Bonjour à tous! Suite à un achat récent d'une occasion A5 ...2.7L 250 000km de 2008 après 2 mois d'utilisation en roulant sans problème. Puis une fois à 130 kmh, moteur chaud = Voyant orange TDB de ' prechauffage a 2 spirales clignote et perte de puissance : une fois puis plus rien (je fais essentiellement de la ville) Puis départ en weekend : perte de puissance sur autoroute à l'aller et au retour. Et maintenant, ça revient lors de mes trajets quotidiens (10km d'autoroute à 110kmh alors que ça ne le faisait pas avant). J'ai juste fait reprogrammer le volant par Audi courant Juin J'ai regardé un peu avant de poster ... quels peuvent être les causes de panne possible ? Vanne EGR encrassée ? Sonde Lambda HS ? Bougies ? Autres causes ? Voici le résultat du passage au Vagcom: ------------------------------​------------------------------​------------------- Address 01: Engine (J623-CAMB) Labels: 059-907-401-V1.clb Part No SW: 8K1 907 401 F HW: 8K0 907 401 Component: 2.7TDI EDC17 H01 0004 Revision: --H01--- Coding: 0114002C02070928 Shop #: WSC 12228 002 1048576 ASAM Dataset: EV_ECM27TDI8K1907401F A01004 ROD: EV_ECM27TDI8K1907401D.rod VCID: 2F6AC8FE76860C3940-807A 7 Faults Found: 5171 -
