So i know the m5 and m3 share the same issues and sib about the slow, tight turn, rubbing sound from the diff so maybe someone can help..

My car is making the rubbing sound when cold and turning to the right. So im going in for a routine service which includes the diff oil change.

My car is a 10/2008 build and a MY 2009 model.

Is the special diff fluid now a standard item or will they put the regular diff oil in my car again unless i complain and they put the sib special diff oil with additives to stop the rubbing sound..
