Not sure whether I like or don't like the sound that my S3 (09 reg with new brake pads) makes when accelerating…usually when it gets by 3 revs or so I get a 'chhh' sound as it sounds like air is released, from where I am unsure as I am not very technically savvy when it comes to the S3 yet. You can also hear the sound of air being released when it goes over any sort of bump e.g. a speed bump. I initially thought it was cool, but going around town it can sound a bit weird going over speed bumps and also just putting the food down slightly when not even going fast. Is there a way to reduce this sound or even eliminate it, or am I stuck with it? it's not a massive problem and hardly as though I can't live with it, was just curious more than anything.
