III. Critical Technician Notes (MUST-DO)

1. C2I / IMA Coding: After installation, enter the Injector Compensation Code (C2I/IMA) into the ECU using Renault CLIP or compatible diagnostic tools.
2. Sealing Components: Always replace the copper sealing washer and combustion seal — reusing old seals may cause leaks.
3. Injector Bolts: Use new stretch-type clamp bolts each time injectors are removed.
4. Clean Installation: Maintain absolute cleanliness — Piezo injectors are sensitive to contamination.
5. System Verification: Perform leak-back test and pilot injection calibration after installation to ensure balanced operation and proper engine performance.
