TPM won't reset..
I've been battling this for a couple months now on my 08 M3 with the tech package. It first started with a cold front... start the car and get the low tire warning on all four. I look at them, they are fine. I'm in Colorado, so the temperature has big swings and it goes off everytime the temperature falls. Use the TPM menu and hit reset. And it stays on "resetting TPM". Literally, I've left it parked in the driveway for a half hour and it won't reset.
When I drive, every couple minutes it pops up the warning dominating all the gauges... Sorry, but I use my clock, the nav system, digital speedometer, etc. It is extremely aggrevating and distracting. I did finally get it to reset and all was good by getting the tires within 0.1 lbs of each other and fillng them out of my nitrogen bottle... Worked until yesterday when I had the winter shoes mounted. Now it's back and refuses to reset... Is this something I should take to the dealership? Can they disable the system or at least set a minimum pressure before it triggers? |

I do not think that the TPMS reset while the car is parked. I am pretty sure that you have to hit the reset button while at a stand still and then start moving.

he is right, read the owners manual, you have to drive the car for about 5-10 miles. and yes it does take time to reset.

Agree, the direction are confusing. It says to stop the car, which you should do when you first hit the reset. But then start moving. If you just sit and wait it will never reset, have to be moving.

What I haven't tried is using the button on the dash... I've just been using the hud menu. |

Had a nail in each of the rear tires in the M6. Very slow leak and the TPMS would go off every two weeks.

Yep...
Literally the warning popped up the second I started the car after getting the winter tires put on. It just sticks on "resetting TPM" until a new warning pops up. Checked the pressure with a crappy pencil gauge and it's good at 32; I have not checked the others to see if there's a difference side to side. I've got a high quality racing gauge (one that measures in tenths) at home I'll use tonight. Hopefully it's just something like 36 on one side and 32 on the other... One of my thoughts would normally be a damaged sensor during the changeout, but this whole TPM warning fiasco started well before I swapped the tires. Another thought did cross my mind. Before any of this mess, the M3 was at the dealership for a couple days having work done. Maybe they did something to the computer? I seem to remember reading somewhere that the techs can adjust the parameters to reduce the "false positives".. maybe it got reset into very tight tolerances? btw; tried the dash button over lunch. Didn't make a difference. |

The TPMS use batteries for the wireless sensors. They don't activate until the vehicle is rolling. Try to reset it once you're actually in motion, and stay in motion driving for about 10-15 minutes.

I've got some time with Thanksgiving. Tonight I throw on my real gauge and balance those pressures out so I can rule out it being a real issue. Wonder how long those batteries last? That could a the issue, but doubt it. I'd think it'd show red versus yellow on the tire, and the past round of this, all four showed yellow and wouldn't let me clear it (pressures were fine then too). |
