I believe the TPMS should reset itself after covering a few miles IF you adjust the pressures OR disconnect the 12 volt battery.
I know this because I removed my 12 Volt battery from my Trophy ? to do a job, about 2 weeks ago.
It was completely cod the car for about 15 minutes.
When I reinstalled the battery, there was NO tyre pressure readings being show on the App or the dash panel.
Just two dotted lines where the tyre pressures would be displayed.
It was the same inside the car, on the display.
But after driving the following day for about 5 - 10 miles the TPMS had relearnt the settings and all was well !.
There is a single TPMS sensor on the back of the tyre valve INSIDE each wheel, these have a coin cell battery inside each on the sensors.
They “Ping” a signal to a module inside the car.
If you have manually confirmed that each wheel has the same reading and you are still getting an incorrect warning, it could be just a glitch.
If so, you could try the old disconnect the negative lead on the 12 volt battery, leave for about 15 minutes, then reconnect and take the car out for a drive ( 5 - 10 ) miles.
You will have lost ALL of the readings now, but they will all return after a short drive.
If you still get a incorrect TPMS warning, then it off to the dealers I am afraid.
