There is lots of data that can be summoned on the little temperature display.
I use it to see the real mph (spot on agreement with my sat nav when the garmin is on).
One car I used to drive had an oil pressure gauge and after 9 months the oil used to go off, reducing pressure to the bottom of the display. I'd like to see if my main dealer oil in the GTI is doing the same and perhaps a year is too long between changes for a car thrashed around B and C Lakes roads. It certainly uses oil when driven hard.
Does anyone know if oil pressure can be displayed?
