TPMS!!!
so for the past couple of days the tpms lamp warning has been displaying on the idrive. i checked the tire to see if it was actually low, it wasnt. it was slightly above 30psi! the reset works for short period and then it comes up again. i know if the sensor is bad the warning lamp is red, is this correct? the error im getting is yellow and display the rear tire passenger side! anyone has come across this... |

Fluctuating ambient temps will cause this. You did the right thing by actually checking the psi rather than the impulse reset via iDrive. I'm willing to bet you fell just under the low psi cut-off. Sometimes my light will go off as I am driving in to work. It sits outside in the sun all day and when I drive home the warning will go off. Seems to only happen on really cold nights that have much warmer afternoons.
I say keep an eye on it, be sure to check the PSI if it goes off again though. Some don't realize that the RFTs, even when flat, don't look flat thus visual inspection alone can't always be trusted. |

I adjusted my tire pressure the other day to be what's on the side panel of the door. (32/38). Is it necessary to do a reset of the TPMS system?

In other markets such here in the Australian market where we use an ABS-based system which compares the relative rotation on the four tyres, if you have made a significant adjustment to your tyre pressures - particularly on just one or two tyres - then yes you should reset the system so it has a new reference to work with.

My recommended tire pressures on the door frame are 32/35 so I would say your tire pressure is low and that is what your sensor is telling you. After reinflating the tire that is low you should reset the TPMS and your IDrive shows you how to do it-simple.

on my sticker it says 32psi and when i checked, it was above 30 psi on all 4 tires even though it was indicating rear passenger tire. i just wanted to make sure rest of the tires had proper psi and no over the psi range. i will try to get a digital gauge to get more accurate psi
