My Xf 250 2014 diesel engine fan is on constant and wont turn off .

 

I had a case like this a few years ago with the XF. do you have any error codes? in my case, replacing the fan did not help. turned out to be a faulty motor controller. buying a second controller + coding solved the problem. you should first read the error codes, later replace the fan

 

Therse no codes and everything is working fine . I had three garages do diagnostics one was just an auto electrians and yhey said it leads to the fan being the fault .£685 for a new fan and £300 labour cist to fix it .
