You'll likely be one of the first to do this! We have some techs on the boards who may be able to supply you a PDF of the procedure.

Any reason why you're wanting to change the diff fluid already?

Hypoid gear oil from sheet 235.7 0.55L.

Take note of step 3 in the PDF, no filler hole.

The complexity and level of specific tools required to work on these cars has eliminated the diy'er, don't you guys agree?
