But I'm pretty convinced that, at least mine with the 6WB cluster, is a dummy gauge to some degree. I have never seen it move from the middle when I know the temps fluctuate based on normal driving conditions, and on top of that it sounds like BMW does some magic with how the cars allows temps to increase and decrease based on how you're driving.

Will positively guarantee you can't get 7 quarts of oil up to temperature in 2 miles even in Saudi Arabia.
The water does come up to temperature quicker for the heater then the N54/55 because the closed deck block has a “heat management module” on the B58, which is mechanically powered directly by the crankshaft through a serpentine belt. Inside the module, coolant flow rate is adjusted by a rotary valve
