Run Flat Indicator Active ???

hi everyone I got a bit of an issue and have no idea where to start ....

car has been driving great no issues, drove it a couple of days ago and parked it hasn't moved since. drove it today and about 5-10 minutes into trip car starts pulling to the right I pull over take a quick look around and everything seems fine, didn't hit or drive over anything. Figured id check tire pressure just in case but I can't get to the readings, the run flat indicator active screen shows. I click the pressure ok the screen proceeds to next screen indicator restarted but after a few seconds reverts back to indicator active.
I get to a gas station and check tire pressure with a gauge and the pressures seem fine. no engine / waring lights on dash.

braking is unaffected, don't have run flats, no recent mods or changes, last mod was new steering wheel a couple of months back, recently serviced in February, no known issues with car.

any help appreciate thanks.

Your vehicle has passive TPMS (tire pressure monitoring system) without the TPMS sensors, meaning it senses changes of tire revolutions on each wheel to determine if there is a pressure loss then it alerts you, it doesn't have individual readings.

For that reason, you might need to check your own tire pressure yourself using your gauge, the tire pressures to be used are cold tire pressures located on a sticker in the fuel door.

As mentioned earlier, Active means system is working properly, you may exit that menu.

oh so you're saying its just default screen, no issues and is unrelated to the car pulling to one side..

You should try that when the car is running. In the mode that you are in, it may not be reading the tire pressure.
