    20100521_GTX_0003.JPGWe all love this mythical and popular car, because we sailed in one being childrens, because someone in the family had one or just because it always made us want it... because it's endearing, whatever we say.
    Its great success is certainly due to the fact that with a simple mechanics, with little or no electronics, it is easy to maintain by yourself without expensive tools, without forgetting that the parts are not expensive and always easy to find. Even today, for some homes, students and people with "little budget", it is a source of great comfort at a lower price: far from car loans and garage mechanics, which are becoming more and more inaccessible. The small engines models (the most common) are very robust and still consume very little, sometimes less than recent "equivalent" cars, which makes it by definition just as ecological, if not even more by the simple fact that we we always use it instead of buying new ones ... At the level of the official technical control, benefiting from its "seniority", it does not undergo the modern standards much too restrictive, the tranquility is assured.
    Today it is still an interesting car for everyday use, especially and clearly from an economic point of view.
    Collectors are also beginning to take an interest in this 30-year-old "granny": restoration, maintenance or refurbishment, repairs, etc ... make it possible to find "newer than new" models for the pleasure of the eyes and to see this French heritage thus safeguarded.
    We have created this community to bring together all those who are interested and who wish to take part in this adventure to preserve their Renault Super 5, whether by maintenance, repair or restoration: you will find here all useful information and tips on these topics.

    The forum is freely accessible in its entirety: there is no need to contribute, buy, neither pay anything to integrate the community and participate.
    To be able to ask questions and share your interest, all you have to do is register and present yourself properly!
    You do not have to have a Super 5: an interest in auto mechanics is enough

Bonjour,
Je fais suite à un topic clos concernant la XR25 : https://www.forum-super5.fr/index.php?/topic/18990-valise-de-diagnostic-xr25/#comment-735106


Un problème sur ma clio 1 ph 2 moteur D7F ECU magneti marelli 06R qu'aucun garagiste, ni même renault, n'a su résoudre aujourd'hui (2025) me fait prendre le taureau par les cornes et me fait découvrir le monde passionnant du diagnostique.


Je voudrais diagnostiquer moi même ma clio et identifier ce qui est à l'origine du problème de calcul d'injection.


Le ralenti monte jusqu'à 3000 tours, à l'arrêt, et de manière aléatoire : un jour oui un jour non... lorsque je roule, et lorsque c'est un jour avec le problème, le moteur est "aggressif", passant d'un coup de l'acceleration au frein moteur, c'est très désagréable. De plus, elle ne passe plus le CT car mélange trop riche et donc trop de pollution.

 

Mes lectures et recherche m'ont amené à conclure que c'est possible à moindre frais avec XR25PC et un peu d'électronique, sans investir dans un système pro.

Je me suis fabriqué le cable et j'ai installé XR25PC tel que Aganyte l'a décrit.

 

Bon, pour l'instant ça ne fonctionne pas, mais je voudrais faire appel aux spécialistes pour m'assurer d'une chose :
Savez-vous si XR25PC fonctionne avec le magneti marelli 06R? Je ne suis pas sûr qu'il utilise le protocole Fenix..


Quand je branche un multimètre entre la pin 9 du connecteur 11 broches pré OBD et la masse (2) je devrait voir des bits passer non ? ou bien un code hex doit réveiller le ECU ? Car je ne vois aucun signaux genre TTL passer du tout... donc pas étonnant que XR25PC ne voit rien.

 

Merci de votre aide !
