Rear diff / Transfer case - front diff oil change

[993turbo]

Hi there,
Im planning to change the oil on my my rear diff (final drive) and front diff/transfer case on my RS6. I think it is more or less the same on the S6.

Does anyone have an writeup on this?

-How much oil in the rear diff?
-How much oil in the front diff / transfer case?

Change procedure? I see a drain plug on the rear diff, is there a fill plug as well or is it a press in prosedure?
What about the front diff / transfer case?

Cheers!

The rear diff has a fill and drain plug. Remove the fill plug before you drain it. It takes a liter.

The front and center diff has only one plug. You need to pump out the old fluid. The plugs are located on the passenger side. Each one takes about a liter. Basically just pump it in until it flows out

Cheers. Did the rear diff.

Will look at the centre / and front diff over the weekend.
