All of a sudden ...

Engine temp has started to go into the red and warning message comes saying high engine temperature and the fan comes on.

It is possible to reduce engine temperature by running the interior heating system on full blast (old skool trick) and when doing this, the engine temp gauge goes back to the regular mid temp level (12 o'clock position).

On inspecting the engine after it goes into overheat, the water reservoir and hoses do not feel too hot. There is no boiling.

When you slowly open the water reservoir cap when hot, the water fills up and overflows.

Is this a water pump issue or a thermostat?

How much does it cost for a water pump replacement?
