TPMS? Help! Flat tire light going off and all tires have proper tire pressure! Wtf?

I was on my way to work this morning, and my TPMS must have been set off, or something, because now I have the tire pressure light on, but all my tires are fine on air. What could it be? Can I just reset the damn thing?

There is a reset procedure. Search here on E90, or check your manual. I can't remember it off the top of my head.

Also remember that cold weather can set it off. In Seattle we are in the low 30s and my tpms went off.

after awhile the tpms get corroded I dont know how but for some reason it does so that could be it and you might have to replace one of them or like mentioned above cold weather will decrease your psi until the tires heat up good luck

It should be in the menu of the BMW on board computer. Just flip thru (on the left stick) and it should be one of the choices

Did you actually check the pressure with a gauge or just look at it? I had that happen before and thought I was going to see an obvious under-inflated tire. However, everything looked fine (35 series front, 30 series rear). Put a gauge to it and one tire was nearly 10psi lower than it should be.
