There is an audible squeaking/grating noise from the rear part of the car which increases with speed and is quite noticeable. Dabbing the brake pedal makes no difference and the noise starts without fail after the initial 50 yards or so (and only stops when the speed is reduced to walking pace). My local VX dealer thought at first it might be the parking brake, but after a first service today and a two-man road test they lifted the vehicle up for inspection and now believe it might be the differential. Fluid level is OK and they do not suspect the AWD components to be the cause. They have contacted VX for advice and I volunteered to ask the experts on the Forum as well. Has anyone else experienced this?
