Hi can anyone help i seem to be banging my head against a brick wall with this one. I bought the can with 40k on and now has 68k, and ever since i bought it there is a high pitched whistleing / squeaking coming from the front of the car at motorway speeds. It cant be brakes as the pads and discs have been replaced, doesnt sound like a metal squeal if that makes sense and it doesnt do it at lower speeds in a higher gear which would rule out belts, dealer i bought it from couldnt rectify and its got me baffled any ideas would be appreciated.
