I remember taking my car in last year for the rubbing diff noise and they added some uber expensive friction modifier/fluid..
Curious if the Dinan diff has this issue and if it uses the standard fluid or special fluid.
On their website they recommend BMW synthetic diff fluid #83 22 2 282 583. Not sure if they recommend using the additive/modifier if you have diff whine but my guess is they would suggest adding it...
