Ford Ka cooling fan/warning light inop - Andrew Moorey (Tune-Up)
Fan cut-in temp is 105 deg C. Fiesta and Ka suffer from poor sealing of radiator cap resulting in the water boiling at, surprisingly, 100 degC. I replace the caps at each main service. Inspect the top of the neck where it seals against the gasket in the cap. I have seen several with a nick out of them which again causes overheating and coolant loss. I dont think the adaptive learning strategy applies to the coolant temp sensor but you could try disconnecting the battery for a while to reset any adaptive values.
I trust you have replaced the thermostat?

Simplicate and add lightness!!
