My new M3 is 1 week old. 175 miles on it. 5 speed manual. My TPM light came on and stayed on. I quickly got out to check so it wasn't a flat. I work in an area that has small metal debris, screws and nails. No flat and when I got home checked all 4 tires, they were all 30 PSI. too little ???? It has been cold here in Chicago with temps around 5-15 degrees. I park my 3 in my garage so its out of the weather. The next day the light comes on and stays on while I am on a 20 min. drive then it goes off. It came back on and I am thinking to get it in and have checked out.
Any thoughts ??

If they were at 30psi after you'd been driving on them all the way home, they were probably a couple psi lower than that when completely cold before you started driving. Check them in the morning tomorrow before driving at all, and I bet they'll read around 28psi-- definitely way too low. They should be set at 32-34 psi cold (before driving on them). Then the light should go off

Kinda thought that from some of the other posts. The dealer set it up that, so i will add a bit more.
Cool and thanks.


LOVE THIS 3 !!!!!
