Instrucțiuni de montaj
- [
- {
- "step": 1,
- "title": "Depressurize Fuel Rail & Isolate High-Pressure Circuit",
- "instruction": "Pull fuel pump relay in rear fuse box and crank engine for 10 seconds. Verify scan tool low pressure fuel reading falls under 5 bar before cracking flare nuts."
- },
- {
- "step": 2,
- "title": "Inspect Engine Oil for Fuel Dilution",
- "instruction": "Pull oil dipstick. If oil level is elevated or smells strongly of gasoline due to internal plunger seal blowby, schedule immediate oil and filter change."
- },
- {
- "step": 3,
- "title": "Clean Cylinder Head Bore & Lubricate O-Ring",
- "instruction": "Clean mounting bore on cylinder head. Coat new Viton O-ring with clean engine oil. Never use silicone sealant on flange face."
- },
- {
- "step": 4,
- "title": "Torque Flange Fasteners Alternately",
- "instruction": "Position pump on cylinder head while camshaft is at base circle. Thread mounting bolts hand-tight, then torque alternately to 12 N\u00b7m."
- },
- {
- "step": 5,
- "title": "Connect High-Pressure Hard Line & Torque",
- "instruction": "Align high-pressure hard line square into pump discharge port. Finger-tighten fitting, then secure flare nut to exactly 28 N\u00b7m."

Coduri de Eroare (DTC) si Protocoale de Diagnostic
Coduri comune de eroare de diagnosticare (DTC) declansate atunci cand acest injector common rail sufera uzura, defectiuni de circuit sau abateri:
P0087Critical
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
P0201 - P0208High
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.
P0300 / P0301+High
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
P0088High
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
