Sorry, new car and first with iDrive. Didn't have issues with my 135i but would like to know how to manage the M2 TPMS for WGI this weekend.

Yup, 27psi min. My iDrive reads 1psi lower than two of my gauges, so 27psi on my gauge is 26 in iDrive. The means setting at 27 on my gauge still gives me 1 lap or so to get the tire warm and up to 27 in iDrive.
I don't rightly know what the reset does other than the car wants to verify that it's readings are correct making a human add air, measure with a gauge, and reset.
