w203 pressure of the railpunp to high

[JFR-Tuning]

Hi,

i have a problem with a DB W203 C220D Bj. 12/2004 HP 110 new version.

The pressure of the railpunp is to high 446 kg/p by 810U/min and the injection volume is to slow 5,2 g ( normal is 9-14 g)

We change the railsensor and the pressure regulator
Also we change the quantitative controller.

Also 2 injektors.

Dose somenone know what is here the metter?

Thnaks fore your help

3) check DTCs and report here.

Hi
I think you must change presure regulator on common rail.

THE ONLY COMPONENT THAT CAN CAUSE THE FAULT AFER YOU CHANGED PE FUEL PRESSURE SENZOR AN REGULATOR VALVE FROM THE RAIL IS ONLY THE FUEL PUMP (IT SI POSSIBLE THAT THE FLOW OF FUEL ON THE RETURN HOSE FROM THE HIGH PRESSURE PUMP IS TO HIGH)
