TPMS Malfunction
I have an intermittent TPMS malfunction. I get the amber tire icon and no tire pressure indication from any of the wheels. It fails, then comes back up after an hour or so, then fails again.
My SA said this could be caused by the failure of a single TPMS transmitter in one wheel, say a failing battery...can anyone confirm this? Or would it be a failing component in the vehicle? I wanted to be a little more educated about the system before I see my SA again so I can ask him to try something more effective than just pairing the sensors again. I would think the next step would be to replace each tire pressure sensor. |

Thanks for reviving my post, I thought this was long dead. The TPMS was a problem on and off through 2019, up until I stopped driving it for the winter. I started driving the car again in April after the snow melted. The TPMS malfunction hasn't happened at all this year. I never got to the point where I took it in to get fixed.
In discussions with the SA, though, I think the next step is to replace the sensors in each tire. He was pretty sure that the failure of a single sensor would cause the TPMS malfunction where none of the pressures are displayed. I think the sensors are battery powered, and they're normally switched out when you get new tires. You may have a sensor with a low battery. I'm still on my original tires. |

It is usually one or more failing TPMS batteries. Usually the BMW dealer or Tire retailer has a scanner that can tell exactly which one is no longer sending a signal. This shouldn't be rocket science. Cars have had these systems for over 20 years now.
Note the typical lifespan of a TPMS sensor is from 7 to 9 years. If I am anywhere around 6 or more years, and needing a tire change, I replace them. It makes no sense to wait until they fail and pay just to have tire removed to replace them and then remount and balance the wheel. I lot of unnecessary labor charges that way. But note that like anything, the batteries (or the electronics) can fail prematurely. Not unheard of to have a failure at less than 4 years. |
