I have a 06 b7. When i bought it a few weeks ago used i opened the hood and the engine where it says turbo was shiny like it had been oiled to look clean. Now a few weeks later its still like that. When i put my hand on it oil or whatever it is gets on my hand and its hot. Is it normal? Is this oily substance suppose to be all over my turbo? Its not dripping or anything its just like a gloss
