I'm glad your van is performing well on your ski trips. We had 12 days straight in Val Thorens this year. It certainly tested our van this time round.
Our Dualtop played up this year due to bad diesel! Heat output fell, just like you describe. Our flash code indicated no fuel.
Even after refuelling with good stuff, I had to remove the Webasto dosing pump and put it over the hob to get it working again!
Strangely enough, just like you, we started to get low voltage faults recently. I traced it to a bad common negative connection for EVERYTHING on the left side of the van. I have since rewired the heater to the B2 positive and negative connectors at the CBE panel to reduce the current down that negative cable.
Shared experiences count for a lot on here!
