See other recent posts on this subject including my own recent experiences.
My dealer insists VAQ is a Borg Warner sealed for life item and does not appear on any service schedule.
Therefore they won’t touch front diffs unlike Haldex.
Their workshop techs confirm this.
As far as I’m concerned, they will continue to service the car and I will continue my VW extended warranty.
Maybe I’m wrong but “ if it ain’t broke, etc”
