Just the other day i noticed a funny noise coming from the car. I turned down the radio and had a listen to it a bit more. If the car is say at 3000rpm and i take my foot of the gas and let it slow the whining noise starts. Its doesn't appear when i accelerate. It seems to be getting louder day by day. Is this the wheel bearing? Should i be worried about anything else? I'm booking it into Audi tomorrow when the service dept is open. Thanks in advance!
