Dopasowana pompa wysokiego ciśnienia (Układ paliwowy)
Pracuje w tym samym układzie Common Rail wysokiego ciśnienia. Przy spadku ciśnienia (P0087) sprawdź wydatek pompy przed wymianą wtryskiwaczy.

Kody Bledow (DTC) i Protokoly Diagnostyczne
Typowe diagnostyczne kody usterek (DTC) wyzwalane w przypadku zuzycia, awarii obwodu lub rozkalibrowania tego wtryskiwacza common rail:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
