Good morning in the round, I currently have a little woe with my new car and thought, I ask here, if someone knows so much and can help me. I drive the Hyundai i30N performance for about 3 weeks now. 1.5 weeks ago I had the winter tires put on it. I got the car only with summer tires and since I thought I was clever, I used the winter tires from the old car (Kia cee’d GT track) (Felgen are approved, tire size can do it, all so far ok). Now to my problem: Since I have the winter tires on it, the pressure indicator does not work. At first, nothing, but the cockpit said “Display only while driving”. As far as so good, a little longer driven for learning and zack: I get an error message from the TPMS/RDKS. The lamp flashes (after 1-2 minutes no blinking but continuous lights) and the cockpit shows at the point where I should see the pressures „TPMS(Trying pressure control system) on. the workshop I was already 2 times to the test, they probably find nothing, have put everything back again and told me that the sensors would be generally intact. Air pressure on the tires are of course also checked and ok. When starting the car the error comes directly again. They now no longer know what it is and would next exchange the sensors, if nevertheless broken (all 4?). Now my question in the round: Does one know what this is about with the error message now? Me Is it possible that the sensors that worked with the Kia are not compatible with Hyundai? At the Kia I did not get any pressures as a numerical value, but only an indication of the tyre in question if it was not true. Maybe the sensors are not suitable for the Hyundai and the direct display? Or is there a much simpler solution? I am rather a layman with cars and I want the Ä rger save, for 300€+ all sensors to change and then sit back in the car with the same error… Sorry for the long text for a relatively “small” topic, I hope there is all the information you need. A big thank you to everyone here!! LG ck-13
