TPM

[skarletknite]

today had a message saying my tire pressure was low. stopped and checked it myself, did not notice lower pressure or any visable damage. pulled into a tire place as i was about to go on a long trip(of course bmw centers closed on sundays) and nohing is wrong. have the runflats on the 07 e70. has anyone else had false alerts like this? the alert still wont go away

Try reset TPM in iDrive setting menu, and when it is resetting, let your car run a short distance. Good luck.

Light went on for my wife's 07 328 (w/ RFTs) two weeks ago. While the tech noted that the sensors are rather sensitive, he said it was odd that the message light was triggered by only a difference of about 3 psi in one tire. He reset it, and sent her on her way. Nothing conclusive as to the cause, and it has not happened since (knock on wood).

I had a somewhat similar experience with my TPM last week and rear tires "looked" ok. After a more careful check using a tire pressure gauge though, I found rear passenger side was low by 5 pounds and spotted a nail in the tread. I drove to nearby gas station and had tire plugged and now all is well. I did go through the TPM reset process to get everything back to normal. So I would guess the trick for you is to reset your TPM via the iDrive settings for Tires/Vehicle.

Was that a run-flat tire that you had plugged? I didn't think you could do that.

Worked for me! My sense is that some punctures can be patched using a plug; others not. Given the expected dealer attitude though, I just went to a service station and had them repair it. Further I did not call it out as a run flat tire. I guess this is an experiment in the making, but a week later and with some high speed driving as well, everything seems fine.
If somebody KNOWS differently and that I have done a BAD thing, I'd welcome a more informed view.....

this is just one reason it would be better if it showed the actual pressure in each tire... like most vehicles that have this system.... stupid that bmw designed it this way.
