I have a 2008 S with 57K mi. Has anyone ever had their TPMS continually go inactive for no reason? It started about a week ago. I checked all the tire pressures (all good) reset the TPMS and it went away for about 4 days, then I was driving and it pops on again. Re-check the tires again reset and it comes back 2 days later. Then wouldn't reset, I shut off the car for 30 min and I go out and start it, light is out. Now its happening almost every day. Do I have a bad sensor some were?

Thank you all for your help

 

I'm having the same issue, just had new wheels and tires installed. After resetting the Inactive reappears?

 

 

Well the used rims I bought must have multiple bad sensors because the TPMS wont reset at all. I bought them for snow tires next year anyway. I've come t the conclusion I have at least one bad sensor.

 

It is my understanding the batteries in the TPMS wheel units go bad after about 5 years. There is no way to tell how long the sensors sat on a shelf before installed on your rim and you will be shocked to know.... the batteries are NOT replaceable. I hope that helps in some small way.

I changed the sensor that was bad but still i'm unable to reset it, it just shows INACTIVE , i had the tire shop check all the sensors and 1 was bad, they replace it, now they did test them with their computer but still im unable to reset the TPMS alert. any suggestions?

 

Hi have you solved the problem of the message Inactive. I have same since i've changed the 4 wheels.
Thank you.

 

Hi did you ever get your wheels working? I am having the same problem on my 09 S, works and goes inactive, seems to be getting worse, I was able to reset everyday, but now some times it won't even reset I have replaced all 4 sensors with no luck. I have a bmw scan tool and the only code coming up os for the RDC module. I am hesitant to invest in a new module.
