Rubbing Noise From Rear Differential When Turning on BMW M6

During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.

2007 BMW M6 62,400 mi,
Within the past year I have had to replace about $20,000 worth of parts on my 2007 BMW M6. 1) Oil Engine Cooler - $1350 2) SMG Gearbox - $6100 3) DSC Module - $2000 4) DSC Hydraulic Pump - $3900 5) Rear Diff - $4700 BMW did offer Goodwill Assistance for numbers 2&3 in the form of a 50% discount. Numbers 4&5 have yet to be fixed. I am waiting for BMW to offer assistance on this one as well. Don't know if it will happen. Anyone contacted their Attorney Generals for Consumer Rights Protection?
