Salut,
Daca doresti poti sa oferi si cateva detalii despre masina (nu doar anul de fabricatie), motorizare sau chiar codul motor (daca il cunosti).

DF771
Literally, this code can be deciphered as “the adaptive parameters of the fuel supply control system are outside the operating range.” This suggests that the fuel system is not able to regulate the flow of fuel for the formation of the air-fuel mixture.

The main causes of the problem:

malfunction or clogging of the high-pressure fuel filter; device replacement required;
nozzle contamination or damage to their power circuits;
a malfunction in the fuel pressure sensor installed in the pump.

eu as zice ca ultimul...dar trebuie investigat...sa vedem ce documente se pot gasi/primi.

Eroarea DF771 nu se refera doar la cele citate in postul #4 (dar care pot ajuta), este una destul de “urata”, pentru un ScenicIII 1.6 dCi motor R9M402\404 eroarea DF771 =DTC0002xx =Indice de adaptare reglare debit =Circuit de reglare presiune rampa de injectie se refera la actuatorul de debit carburant, injectoare, pompa de inalta presiune, regulatorul de presiune al rampei de injectie, regulatorului de debit de carburant, senzor de presiune rampa de injectie, sonda de temperatura lichid de racire, senzor de temperatura carburant, pompa de injectie, filtrul de carburant, aer in circuitul de carburant, circuitul de carburant, etc. …
Pot detalia procedura de diagnosticare dar tinand cont de “.. si nu mai trage presiunea in rampa arata ca ar trebuii 1000 bar si dezvolta doar 100 , 200 bar..” plus ca “acest client a bagat motorina de la un prieten din niste bidoane.. motorina a fost destul de rea..” cred ca trebuie vazuta cam toata injectia atat cu testerul de diagnosticare cat si desfacut \verificat cam tot pe acolo.

Iti multumesc mult de raspuns si de ajutor.. voi desface pompa injectoare si le voi duce la verificat.. daca totusi sunt bune care sensor ar putea fii defect ? Ala dupa pompa dar chiar si ala de pe rampa?
