My 2017 M2 gave me all kinds of TPMS fits on my first track weekend. Everything worked fine until Saturday afternoon when I got a high pressure warning, which stuck around the rest of the afternoon despite bleeding some air out before each session. I was able to reset the system on the way home. On Sunday I started at 27psi, got the low pressure warning after a couple laps and was forced into comfort mode. Not sure that made a big impact in my novice lap times! From there I was able to initiate the reset and get back into sport mode for later sessions but finally I got a TPMS malfunction warning and the system still won’t reset. I have even tried a hard reboot of iDrive. Any suggestions for just shutting the damn thing off permanently?
