Frequently asked questions
Why does my diesel heater keep shutting off?
Carbon buildup, a tired glow pin, or a weak fuel pump are the usual causes. We decarbon and test each part so the heater relights and holds steady heat.
How often should a Sprinter bunk heater be serviced?
Most benefit from a decarbon service every season or so, sooner if you run it a lot. Regular use around Riverside winters keeps the burner cleaner than sitting idle.
