Well, I just cleaned my intercooler and instead of green goo I find plain old black oil, quite a bit of it. And, I am now getting a high pitched whooshing or whining sound at moderate to full boost, particularly at low rpms, sounds louder on the passenger side. I bet my turbo is on its last legs. Never made any sound before. No codes at all. The car otherwise drives normally and has lots of power.
