I forgot to say that the voltage across the battery when the engine was running was 17.8V.
That is far too high. I would recheck that voltage with another meter, and if confirmed, it would suggest the alternator's voltage control pack is faulty.

Not necessarily on its own.Would a fault code get flagged if the alternator was supplying too high of a voltage?
I've checked the battery voltage, while the engine was running, with a better quality multimeter, it says 14.48V, no fluctuations.
I have thrown out the other multimeter, and I'm going to buy an even better quality one, that I know I can rely on (i.e. not some no name brand from Ebay, but from RS Electronics or some other proper company).
I have just tried to find the boot switch which tells the car the boot is open, but for the life of me, I can't find it. I have removed the plastic cover inside the boot lid, and I can see the inside part of the boot handle, but I can't work out where the switch is.
All the videos I can find online show a switch that is somehow attached to the boot handle, but these are for more recent models of Kia cars, mine is 2009. I don't see how a switch on the handle can be telling the car that the boot is open, since the handle will be in the closed position when the boot is up and open. I presume the switch/sensor I am looking for knows what position the catch is in, because that is either 'locked' or 'unlocked'.
It fits behind the boot handle, so it senses when the handle is pulled open - but what does it do then?
Hall sensor effect.Yes, but what does it actually do when it makes the circuit? What happens in the car electronics? How can it tell the car that the boot is open, and thus cause the light on the dashboard to come on?
