Stupid question for me few years ago.

BUT. Since I have Dooper my exhaust was always clean, without any black soot.

BUT. Since service changed me turbo soot appeared. Sometimes (with full throttle start) I could even see smoke behind.

So, do you have black soot in your exhaust? Answer in the poll, and add details if any...

First diesel car I've had that doesn't cover the exhaust and tailgate in soot :D

Must admit I keep looking at the tailpipe and can't understand how after 24k miles the thing looks like new and I've never ever cleaned the pipe - strange!

03 mcs with jcw. had it when i picked it up with 26k miles. cleaned it out none yet in last 1k miles

03 mcs with jcw could have it. It is petroleum version, I suppose ;)
