I let air out of the front passenger side and once it got to 27psi it displayed as low on the iDrive screen. The center gauge cluster showed the tire light but had no indication of which tire as I previously mentioned. I filled it back up and it returned to green once it got back above the 35psi setting. Pics attached.

Question...the recommended cold pressures are 33psi fronts and 39psi rears. Should I follow this exactly or is 35psi fronts and 36psi rears sufficient. Will it noticeably affect anything? Thanks.
I would run the the tires almost 2-3 psi below recommended (if its snowing you get a bit more traction area).
