I wanted to report this problem I had with a garage on a Nissan Qashqai, having to supply 4 winter tyres with their rims he also bought 4 original valves, according to what the dealership told him, and to what was written in the TPMS information (with the old update) he had to circulate for 20 minutes , incorrect procedure, from the dashboard there are adaptation menus but they do not work, after diagnosing the TPMS he found valve error so he decided to try the valve learning function from the FLEX, once the function is launched it is necessary to excite the valves in the sequence given by the instrument, once this is done everything is OK. Now in the new TPMS update there is an entry to use sensor code, which will lead workshops to use diagnostics for coding.
