Hello, I drove behind my own G today and am quite surprised that this smokes black when starting up and changing gear from the exhaust. Despite retrofitted particle filter for the green badge! With a vacuum cleaner I would be less concerned here. Here at the CDI I am not sure if this is so normal. I make oil change after Assyst and is used Aral 10-W40. The oil consumption is with approx. 1 liter to 15 – 20 thousand km normal I would say. now 112000 km and is from 01.2004. Why does the diesel smoke?? Is this because of the combustion??? Filters are all renewed!
