- "step": 1,
- "title": "Release Fuel Pressure & Remove Charge Pipes",
- "instruction": "Depressurize high-pressure fuel circuit. Disconnect intercooler charge piping and intake runners to access the high-pressure fuel rail."
- },
- {
- "step": 2,
- "title": "Remove High Pressure Rail Assembly",
- "instruction": "Disconnect electrical wiring harness clips. Undo rail mounting bolts (21 N·m) and withdraw fuel rail with injectors from the cylinder head."
- },
- {
- "step": 3,
- "title": "Replace Teflon Chamber Seals & Viton O-Rings",
- "instruction": "Remove old Teflon seal using plastic pick. Stretch new Teflon ring over guide cone and compress into groove. Install new viton rail O-rings."
- },
- {
- "step": 4,
- "title": "Reinstall Rail & Torque Fasteners",
- "instruction": "Lubricate upper O-rings with clean engine oil. Insert injectors squarely into cylinder head bores. Torque fuel rail bolts to 21 N·m and fuel line to 30 N·m."

Codici Guasto (DTC) e Protocolli Diagnostici
Codici guasto diagnostici (DTC) comuni generati quando questo iniettore common rail presenta usura, problemi ai circuiti o scostamenti:
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.
