My TPMS on my '07 Cayman is acting all weird. Over the last couple days it's strarted saying 3 of my tires are low on air. When I check with an independent gauge they're all fine. No pressure loss at all. What's going on?

 

you could try a large tire store and see if they can reset the tpms for you with their tool. try over inflating ? other than that......dealer

 

Try changing TPMS setting to different size tires as well. Overinflating sometimes "tricks" computer. My 07 Boxster went thru this and Porsche changed all four TPMS (CPO warranty) free of charge

 

'07...batteries failing???

 

i thought that too but 3 at the same time ?
