suis d'accord avec SHELBY37
A2 et A6 sont les deux "sockets" sur lequel il convient de te bracher dans l'ECU
donc en résumé pour ce qui me semble avoir un possible rapport avec la conso

A2 511 231 <<<<< 511 = long term fuel mix too rich @ idle
231 = Long term fuel mixture too lean or rich in part load stage
Maintenant s'agit de passer du code erreur a la source de la panne ...
Je mise (mais je suis pas mecano) soit un pb de debitmetre d'air (la sonde qui se trouve dans l'admission air, apres le filtre air) soit un pb de sonde lambda (a la sortie echappement avnt pot catal)
