Recommended Posts

salve, avrei una fiat con i relativi errori che non riesco a eliminare, l'auto in questione ha l'impianto a gpl e l'errore appare solo quando si fa il cambio da benzina a gpl..

gli errori in questione sono p0420 e p1420..

qualcuno è mai capitato o riuscirebbe a eliminare i dtc?

allego file ori e mod
