Post by: Scuba on November 24, 2013, 09:00:45 am: Hello

i am facing a weird problem i have a 2.0 mk4 i've notice that oil is mixing with gaz we have check the car there is no dtc error or any problems as miss fire or anything car is running properly ,just found the oil exciding the limit and can smell gaz.
did any body face a similair problem?
