Where are you taking your readings from Brian?
I also have the digital display on the S, it's the same as my old E63s one but it doesn't show a water temperature anywhere as far as I know?
The only coolant temp on mine seems to be at the base of the tacho, dependant upon which display you have showing.
Number 4 on the above image from my manual.
This is the temp display I have: -
Top is oil temperature, lower is transmission temp.
I can't get to the car currently as it's on the lift in the garage for the winter.
