I would have thought diagnostics would be the first step before removing anything.
They spent a few hours on that so far

Diagnostics = plug in a diagnostic computer and read the codes, not take the thing to bits in the hope of finding a problem or chuck parts at it hoping that by luck it might fix it.
There were no fault codes
They tried quite a few things apparently

Maybe they don't have the correct diagnostic equipment
Check and see if the hot water is reaching the heater pipes that go into the bulk head. If it's is then it's a failed hot/cold flap. If not then as said it could be the aux water pump that's failed if it applies.. Over complicated...

On the earlier l322 there is a valve block with solenoids on to divert the hot water in to the cabin its is known to fault resulting in no heating inside.
hi mate
is the kind of thing, alas don’t know if it’s exact one required in relation to the vin code

Indeed a great call as admittedly seeing it more and more on the discovery 4’s called a 3 x way park-heater valve where it also stops heat getting into the heater core when they fail

Yep that looks like the kiddy there was a guy a few months ago that had that seized on an l322.
many thks and indeed I’ve only become aware of those kind of things from D4 owners where theyve also stopped heating getting int9 the cabin
Looks like the solenoids fail preventing flow from the ports as I think they work by heating the engine block first then the cabin after , also some having a remote in order to preheat the engine before getting into the vehicle
thks again as always good to learn about other things
