I think you'll find the gauge in the E92 measures
oil temp, not water. Oil temp does not fluctuate like the water temp. My understanding (as has already been said) is that water temp is not displayed because the water pump speed (and thereby engine water temp) varies according to driving conditions. So the gauge would be varying wildly and causing owners unnecessary panic.
