IMPORTANT: If oil is filled up to the lower edge of the oil filler opening, the front axle differential would be overfilled and in rare individual cases oil could emerge from the ventilation opening on the front axle differential.
After draining front axle differential oil or when carrying out the initial filling of a new replacement front axle differential, the transmission must be filled with 600 ml oil.
Use only the APPROVED FRONT AXLE OIL in the front axle differential.
Failure to comply with this requirement will result in serious damage to the front axle differential!

NOTE: Only change oil when front axle differential is at normal operating temperature.

The front axle differential is subject to oil filling over its lifetime. An oil-level adjustment is not needed during the service. If there is a visible release of oil or after a repair to the front axle differential, follow the instructions in "Front axle differential oil replacement" .
