Hi

I have an A3 1.9TDI R Reg (1997) which was high mileage on it, It has started making a high pitched whining noise. This only happens at high speed and generally when I am going round a left hand bend on the motorway. If I break the noise stops but when I accelerate it comes back, it also makes the noise in neutral and I think it is coming from the back of the car (possibly the right wheel) I have looked at Pads and Discs and they all look ok.

I have topped up steering wheel fluid and that is not leaking.

Any help/suggestion?
