III. Critical Technician Notes (MUST-DO)

1. Injector Coding: After replacement, perform IMA/ISA coding using OEM or BOSCH diagnostic tools.
2. Sealing Components: Always install new copper washers and O-rings; old seals may cause compression leaks.
3. Injector Bolts: Replace all stretch bolts; torque-angle method required.
4. Clean Installation: Maintain absolute cleanliness; MultiJet injectors are sensitive to contamination.
5. System Verification: Conduct leak-back test, pilot injection calibration, rail pressure stability, and injector balance check.
6. Fuel System Notes: Replace fuel filter and check for water contamination; MultiJet systems are highly sensitive.
7. Seat Reconditioning: Clean injector seat of carbon deposits if present to prevent blow-by and misfire.
