i think all will be resolved , I solved some similar cases here... if you have any problem just reply i can send you the number(whatsup) of support team and they will resolve any kind of... about MES you can order yours.. i can send you a cheap link for the dongle and a yellow cable with the new chip for fiat that for me works perfect.In the meantime, thanks.
I ordered the Hiworld canbus that you suggested Canbus Hiworld and I looked at the thread where you explain perfectly.
I'll try to see if I can solve it this way and at worst I'll look for someone with MES and a yellow cable (or I'll buy this too but I have doubts because my laptop has Windows 11 and I don't know if MES is compatible).
If I can solve it you have won a good bottle of Italian wine from my area (I prefer spending on friendship than throwing money at the fiat assistance center for a proxy alignment).
I have enjoyed the wine of your country for several years when I studied at Tor Vergata and my connection with Italy is old and familiar too.
Italy is beautiful not only for the taste of the wine but for everything it represents, my father used to say.. if you drive a Fiat 500 without listening inside, Albano, Toto or Adriano is nonsense
