    TPM fail and filling the rear tire

    Hello everyone. On my third BMW and my first BMW with Tire Pressure Monitoring.

    I have an '08 KGT, putting the bike at 4 years old and in line for a replacement of the TPM sensors due to dead batteries. I have the yellow "!" and the rear tire pressure shows intermittently.

    Question 1: The only fix is sensor replacement, correct? Any tips for tricking the unit into working again? I juuuuuuust had the rear tire replaced and asked them to look at the TPM sensor. They thought they had it working, then put the tire back on and the sensor stopped working. They want another $150 to replace it. Sigh.

    Question 2: Any tips for filling the air on the rear tire! Just stopped by my local gas station and realized there's no way to get the air hose on the raised and very rigid TPM-enabled tire nipple. Do I have to find a BMW-certified gas station with a BMW-certified tire pump? "You got me, BMW; you got me! Good one!"

    Question 3: Any way I can just disable the TPM system? Anything I can just unplug to turn the whole thing off?

    It would be great if BMW could code their firmware to hide the yellow "!" after 5 minutes of "no connectivity" with TPM. I think a constant nag is a little gratuitous; after 5 minutes of nag, I've got it.

    Thanks for reading!

    If you google battery replacement TPMS BMW motorcycles you will find the batteries can be replaced. Takes a little scraping of the exopy coating they use two small batteries that appear to be photo type cost $5
    Sure worth the try
    Angled double chuck to fill tires works best

    In recent weeks I have posted the link to the advrider thread as to how to replace the battery.
    I have posted it here, perhaps more than once, in bmwsporttouringforum, in bmwlt forum, at bmwf800ridersforum and probably other places.
    Just open the thing up and replace the battery.
    Use some 3 M sticky stuff to close it back up. Save $300.
    Ain't it worth a try???

    They should be able to test it without removing the tire with a proximity-type device to see if it's responding.

    When it quits for good the front sensor will stop responding as well.

    That $150 is only the sensor, not including labor for replacement and relearning. Might be worth the effort in replacing the battery.

    NOBODY is going to make it easy to disable a safety system. Or ignore it.

    Your BMW dealer can disable the system. It simply requires connecting your bike to his factory tester and selecting the proper option. I don't know what he will charge, however.
