Good day, have been driving an i20 Bauj. 2022 for 8 weeks. I have heard now that the battery is changed by the SOS system after 3 years during the inspection. Cost only for the change 170 Euro. Is it really necessary to change it so early, or lasts longer. And is it TÜV relevant if the system no longer works. Because I assume that the SOS control lamp then goes on.
