Don't miss

  • Ensure that valve (arrow) is closed.
  • If Haldex coupling has been properly filled, oil will have run out at adapter (A).If no oil has run out, lower vehicle and perform filling procedure again.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

  1. Remove oil filler plug (arrow). (For sake of clarity, shown with final drive removed.)
  2. Screw in adapter (A) to stop.
  3. Engage elbow (B) in adapter (A).
  4. Route hose above drive shaft.
  5. Lower vehicle.
  6. Ensure that valve (arrow) is closed.
  7. Screw oil reservoir (A) onto filler device for Haldex coupling IIVAS 6291.
  8. Now open valve (arrow) and hold oil reservoir as shown in figure.
  9. After a few minutes, raise vehicle. [Note: If Haldex coupling has been properly filled, oil will have run out at adapter (A).If no oil has run out, lower vehicle and perform filling procedure again.]
  10. Raise vehicle.
  11. If oil has run out, place oil reservoir below Haldex coupling (e.g. on a tool cart).
  12. When no more oil flows back, remove filler deviceVAS 6291.
  13. Screw in plug (arrow) and tighten. Torque setting
  14. Then check oil level in Haldex coupling .

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
