Scania 530cv no torque in the lower

[domenic68]

I have a problem on this scania 530cv year 96 has a pair in the bottom opens to 1800giri

check if the turbine pushes and the state of the intercooler

[munro]

I would first check the filters..
then check the power supply line of the fuel from the tank to the pump and that there are no "aspirations of the air"...
if everything ? ok in that sense controls the pressure of the fuel inside the pump...
many times the return valve diesel stara leaving to drain fuel pressure and...
then the pump remains "really thin" diesel...
if even after these controls, the defect remains you have to look at LDA on the pump and check the pressure turbo...

do not forget that if after all these checks the defect remains...the only thing left to check are the fuel injectors....
maybe they are off by as much damage and less diesel fuel needed...

first check the membrane lda off the tube sullapompa and with a fitting and a piece of pipe put type "vacuum"
if it was broken this the feeling of driving a truck aspirated

replace the sensor of the turbo on the manifold, and you'll see that the vehicle system, the 144 530 has a pump in the line controlled by a control unit with regard to advances, position rod rack-and-pressure turbo
trusted replace the sensor and it will go? as before

And the fumosit? I guess it's nothing now?

[igor]

I changed the right one this evening on a R500 with the same problems and with the sensor ? everything went well
this ? one of the defects of scania, has the pressure sensors and the temperature is very delicate

but the diagnosis is not from nothing igor?
