Got a low pressure warning while driving and the display showed all 4 wheels in yellow. When I got home I checked the pressure with the tires warm and the front two were 36.5 and the back two were 42.5. Recommended is 32/38 cold so I am near suggested cold. Anyone know why this might happen?

did you check the pressure on idrive or with a gauge ?

try resetting the tpm on idrive

This happen to me when I reduced the tire pressures from the over inflated numbers from delivery. If the tire pressure changes from the stored value by a certain percent/value it triggers the warning light.

Set the tire pressures all the way around to the correct tire pressure and reset the TPM system and you will be good.

Mine is at 35 - 39 cold

Mine cold were 34/40, so about 2.5 higher when warm. I got it reset in idrive just couldn't figure out why it came on. I know if one side is 3 less than the other it registers as low or at least that's how my E93 was but the fronts matched and the backs matched. I did adjust them so but that was two weeks ago.

When the tires are cold..just go for a drive and perform a reset. The car will remember the current psi and next time it will warn you when it get too low under that.
