Checking seals and sealing joints

Check the following seals and sealing joints:

• the seal for the input shaft
• the seal joint between the coupling (Active on Demand Coupling) and the rear axle
• the seal joint between the control module and the housing.

If there is oil leakage from the bleed hole:

Remove the level plug and top up with oil, P/N 116 1329. Fill until oil escapes from the level plug hole.

Then drain 0.25 l of oil. Install the level plug.

Remedy any leakage.
