Unfortunately all that means is that the motor will warm up faster if you drive at moderate speeds rather than letting it idle, it doesn't tell you when it is actualy warmed up.
It's amazing that BMW gives you a MPG guage front and center in the dash which is a waste (what a surprise, MPG goes down when you push the gas pedal down) and no temp. guage.
The MPG guage should be replaced with a coolant temp. guage and there should be a way to see the oil temp. maybe by going into the computer like you do to check the oil level.
Love the truck by the way, by far the best SUV I've had including a POS Range Rover. It's amazing how well a vehicle that weighs over 5000 lbs. handles and moves. It's also been problem free.
The above temp. issue is an issue but overall I'm real happy with my X5.

Amen... Amen..

M's replace that dumb gauge with a oil gauge..... :rolleyes: don't know why BMW insists on putting a MPG gauge in when the computer can give you that estimate.

Cuz penny-pinchers like me care about instant fuel consumption. ;)

I don't understand why BMW got rid of the old gauges, which worked fine for decades. They had the coolant temp gauge, fuel, tach, speedo, and instant fuel consumption gauge (which I sorely lack). They were easy to read, clean, and simplistic.
