Default Cine stie e tare!!!!!-BMW E39 525d 2003 Problema mare
Am un e39 525d 2003, are cineva idee de ce nu imi trage masina in turatii joase si consuma foarte mult in oras(19%) chiar daca am facut o rescriere de soft la reprezentanta bmw(163CP) dupa ce in urma cu 2 ani am facut o remapare.la diagnoza(la reprezentanta) nu am avut nici o eroare.
in oras am consum de 19% real,dar pe calc masinii am 12% si in afara am 8%si pe calc masini am 6%.
Astept pareri.

Da' o citire a valorilor reale,un log de 2 bani n-au scos? De acolo se vede functionarea senzorilor (valorile inregistrate)de tot felul.Pentru un caz similar cu consum urban mare aveam defect de debitmetru,insa o diagnoza serioasa (cautare de erori o face orice bebe de gradinita cu o scula de 2 bani) este absolut necesara pentru a nu schimba piese pe ghicite.

daca exista diferenta re de consum intre calculator bord si pompa inseamna ca ai injectoarele decalibrate ( presupun ca ai CR)

Injectoarele CR nu se calibreaza,sau mai exact se calibreaza cu altele.Inainte de a demonta jumatate motorul de diversi "specialisti" ,trebuie citita cantitatea injectata pe logul de care spuneam mai sus,cantitatea de aer aspirata si diversele temperaturi.Din toate astea se poate trage o concluzie.Orice alta interventie facuta inainte de "radiografia" asta se va solda cu smiorcaieli de genul : am dat "jde" milioane si tot nu merge motorul,ba chiar merge mai prost.

din log se citeste cantiatea teoretica.... nu se poate masura cantitate reala... si de aia lui ii consuma mai multe in realitate decat afiseaza pe bord....
