Hello again Alan,
It seems to be generally accepted that diesels produce much less heat than petrol engines. You say that your coolant reaches only 72 degrees so a functioning standard 88 degree thermostat is never going to open on your engine. So no, I would not suggest that your thermostat is faulty.
I am indeed taking Jim's "driving style/situation" into consideration. He reported low coolant temperature at motorway speeds in November's climate. That indicates over-cooling and that can happen only if the thermostat is faulty.
For many reasons I am not convinced that use of the heater has a significant effect upon coolant temperature. i know that you and others will disagree with this.
I'd rather not become involved in a debate about the diesel when what we need to be concentrating our minds upon is the KV6 of which I do have relevant practical experience.
