    What should go in my rear diff? Better change it before it runs dry.

    Yeah agreed. Whatever you do don't get it from Audi. They specify it as "axle oil". Cost 40 bloody squid for 3 ltrs! I almost sh*t myself!!

    craigs had been leaking for ages, i had half a litre left over from doing my gearbox, and the half a litre was just enough to fill it up.

    Went to do it tonight but couldnt get the filler plug out. Ill need to get a proper allen socket and try a littlr heat on the diff housing then it should go. I think its not the best head on the plug as the allen key didnt fit perfect in it so i hope it doesnt round off.
