After inflating tires to the proper pressure, you need to driver for a few miles for it to go off, at least that's been my experience. If not, then you can perform the TPMS reset procedure. If that doesn't work, take it to the dealership.

 

i filled mine to the recommended 35psi... its still on... of course i used a gas station gauge to check the pressure... i'll probably get a better reading when i get my air pressure gauge next week...
hopefully the TPMS has not gone bad i also have an 08 coupe...

 

Ok... The tires were cold though, I left my house and was at the gas station within 30 seconds, not even lying lol

 

On my ’08 the manual says to drive at least 16 mph or more after resetting the psi to recommended levels and the light will go out. It’s always worked for me.

 

Nitrogen filled tires is what the dealer gave me when I bought my car last month and although at the time I thought nothing of it, I love it now. It loses air pressure about 10 times slower than regular air and after a month I've lost very little PSI and there has been some cold nights.

Saves you from the hassle of continually filling your tires and no worrying about having flat tires from rim leaks in the winter morning and even air leaks from a nail in your tire deflates slower. Not to mention you get optimal gas mileage and even tire wear because your tire 95% of the time is at the correct PSI between oil changes.

 

just thought i should give all of you an update with my TPMS warning issue... got my air pressure gauge last week and checked my tires... thanks to the crappy gas station gauge the pressure was 40psi on all tires :P so i corrected them to 35psi all around... drove around and the TPMS never reset

so i finally took it to the dealership... the service guy reset the TPMS (no cost) but told me that he suspected a faulty sensor on one of the wheels... the very next day the TPMS warning came back on... so i took the car back to the dealership... turns out that both the rear tire sensors had gone bad... so they replaced the sensors (again no cost) and everything is fine now

interestingly the service guy told me that usually if the tire pressure is low the TPMS light tunrs on solid (no blinking)... but if the warning light initially keeps blinking as soon as you start the car then most probably it means that there is some kind of error with the sensors... and that was what happened in my case... thought that was pretty useful info...

 

Good to know srini... Definitely take that into mind considering snow will be coming soon...
