Since I've had the car (over a year), I think I have has a slight problem with one of my rear brakes….
There is scraping noise coming from the rear when driving at low speed -
The noise sounds similar to like someone sharpening a knife on a sharpening block - so it's not constant, but increases in frequency and pitch the faster I drive - and is very much in synch with the rotation of the rear wheels… at about 5mph I can hear it "whish……………....whish………………...whish….", the faster I get the faster it also gets….. It's not exceptionally loud and can't hear it by the time I'm up to 15mph.. And under normal driving you can't hear it at all….
A further bit of info that might help you clever chaps diagnose this…. If the car has not been driven for a while - say a week….. And I try to pull away under idle rpm (it's a DSG) the car moves as if to go then stops - because something has seized (in the rear wheels/brakes??…) and I have to give it a little throttle for it to "break" free of whatever has seized…. And it's a definite and sudden "breaking" free of whatever is holding it back… rather than moving against gravity - could this be related to the problem above…?
Thanks for any input guys. Will get the brakes checked out - but want to go there with a bit of info to give the mechs.
