I had a similar problem with the truma 6002 boiler on my previous van....

Light a few burners on the hob, then start the boiler, if the hob flames lower when the boiler is firing up it could be the regulator.

I had a problem with mine red light came on.Traced it to loss of 12volt supply to truma.Check when boiler fires up that voltage does not drop to 4volt.It was the output from the schaudt unit that was faulty.

We have just had that happen to us....Clive already on his way to Italy, had to turn back. Took the Hymer into Brownhills in Swindon. What a waste of time. They told hims it was some sort of problem, so to save time he drove up to Truma, got the spares, and brought it back to them....624.30 later, they still had not fixed the problem. Needless to say, Clive brought the MH home and got a brand new Truma heating system for 890.00 and fitted it himself yesterday. The kitchen looked like a workshop....but hey, he is on his way to Italy with everything working! Well done to him!!!

When we had a simialr problem it turned out to be a faulty gas regulator. The cooker rings still worked but the heating failed so I guess the pressure was insufficient for the greater load of the heater. The regulator failed due to a build up of oil residue from the rubber connecting hose (a well known problem) so we had to install a steel connector as well as a new regulator.

Not that this will be much help but as others have said there seems to be two simple issues that cause the red light to go on: lack of voltage and low pressure on the gas. In our cold weather we have experienced both. The hob works under low pressure but the heating won't come on. Two things have caused this, a summertime bottle of gas that got changed to propane and an empty bottle. The electrical problem was just due to a nearly dead battery. So the conclusion is to check both before looking deeper.

red light

I totally agree loss of mains power when on 240 will cause the red light also

we need more details before a conclusion of a non expensive type can be reached

Truma

I also have used the UK Truma Importers at Derby. Excellent service everything taken out of the van checked and reinstalled in a morning and as I recall under 100.
