Topping up oil in Haldex coupling Test precondition l  Vehicle level. –  Top up with high-performance Haldex coupling oil. High-performance oil for Haldex coupling is available as a part → Electronic parts catalogue „ETKA“. –  Raise vehicle. Vehicles with cross member:

–  Cover cross member with cloth. If oil should land on the cross member or in the perforations in the cross member, carefully remove all oil. –  To top up oil, use Filling device for Haldex coupling 2 -VAS 6291-. –  Place drip tray -VAS 6208- under final drive.

–  Remove oil filler plug -arrow-. (For sake of clarity, shown with final drive removed.)

–  Screw in adapter -A- to stop. –  Engage elbow -B- in adapter -A-. –  Route hose above drive shaft. l  Hose must not sag. It must exit at rear of vehicle above left rear wheel. –  Lower vehicle.

–  Ensure that valve -arrow- is closed. –  Screw oil reservoir -A- onto filler device for Haldex coupling II -VAS 6291-. –  Now open valve -arrow- and hold oil reservoir as shown in figure. The Haldex coupling will now be filled. –  After a few minutes, raise vehicle.   Note t  If Haldex coupling has been properly filled, oil will have run out at adapter -A-.

t  If no oil has run out, lower vehicle and perform filling procedure again. –  Raise vehicle. –  If oil has run out, place oil reservoir below Haldex coupling (e.g. on a tool cart). Excess oil will now flow back into oil reservoir. –  When no more oil flows back, remove filler device -VAS 6291-.

–  Screw in plug -arrow- and tighten. Torque setting → Chapter –  Then check oil level in Haldex coupling → Chapter.
