On the facelift model the TPMS can be disabled in the EVIC i believe.
If you run with dodgy sensors i thinkyou get the annoying bongs. I dont know what happens if you unplug all the 3 transponders and the module. I assume you would get communication error codes logged (U codes) but i also assume there would be no warning lights.
I would be tempted to try unplugging the TPMS module and see what happens, unless the warning bongs stop of their own accord without you needing to do anything.
