got into my e46 m3 and noticed that this strange light was on turns out it means i got a flat tire, but i didnt i even inflated the tires some more and the light still never came off...? WHATS THE DEAL HERE?

PS. my car is in a heated garage...so i dont know if the weather plays a factor...

Not necessarilly a flat tire but a tire that's under inflated. Take out your tire gauge & start checking.
Yes, I think the weather is a factor in this case since I also have to do this to my tires when I drive it for the 1st time after storage.

yah no worries, just check your tire pressures... my sensor usually comes on when suddenly it gets extremely cold out... remember, extreme cold temps affect tire pressures.. its a great warning system as we should be checking our tire pressures regularly anyway.
