The problem i had was my car ran rich in open loop for four months while i waited for it to become fall and i couldn't get cabin heat with no warning because the 3-position non thermometer.

They put an actual thermostat for oil on wife's f10. It's moronic to have a gauge that looks like a thermometer but isn't.

Hear is a perfect analog:

So BMW might decide that it would be best if the speedometer would show 70 mph when there actual speed was anything between 50 and 90 mph.

Then would show 120mph if you hit 75 mph.

This is how the non thermostat gauge works. It's really stupid.

The needle should not show normal temp unless the engine is warm enough to operate in closed loop.
