Exhaust smoke
I just got a 2006 Audi a4 that's basically set up like an s4. It has a magnaflow exhaust and it doesn't smoke when I start it up or when I'm driving. It only smokes every once in a while when the car comes to a stop. When it does happen a lot of whitish light grey smoke comes out. What could this be?
