All-wheel drive coupling: changing oil
Note
♦ On vehicles with all-wheel drive coupling the drain plugs and
sealing plugs of both systems are often interchanged owing to
the integrated housing construction of all-wheel drive coupling
and final drive. Caution must be exercised during maintenance
and servicing as incorrect fitting can cause the all-wheel drive
coupling and the final drive to fail.
♦ The all-wheel drive coupling and the final drive are one system
with separate oil systems.
♦ -1- Sealing plug for filler hole of all-wheel drive coupling oil
♦ -2- Drain plug for all-wheel drive coupling oil
♦ -3- Sealing plug for gear oil filler hole
♦ -4- Drain plug for gear oil
Special tools and workshop equipment required
♦ Temperature gauge - VAS 6519-
♦ Torque wrench - V.A.G 1331-

Ensure adherence to prescribed temperature range during oil
level check if oil temperature was not within prescribed tempera‐
ture range of 20 °C to 40 °C when topping up oil.
The oil temperature can be measured using temperature gauge
- VAS 6519- .
If the oil temperature is not between 20 and 40°C, adherence to
prescribed temperature range must be ensured by running gear‐
box warm or allowing it to cool down.
