I have been experiencing something strange with my x-5 and I wonder if anyone has any explanation or has experienced the same.

The temp indicator usually went up vertical (pointing at 12) after reaching normal temp. Winter (in NY), summer, AC on or off, etc. Always the same.

Today, the temp indicator stayed all the time within the two middle marks (pointing at 11 and 2), leaning always toward the coolest side. I do not think it may be calibration as, when stopped with the car at idle the temp indicator went back to vertical, going down again when moving.

Again, it has always been within normal operating temps, but I find it strange it seems to be working cooler. The ambient temp in NY is cooler but not less than 55 where I live.

In a few words is kind of the opposite of overheating. Car seems to be running normal otherwise

Any ideas what can this be?

Thanks in advance for your responses.
