Information for the question round concerning valve sensors. Would be interesting to know if this technical innovation invented the same people who are also responsible for how bent a salad cucumber or a banana has to be or from which psychiatric clinic they have otherwise escaped.Otherwise, such a nonsense cannot be explained. Have a Hyundai i20 (simple equipment variant).That means without LCD display, but probably the same electronics as regards the valve sensor business. I don’t have a display where I see its position in the event of a wheel’s error, nor does a vehicle image display where the corresponding wheel is displayed.Also I can’t do any reset on the display as with the larger equipment,Mercedes,BMW,Audi etc. with LCD. Named for me and on request according to technical information from Hyundai, as soon as I set a wheel to a different position or change, I get the yellow tyre error indicator on the control light field. Since the system has programmed the values and the position of the wheels and the new positions of the wheels no longer independently recognizes to my tyre dealer or best immediately to Hyundai to reread and program the values against expensive money, since not even the reading devices at my tyre dealer have managed this.This I find a shameless intervention in the private driver life, since I now have no other possibility after a wheel change on a If the vehicle gets the badge at the time of the appointment, if the tyre control light is on here and I drive with this condition until the TÜV date? After about five years at the latest, the button cell batteries contained in the sensors gradually say goodbye, then new sensors are to be purchased again ( unit price € 70.- ) in addition to the wheel and tyre montage. Eldbeutel is already running. Greetings from an angry driver.
