I had heavy clouds of smoke coming out I figured it was my Turbo got it replaced and Smoke Stop but started smoking again but a little white smoke with oil coming out. I have all my fluid in my reservoir but can see that I have a mixture of oil with my antifreeze in my reservoir still full no leaking from it I was wondering can a problem comes from the PCV valve because that was the hints I was getting from other people my car started to shake a little and my steering wheel became hard to turn need some information about it please And what problems can a Turbocharger causes on the rest of the car. it Been three days now I go get my car tow back home and now I have low coolant in the reservoir what signs are there my car still have the same original Audi parts on the engine and hoses never been repaired by the looks of it or certain items haven't been changed
