Defected wheel on board

Hello dear forum, this morning I got into my thickness to drive to work. When the engine started, the following message immediately arrived in the display: “RDKS – defective wheel on board” A look at the infotainment showed me all 5 tyres (incl. spare wheel) with yellow exclamation mark. I first deactivated the tyre pressure control and later switched on again, the error persists. Visual inspection showed no damage or flat tires. Then I am to the tankste I drove and checked the pressures on all the tires –> are OK. Now my questions (before I drive) : – It was relatively cool this morning compared to the last days, the car showed me 7°C. Could it be that the sensors were too cold and first have to warm up a little over the day? – Or are the sensors actually defective? Until yesterday they still worked perfectly, moreover, I am surprised that then directly all tires cause problems. Did you already have m al this problem? Have you had experience with it? Wouldn’t want to thank you for your efforts now already in advance Greeting Krischan483
