TPMS - which tire is low 06 550

Is there anyway to know which particular tire is low in pressure when TPMS throws the generic warning? Any s/w update to fix?

I've had an issue with the valve stems becoming loose from the rim, first time it was the front passenger, then it was the front driver. Both were easily fixed with tightening them with a deep socket.

The light comes on on the dash, but there was a notification on the idrive screen telling me which tire it was.

my idrive doesn't give any tire specific info except to drive carefully within safe limits if RFT etc...i wonder if there is any s/w update available to have tire specific pressure alert available....

I think it has to do with what year your car is / what version SW you are running. My 08 also will show what tire is low, however, it does not give the actual pressure, only that it is low. In fact, when the alert comes on, it states "Left Rear Tire Pressure Low" or something to that effect, rather than just saying "Low Tire Pressure".

Mine too. Remember saying which one is trouble on the iDrive screen. Just add more pressure and it should go away!
