Only carry out the oil level check at interior temperature and not on a rear axle center assembly which is at operating temperature. Oil which is otherwise needed might flow out when the rear axle center assembly is hot.
1 Clean area around oil filler plug (50g).
2 Unscrew oil filler plug (50g)
3 If necessary collect which runs out and allow to run out until the oil only drips out of the opening.
4 Check oil level.
The rear axle is correctly filled when the oil reaches the bottom edge of the oil filler hole. If necessary refill with hypoid gear oil.
The fully synthetic oil can also be used without reservation for rear axle gears manufactured before 04.11.2001. Mixing old Universal hypoid gear oil and the new FE hypoid gear oil does not lead to any impairment of the basic functions such as wear characteristics, leaktightness etc. on the rear axle gear, but should nevertheless be avoided on account of the better fuel economy.

7 Screw oil filler screw (50g) into the rear axle center assembly immediately and tighten .
