What a ridiculous system lol.Must've just been coincidence that mine read right at the time (idling in a car park at a dubmeet). I think knowing that isnt accurate is more worrying than knowing the exact temp!
Edit - But that brings up another question.........if its not the temp that ruins the hdi mpg, why is it so poor comparatively?
regards to other question, most likely completely different engine design using unit injectors, HDI on 306s is the first version of commonrail, since then theres been different revisions and improvements, higher rail pressures, piezo-electric injectors and vnt turbos, all attribute to better atomisation of fuel in cylinder leading to better mpg
