I hope this isnt what I think it is, but my S3 just started making a strange whirring/whinning type sound at very low RPM. When im pulling off slowing in traffic and change to 2nd i can notice it. When put the engine under load I couldnt hear it but think it come and went briefly at one point. Could this be the start of dreaded turbo problems?? If so this is not a good weekend!!
