HI This problem is intermittent.Fan comes on at any time,car starts to run sluggish as if it is in wrong gear.If i pull over it smells of burning rubber.Sometimes the oil service light comes on even though a service is not due.This last's for about 15 minutes then fan goes off and all goes back to normal,if i turn the engine off whilst this is happening it seems to reset and go back to normal,however if i do this it happens again very soon after Regards, 2008 58 Reg Ford Galaxy Edge Auto
