Does anybody know if the system as fitted to the 500X requires special valves or does it work some other way? Having new tyres soon, unclear about the valves.
It works by sensors on each hub comparing the relative speeds of each wheel, so nothing on the valves. If you are having 4 new tyres it should work straight away, if just two, you may need to do a reset. There's info in the manual.
Have you gone through lots of puddles and have you tried doing a re-set?
Sunday and Monday were incredibly wet where I was, so yes, lots of puddles etc. Activated randomly Sunday, Reset, then activated randomly Monday, less than 24 hours later. Tyre pressures all OK. Reset again with less rain and no further warnings
