My Rear TPMS was playing up on my C650GT ( 2014) After looking for a while on Youtube, how to change the Battery only and get it working again?? Watched many times. As I needed a new R-Tyre; I decided to give it a go...I took my time and installed the Battery . Tyre back on and I took it for a 25 Km run. Didn't work but somewhere ( I think it was in this Forum) I is was reading to give it time after Battery - replacement in the TPMS. 2 days later > Today I was going on the HWY for an hour and what a surprise, when I got home ...It's working !!!! Time will tell. Thanks to everyone; Norman
