Well the specs were spot on, they literally both switched off at -40 then back on when they drove a few hours slightly warmer, at least the van engine didn’t cut out, phew!
So if your going to the artic in winter mount inside the van..

Was it the actual heater / fuel pump that gave out at -40 or was it simply that the diesel was too thick at that temperature for the metering pump to shift enough fuel to keep the heaters going?

I think it was the heaters reached their lower cut off temperature, the engine still ran on same diesel, although a bit rough , when I get home I’ll find the video and post.

It would be most likely that the ecu temperature sensor sensed the low temp and therefore shut it down. If it were thick diesel you would expect to get error codes due to flame failure or something else.
This ecu from a Webasto 3500 ST appears to be set at minus 39.9 degrees not minus 40!
