    Gearbox oil needs to be 75w90 fully synthetic, I used the Motul stuff and you need 2.6 litres.

    there is no Audi service schedule for diff or box (which is stupid IMO)

    both diff and the gearbox require 75w 90 fully synthetic gear oil, but i think its a GL4 spec for the gearbox and GL5 for the rear diff. I used silkolene SYNTRAN SYN5 fully synthetic GL4/5 gear oil, got it from opie oils
