Tach, my i20 (from 2016) now has these tire pressure sensors, that’s not what I had yet. Since yesterday evening a rear tyre has lost pressure (probably because it was driven over some kind of harmless-looking stringer after the storm, was partly full of it…). So, in the evening the warning light was on, I then “filled up” at the gas station – one tyre was at 1.7 bar, while the other one was at 2, I pumped up to 2.0. A few minutes later the display went out again. This morning the light was on again, was in the afternoon with the tank, and again so 1,6.,1,7 bar. There is then probably a hole in there or whatever… Have with the vector 4 seasons mature about 10’000km down, then means probably, 2 new, what? Until I have a workshop appointment, I would have to put the spare wheel on it. (I think with my equipment a real wheel in it, no plastic bumps) Do you have to pay special attention to something because of the sensors there?
