Hi, i have a 1 yr old xf r sport. Recently i have started doing long trips in it ans since then the main fan will come on once the engine is upto normal temp. It sounds very loud also. I mean very loud. If i turn off the engine and restart, the fan will not come on for a couple of minutes, but then off it goes again. The car has had a recent service and all coolant levels etc seem ok. I have never noticed this in the past yr and so i presume there is a problem somewhere. Can anyone advise please.
