When the diesel engine goes into dpf regeneration mode, the cab of the vehicle fills with unpleasant fumes that smell like evaporated diesel fuel or other noxious substance that is irritating to mucous membranes and may cause health issues. The problem is worse when the vehicle is at low speed or in stop-and-go traffic when exhaust fumes are able to collect around the vehicle. The most recent instance occurred in a drive-thru line at a fast food restaurant, and was so pungent that I was forced to abandon the line, park the vehicle, and evacuate myself to fresh air.
