Basically the exhaust on my TFSi FR usually has a coating of black soot on the bottom portion of both the exhausts every day (I do approx 86 miles each day). The amount varies depending on how much I use the Go Faster Pedal ( ). When I wang it open the soot covers most of the bottom half of both pipes. Not having owned a performance petrol before, is this normal? (I came from a Golf Mk V Diesel GT - where the exhaust was hidden). A neighbour of mine has a diesel FR & I never notice any soot on his exhaust (when I kind of would with a diesel) so should I be worried, or is this completely normal? Excuse my ignorance!
