I was driving around my 2007 Carrera S like i normally due and randomly my tire pressure sensor decided to go off. I took it to my tire place and had them check the pressure but it was fine. what should i do to get rid of this?

 

I would check the batteries. They are probably bad. They are not cheap either. I'm running Nitrogen in my tires to keep the pressure more consistent, which I won't really see until summer when the temps can go up a lot with hot pavement and ambient temps.

 

you may want to check TPMS. probably out of battery.

 

where can i buy these batteries? and how can i have them changed?

 

Batteries are not replaceable - you have to replace entire TPM sending unit in the wheel. Dealer can use one of his electronic tools to tell you if it's a battery problem. If one battery is bad it probably won't be long before the others go so you might want to think about replacing all 4 sensors at the same time.
