View Full Version : Flat Tire warning
05-14-2007, 06:06 AM
I have a 2007 550i. Beginning this past winter, My flat tire warning comes on when I first start the car, If I reset it it went off. The dealer told me it was because of the change in pressure with the cold weather, well it is very warm here in DC now and the flat tire warning comes on for all tires, depspite them being full, and the reset will no longer work. Anyone else have this problem?

I had an issue with the warning, but not like the one you are describing.
Maybe try inflating your tires with Nitrogen (which expands/contracts less I believe) and see if that helps? Many tire centers have it on hand.

I have a 2007 525, live in VA and had exactly the same problem and the dealer told me the exact same story about the pressure changing and etc... In February the TPM went on for all four tires, then I reset it, next day, one tire got flat. I took it to the dealer, they told there was a nail. Maybe two weeks after, the TPM went on again for the both rear tires. took it in, nothing happen, they checked the tire pressure and everything. Just this month, it went on again, they said I got a nail.
I am really tired of this tire thing!!!!!!!!!!:dunno:

I had this issue multiple times. This past Fall-Winter, the sensors went off 4 or 5 times over a two-month period. Apparently, the sensitivity was too high & the system was reprogrammed with some other modules. According to my dealer, my car's frequency was an anomaly, but there is a bullentin on the issue. While weather changes can be part of the problem, I would have it checked if it is happening frequently. For me, the computer update solved the problem.

Now that the weather has warmed up down here, I get it every single morning on all four tires. I've driven all my life without a tire pressure management system and survived. I wish I could delete this thing.
