i purchased my used s3 about 2 weeks ago and notice everytime i accelerate smoothy i can hear a annoying sound which is quiet low to be honest and many passenger cant hear it but because i drive it everyday and i notice it when i push the pedal down and it ruins my experience a little but i dont know if its a normal sound like its a turbo or a fan or something but it only happens when accelerating , if you accelerate hard then the sound is covered
best way to explain the noise its like when metal lightly touches another metal while is moving for example low brakes pads and the plates are rubbing against the disks which create a sound but not as loud or as harsh as that
i was going to take it to audi but because its very low i dont think they will be able to hear it unless they lived with the car for a week or 2....in fact i dont think i am doing a good job of explaining it to you guys well too lolololol
