Pourquoi mon turbo monte trop en pression?

Discussion dans '1.9L (4 cylindres)' créé par laurenzo44, 24 Avril 2013.

  1. Bonjour suite à de nombreux problèmes de coupure ( mise en mode degradé )
    je précise que je n'ai plus d' EGR, elle est remplacé par deux plaque et bouché la durite

    J'ai :

    - démonté et entièrement nettoyé le turbo ( il était grippé )
    - changé ma N75
    - changé toutes mes durites de dépression
    - changé ma G71

    j' ai toujours des coupure du à une trop forte pression du turbo

    Voici un log ou il n y a pas eu de coupure mais on voie la N75 a plus de 94% .....

    Re : Pourquoi mon turbo monte trop en pression !!!!!!

    Bonjour

    Le dépannage donne (en plus de vérifier les durites, la GV du turbo, la N75,la waste gate , la présence effective de dépression dans les lignes de régulations turbo) remplacement du capteur G31 charge pressure sensor for turbo boost ( transmetteur de pression de débit turbo )?????

    Re : Pourquoi mon turbo monte trop en pression !!!!!!

    un cata bouché occasionne une perte de puissance.
    pour en avoir le coeur net,tu peux essayer de laisser un petit jour entre turbo et echappement mais minime ,l'épaisseur d'une rondelle par exemple et tu fais un essai routier.
     
  15. Re : Pourquoi mon turbo monte trop en pression !!!!!!

    Les coupures sont arriver apres 240 000km, turbo grippé.

    J ai démonté nettoyé et tout à rouler super bien jusqu a 248 000km et re-coupure
    donc redémontage et re-turbo gripper ...
    la j'ai tout néttoyé, tout changer, N75, durite depression, .... et rien ni fait le turbo est en surpression.

    C est quoi le mastervac???
    C est quel capteur le G31 ??


    merci les gars

    Je sait qu on peut vider un cata en cassant tout dedans, est ce utile??

    Peut on le Nettoyer ??? ( Karcher, air comprimer, feu ..)

    la G71 et non la G31 est intégrée au calculateur sur ton modele?peu etre ton probleme vient de cette durite a l'interieur de calculateur sois coupé ou repmli d'huile.

    Re : Pourquoi mon turbo monte trop en pression !!!!!!

    bonsoir laurenzo44 ta montée en pression est due a ton turbo qui grippe (la gv) a 240 000 ton turbo a bien vécu et la gv doit étre bien usée ce qui provoque des points dures et du coup ca grippe (comme tu dis néttoyage remontage et regrippage ).....c est ton turbo qui est hs....change le et ca ira mieux..........

    vider un cata sur un mazout ca sert pas a grand chose .....
    pour le néttoyer au karcher dans le sens inverse du flux des gaz d échappement
     
  20. Re : Pourquoi mon turbo monte trop en pression !!!!!!

    Slt Tof, je comprend que 250000km c est deja pas mal mais je t assure que le turbo est nickel, les aubes de la GV bougeais juste avec les poiles de la brosse a dans tellement c etait parfait.

    Je vais voir les durites ...
    ?,
    Est ce normal qu apres avoir demarer au bout de 5 secondes, au ralentie, j entende un sifflement (le turbo qui s enclanche ) et je l entend super bien a l arriere au niveau de la sortie d echappement
