Valeurs capteurs MAF

MrFox24 · 29 mars 2025

Bonjour à tous !

Aujourd'hui, petite question technique concernant le capteur MAF sur l'A4 B9 3.0 TDI 272 ch.

Connaissez-vous les valeurs minimales et maximales du débitmètre lors de la plage d'utilisation du moteur ?

Pour ceux qui ne connaissent pas mon problème, sur mon A4 B9 Stage 2, le voyant moteur (code P0101) revient continuellement.

Capteur changé, filtre à air changé, pas de rupture sur les câbles du débitmètre.

Mon objectif serait de vérifier ces valeurs et de savoir si elles dépassent les maximales constructeur et éventuellement de modifier ces valeurs pour rentrer dans la norme et éviter que ce voyant moteur revienne.

Bonne journée à vous tous ! Au plaisir de vous lire !

Ton défaut est signe que le signal donné par le débitmètre n'est pas dans la normae de ton calculateur avec un rapport AFR optimisé entre 14 et 20/1 C'est à dire un rapport de X grammes d'air pour X gramme de carburant, dans le rapport en question entre 14/20 grammes d'air pour un gramme de carburant. Dans le cadre de ton stage, ta cartographie a t'elle été bien faite ? As tu changé pour un autre filtre à air entre temps ?

As tu regardé si tes durites d'air étaient correctement connectées ? Si oui, il faudrait monitorer l'entrée d'air détecté par le débitmètre ? Quel genre de filtre à air as tu ? Normal ? Sport ?

La cartographie à été bien effectué, jai confiance en mon mappeur meme si je n'exclue pas un erreur qui peut arriver a tout le monde !

Avant le stage jai installé un filtre a air sport de la marque BMC.

Lors de l'apparition du défaut la voiture n'avait pas encore la reprogramation.

Afin de vérifier jai remis le filtre a air d'origine suite à la reprogramation ce qui m'a value de raté de combustion quand la voiture était "en roue libre ou a faible allure en ville".

Cependant le défaut P0101 ne revenais pas...

Si tu as VCDS, peux tu poster un autoscan de ton véhicule ?

si on résume, tu as un défaut et tu reprog quand même ?

MrFox24 · 11 avril 2025

Il y a 5 heures, s4_ludovic a dit :

si on résume, tu as un défaut et tu reprog quand même ?

Pas vraiment, quand jai eu le defaut et que j'ai vu que c'était un problème de debimetre jai changer le débitmètre, entre temps jai fait la reprog et le defaut est réapparu, comme je disait il apparaît des fois comme ca après une accélération en phase de décélération...

Je peux rouler des fois 1000 km sans qu'il ne revienne et des fois tout les 20 min il revient...

Et je pensais également que la modification des valeurs avec la reprogramation allait éviter qu'il ne revienne !
