VVBK Diesel Heater

Raw footage, Unit worked like a champ for 3 plus months. Comfortable in the Sprinter... keeping systems from freezing during the build.

Suddenly started shutting down, Codes 19, E4, and fuel questions.

Because of weather, and location, a bit of work to get to.

Think the atomizing screen, glow plug and burner chamber might need to be cleaned out.

Murphy's law....
