Good day everyone. Having some issues in regards to the auxiliary heater in my 2008 sprinter. Was functioning flawlessly for the past 4 months of daily use. I filled the van at a fas gas and think I got a very poor quality tank of diesel. Have been getting water in fuel light and now when I push the button to toggle the aux heater the red light comes on for maybe half a second. No noises from the pump or unit and then the light goes out. Could this be water in the espar?

How much fuel do you have in it? It wont run with less then around 25%
