My 2000 audi a6 2.7t just started smoking (real bad) out of both
exhaust pipes. It also sounds like the waste gate is partially open
(like a small exhaust leak). The oil is 3 weeks old (synthetic 5w 40)
as is the filter. I am not getting any engine codes and the car seems
to run OK. Not that I took it too far when I saw the smoke. Could it
be the turbo? What would cause that to happen? Too lean a fuel
mixture? Just age?
