Can you also check one more mysterious washer number 22 here http://www.realoem.com/bmw/showparts...02&hg=26&fg=10
It says install it if yellow or blue dot is presented on mines I found blue dot marked at one of the bolts I guess it has to do something with balance of diff.
Maybe somebody knows where I can find manual about installation of the diff to see what is correct torque of the bolts etc.. Like Bentley manual or something.
