Chris, you said "The evidence surely points to a problem with the expansion vessel or its connection, but the poster doesn't seem to be willing or able to be very systematic about testing it."
Do you mean that he seems unable to explain clearly what he is doing?
Or do you mean that I am losing the track of whats happening with his boiler? ( From what is being posted thats quite likely )

When you have pumped the expansion vessel up to 1 Bar with the system open to the air, keep the air pressure guage on the vessel and repressurise the system to 1.5 Bar. See if the air pressure increases to 1.5 Bar as well
yes it does rise when i do this

Good in that case we have eliminated a blockage between the boiler and expansion vessel.
Next time put a little soapy water on the air valve after filling it to make sure its not leaking air.
Are you filling the boiler from an external filling loop? If so are you removing the flexible hose after filling?
Professionals, its just possible the DHW HE part is leaking into the system but why at so high a pressure ??? Overnight ???

It is not consistant to have 1 bar at the exp and 3.5 on the guage.
As its venting then I expect it REALLY is 3.5 Bar !!! yet he told us the mains water is apalling and only 1 Bar.
Lots of inconsistancies here.
I think an RGI is needed to visit and assess the situation properly!
But NEVER give UP.
