A5 2.7L TDI 2008 > Voyant prechauf TDB + Perte de puissance

[AlexLeToucan]

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:
