Haldex coupling (Golf 4motion): Change

oil

Note

On vehicles with Haldex coupling the drain plugs and sealing

plugs of both systems are often interchanged, due to the in‐

tegrated housing construction of Haldex coupling and final

drive. Caution must be exercised during maintenance and

servicing, as incorrect fitting can cause the Haldex coupling

and the final drive to fail.

The Haldex coupling and the final drive are one system with

separate oil systems.

-1- Plug for Haldex oil filler hole.

-2- Drain plug for Haldex oil.

-3- Plug for gear oil filler hole.

-4- Drain plug for gear oil.

Further information on arrangement of plugs ⇒  TPI 2017008

Special tools and workshop equipment required
♦ Torque wrench -V.A.G 1331-

♦ Used oil collection and extraction unit -V.A.G 1782-

♦ Oil spill cloth -VAS 6204/1-

– Check for correct filling by raising the vehicle again, and check

if oil has flown out of adapter -A-.

– If no oil has flown out, lower the vehicle again and continue

with filling.

– As soon as oil has run out, hold the oil container below the

height of the Haldex coupling, so that excessive oil can flow

back from the line into the container.

– Remove charging device for Haldex coupling 2 -VAS 6291-

and screw in oil filler plug.

Specified torque: 15 Nm
– Now check the correct oil level at prescribed temperature

range.

– To do this, connect vehicle diagnostic tester 

⇒ page 32

 .

– Select one after the other:
♦ Vehicle self-diagnosis
♦ Running gear
♦ Four-wheel drive with Haldex coupling
♦ 01 - Systems capable of self-diagnosis
♦ Four-wheel drive Haldex
♦ Electrical components
♦ Oil temperature
The oil temperature must be 20...40 °C and can be reached by

carrying out a road test.

– Remove oil filler plug again -arrow-.
The oil level is correct when the Haldex coupling is filled to the

lower edge of oil filler hole or at least 3 mm below oil filler hole.
– Use a new seal and tighten oil filler plug.
Specified torque: 15 Nm
