2013 TDCi Engine Temperature Varying

[AlCan]

20-21°C ambient here today.

Just did a quick shutter test, warming up lazily putt-ing about some local streets at 40-50k's.

Never got to see when it started to open, but at the 60° line, was already half open. Stayed about like that until 75 or more. Don't know exactly when, but after thermostat opened, it was fully open.

I suspect the overcooling after thermostat opens occurs when the shutters move to fully open, but the lazy stat doesn't partially close up again. BUT, I can say, better than not opening! Reading around FF, I can see lots of people have reported crap t/stats. Guess I'll just have to do it. But test the new one first.

Does anyone have a map of how the shutters are supposed to open and close versus engine and ambient temps? Or are these results close enough?

Also, anyone know if the AGS (I think - Active Grille Shutter/System?) uses the Coolant Temp sensor or another one somewhere else?
