Thanks @Britprius I've tested all the modes from the climate screen and they all seem to work (air gets blown out of the correct vents). Do you think the noise I here from the centre console might be the electric water pump? Where is the electric water pump located?

Thanks @Farqui. It's going to be too complicated for me to do, I'll get a professional to look at it. If it's gets sorted I'll be sure to post back with the remedy.

Mine also makes a very strange chatter type noise coming from the drivers foot well or maybe a bit more central. The noise is audible even after the car is turned off and the key removed. Could this be a ventilation servo noise? If so, might that be the cause of my cold heater problem?

Did you fix your heater issue? I have the same symptoms where the heater blows cold when the speed drops to around 30mph and the ICE turns off. I'd be grateful of any suggestions or resolution.
