Low tire pressure alert, but cars tire pressure is fine??

pikemike420 · 12-06-2010, 06:16 PM

My tire pressure alert came on this morning, but when I checked, all 4 corners were fine. I added a little air just to be sure, drove to work, and it is still on. Should I be worried.

Factory wheels with factory runflats.

sometimes cold weather can affect tire pressures. reset your tpms and monitor your tires closely.

Also, you'll have to reset it to get the warning to go away, it won't just go poof.

How do you reset?

drknight · 12-06-2010, 06:44 PM

if you have i-drive you reset tpms through there. if no i-drive im not sure.

There's a way to do it with the BC controller, i'm not sure exactly.

A reset at the dealer takes about 2 minutes though.

Reset it. Its in your owners maunual, for both idrive and non idrive.

My TPS came on this morning as well. One of the colder days we have had this year. It usually happens when it gets cold

Mine came on too a few days ago after a temperature drop. All tires checked out ok. I'm just going to reset it and monitor them over the next few days

Must be contagious . . . My TPMS came on last night for the first time also. I'm sure it's because it got very cold here and the car was outside. I added some air but the tires were only a couple of pounds low. This morning the TPMS came on and I reset it through the iDrive. Problem solved.

For me, the warning went away on start after fixing pressure to the recommended cold weather numbers.

ThreeseriesFTW · 12-30-2010, 11:30 AM

What are the recommended cold weather numbers?

nelnelxd · 12-23-2011, 02:05 PM

this is happening to me too but when i reset it says warning tire pressure low. Does anyone know how to fix this? I am thinking of just over inflating it by 10 psi cold or something. the warning annoys me.
