    It is not unusual for the TPMS to be triggered by a large temp drop. When the tires are filled when it's warmer such as in the summer and then a cold snap hits the pressures can drop a bit. I think the trigger for the TPMS is 4lbs.

    Yup, same thing happened here. I was home for Thanksgiving driving my mom's R56, and the tire light went on when the temps dipped down to 26*F. The reset is a pain in the butt to find, but if you press the button on the end of the left stalk, you can cycle through the menus and find it.

    Mine resets itself when they warm up or if I top them off....

    Most retailers put green caps on the tire stems when they fill with nitrogen, as a warning.

    However, considering the air we breathe is about 80% nitrogen anyway, I find it hard to believe that it really matters.

    I would go with the air pressure recommendations in your owner's manual, rather than a SWAG....

    I think the formula is 1 psi loss for every 10 degree drop in temperature.

    Thanks for the quick replies. In my oringinal post I meant to say I topped them off to 38lbs as prescribed by the Manufacturer. Luckily I was able to find the reset with ease. I drove the Mini about 10 miles after the reset and so far all is well. Money is a little tight around holiday season and it would really sux to have to replace an almost new tire.

    I am going out of town for a week on business and almost want to reschedule because I wont be able to drive my Mini this week. I definately have the Sickness.

    All you are doing when you reset is setting the normal pressures, then deviation from that is what triggers them.
