Anyone know if it’s normal for 1.5 dci to pretty much always run at about 76C? I bought car (2014 model) in August 2019 and noticed, as have others, that temperature gauge sits on bottom reading almost all the time. Very occasionally on a hot day going up a steep hill it will go to mid point but return to bottom reading very quickly. I took it back to Renault dealer thinking stuck open thermostat but told that it was operating normally and they were all like it. It’s bugged me as only getting 48 to gallon which seems lower than it should be? I bought a Bluetooth obd2 reader recently and that shows that the car runs at approx 76C even on a hot summers day. I can get the tempearture to rise when stationary by turning off air con and rev to 2500rpm for a few minutes. After a while temperature rises and at 80C the gauge goes to mid point and at about 82/83 cooling fan comes on. Still wondering if I have faulty thermostat? Any thought?
