Hi. I have a 08 plate focus 1.8 tdci and currently have some issue, temp gauge shows around 73-75c while the hidden menu about 88-90c also sometimes needle goes up to 90c while hidden menu shows 112-115c. Other thing it does shows 75ish and after turning engine off and ignition back on goes up to 90 than going back down to 75ish. Anyone had same or similar issue? Dont know if fan kicks in at all.
this is it exactly.

thanks in advance
