On our 2009 Mini Cooper S, the TPMS is indicating that all tires are low (red warnings). I've confirmed that they are all fully inflated. Since they all came on at the same time, I'm guessing that points to a failure with the antennae that receives all the signals from individual wheels. Does that sound like the most likely issue? It looks like the antennae is about $85, so I'm a bit hesitant to guess too much.

Autozone scanned for codes but nothing came up for the TPMS system.

I'm swapping the car's 2nd replacement thermostat in this weekend. The wife absolutely loves driving the car and I love not having a car payment, so I'm willing to continue to keep this high maintenance girl going!

 

did you do a full reset per the owner's manual?

this happens to me regularly due to ambient temp changes but a full reset always clears the warnings .... till the next season change!

 

I'll give that a try! It would be great to fix that problem without any cost.
