Back with the OPC, annoyingly in the correct range when car at operating temp. They are too keep overnight and see where it settles when cold. My experience since the coolant pipe repair has been for it to be ok when warm but drop below minimum when cold. Interesting comment about tank having a crack!! They have had my car on the ramp this morning and no obvious signs of leaks. I think it's an airlock, never had before despite my car having had its coolant drained and refilled before for radiator swap and I think it's required for a water pump change as well.
It's a frustrating fault, to be honest I need to have stock of some coolant so that I can manage the level if no fault found at OPC
