I'd have to imagine its a sensor issue?

Assuming the vehicle is warmed up, the Coolant Temp is a little low as well. How's your fuel mileage been? Mine is tracking around 77-81 Degrees C, and my mileage seems down. Could be that it is winter, or could be time for a thermostat..

Have to wonder if that would be covered under your CPO Warranty as well. It seems pretty universally accepted around the forums that coolant temps running under around 82c lead to decreased fuel economy and early failure of glow plugs and sometimes even the controller module. My understanding is that Coolant temps should run around 88c to see the best efficiency.

But I'm guessing that if there is no check engine light, BMW doesn't consider it an issue..
