Who starts without waiting for the glow plug light to go out? What happens if you just jump in the diesel and fire it up? Is there more soot produced during start up and possible senor fowling? I'm just starting to learn about diesels and don't have a clue as to the answers. Generally I use remote start and the car is running before I open the door. It's been 9 months and 27,500 miles CEL free. any thoughts
