I have a 2004 W203 C200 Kompressor which has done 5000 miles.

I have recently noticed that when starting from cold there is often a puff of blue/grey smoke from the exhaust. Is this normal, i.e. unburnt fuel? The inside of the tail pipe is black.

Has anyone else noticed this with their car? My previous cars didn’t do this to my knowledge.

Peter.
