Hi, I own an Audi A4 3.0 tdi Quattro, My car is full serviced by professional audi agents in my country. I have one problem, My car smokes really bad. Whenever I drive there is a cloud of thick smoke behind me, But all is Ok, I changed all filters and drained the oils out but no change. What could be the problem?
