Webasto aux heater trouble

This van was in our workshop to have a look at the rear aux heater. The heater is a Webasto that uses fuel to a heater underneath the vehicle.

This is the control on the dashboard. The green light flashes a code to help diagnose the issue.

The flash code on this vehicle told us that the system had shut down. So we had to perform a reset before we could proceed further. Once reset a code for fuel supply flashed up.

With accurate wiring diagrams we could trace the wiring to the fuel solenoid and found that there was a cut off switch circuit fault. We managed to repair the fault and confirm a fix with our thermal camera
