Hi guys, Quick question (hopefully) with my S3 I can hear the turbo whistling away when accelerating and hissing when I lift my foot off. Especially noticeable when the windows are down. Didn't think anything of it, but a mate of mine was in the car yesterday and questioned it. I assume it's normal for the S3? I can't remember whether the S3 I test drove had the same noises or not.
