buna ziua

sant poesorul unui volvo s 60 d5 din 2004.nu am avut probleme cu el pana acuma si am 245000 km(il am de cand avea 88000)

de putin timp am inceput sa am o problema legata de alimentarea cu motorina.prima data sa oprit motorul cand compiuterul de bord imi arata ca mai am motorina pt inca 80 km,dupa aceea sa intamplat cand indica ca mai am autonomie pt 250 km.ultima oara (acum cateva zile)pe cand eram pe autostrada in italia sa oprit motorul si imi indica ca mai am motorina pt 450 km,norocul meu a fost ca aveam un peco la nici 200metri si am reusit sa ajung sa alimentez (am facut plinul si au intrat doar 52 litri-deci motorina aveam in rezervor)

daca cineva sa mai intalnit cu o problema asemanatoare si ma poate ajuta

va multumesc anticipat

Probabil pompa de echilibrare a rezervoarelor nu mai functioneaza, sau senzorul de nivel... Rezervorul e impartit in doua, si cand se goleste dintr-o parte, o pompa completeaza din cealalta "jumatate" pana echilibreaza nivelul.

multumesc pentru raspuns.

sti cumva daca este o operatie grea schimbarea pompei de echilibrare arezervoarelor?si un pret estimativ a piesei?

Mda, m-am exprimat eu gresit, nu exista pompa de echilibrare, scuzele mele... Rezervorul are DOI senzori de nivel, Mai departe scrie aici si de ce (din VIDA):

The engine control module (ECM) sends a request to the central electronic module to start the pump.

Fuel is transferred using the ejector principle from the left-hand fuel pocket to the right-hand pocket depending on the amount of fuel in the right-hand gallery.

The fuel level sensor in the right-hand fuel gallery transmits data to the rear electrical module about the amount of fuel. The rear electrical module transmits a CAN signal on the network which is retrieved by the central electronic module

The central electronic module activates the fuel pump (FP) relay when the level in the right-hand gallery falls below 13 liters and deactivates the relay at 21 liters. If the signal for the amount of fuel is missing, the central electronic module activates the fuel pump (FP) to guarantee the fuel level

There are two valves integrated in the fuel pump (FP). There is a check valve, whose task is to prevent the low-pressure fuel pump (FP) from drawing fuel through the electrical fuel pump (FP). There is also a pressure limiting valve in the fuel pump (FP) which limits the pressure to approximately 300 kPa absolute pressure in the supply line to the filter
