- "step": 1,
- "title": "Depressurize High Pressure Fuel Circuit",
- "instruction": "Disconnect low pressure electric fuel pump controller or pull fuse. Run engine until it stalls to vent high pressure fuel rail."
- },
- {
- "step": 2,
- "title": "Remove Charge Air Ducting & Fuel Rail Retainers",
- "instruction": "Unbolt hot-V intake charge pipe components. Disconnect electrical harnesses and remove fuel rail retaining bolts (10 N·m)."
- },
- {
- "step": 3,
- "title": "Extract Injectors & Renew Teflon Chamber Seals",
- "instruction": "Use puller tool T10133 to extract injectors from cylinder head. Fit new Teflon combustion seal and backing washer with assembly cone."
- },
- {
- "step": 4,
- "title": "Reinstall Rail & Torque Connections to Spec",
- "instruction": "Seat injectors into head. Torque rail bolts evenly to 10 N·m. Tighten high pressure lines to 25 N·m. Cycle ignition and verify zero fuel weepage."

Codes de Defaut (DTC) & Protocoles de Diagnostic
Codes de defaut diagnostiques (DTC) courants déclenchés lorsque cet injecteur common rail subit une usure, des pannes de circuit ou une dérive d'étalonnage:
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.
