I have had a noise from my S3 for a few months now and have checked everything. Its under boost and sounds like its coming from behind the glovebox. I have now checked the Turbo and there is a worring amount of horizontal play down the shaft. Like 3mm maybe more. I have no smoke nor am i loosing oil. It does still boost but does not feel like it used to. Can anyone suggest a company who can rebuild the turbo for a reasonable price or has anyone got a used K04 Turbo Unit?
