Hello. At our Swift the mother-in-law (Swift NZ Ez.02/2017, 1.2L Automatik) the warning light for the tyre pressure was approached. It came independently of a tyre change (summer, winter, spare wheel) or similar. We have corrected the air pressure, but it only slightly deviates, we have now filled all four tyres with 2.3 bar, but the message does not go away. Since I would like to understand the problem, I would also like to read in and also a simple diagnostic device for such sensors I also have a simple OBD-2 dongle for a smartphone app, you could do it there, and with which program read out what? Thank you very much.
