slightly by supplier batch; the provided kit is an OEM BorgWarner replacement intended to match factory specifications. If you require a parts list image or packing list, request it before purchase.

Great selection of parts. Reasonable pricing. Fast delivery and super service/support. My new Haldex ECU worked like a charm, once the car had recognised it (took a couple of restarts of the car and fault code clearing with OBDeleven). Highly recommend!
