I have a Pollensa 1.9 turbo having come home after a run out parking on my drive turning engine off , it had cooled down and without anybody near the vehicle the engine cooling fan came on of its own accord. Can anybody give me a clue as to the reason for this I assume it may have something to do with the thermostat???

Correct, residual heat from the engine raising the water temperature around the thermostatic fan switch, which should be set at around 90C IIRC.

I assume you follow the usual recommendation to let the engine idle for a couple of minutes before turning the ignition off, to let the turbo cool a bit?

Yes always allow engine to idle allowing the turbo to cool down, but I walked out to where vehicle was parked the day after it had been used when everything must have cooled down to find that the cooling fan had started running without the vehicle being touched!!
