I have a 2006 2.7 diesel, sprinter it smokes grey revved wont stay running at idle more than a min or so, and has 140,000 miles on it I think injectors but want to know for sure before ordering as to the expense. I wanted to also note that the pcv seems to be backed up a bit as she was losing smoke and a bit of oil spray from the dipstick.
The engine warning light flashes every now and again on my 2004 Mercedes Benz Sprinter diesel automatic. The van drives just fine but does seem a little bit more sluggish than usual. It tows a van that weighs 2000kg. This problem also only seemed to start after I refuelled.
