III. Critical Technician Notes (MUST-DO)

1. Injector Coding: After installation or nozzle replacement, recode injector correction values (IMA / ISA code) into the ECU using STAR Diagnosis or compatible Mercedes diagnostic tools.
2. Sealing Components: Always replace copper sealing washers and O-rings with new parts—reusing old seals can cause compression leaks and injector blow-by.
3. Injector Bolts: These are single-use stretch bolts; always replace upon removal.
4. Clean Assembly: Common Rail systems require absolute cleanliness. Even microscopic contamination can lead to nozzle failure or poor spray pattern.
5. Calibration & Leak Test: After installation, perform leak-back and pilot injection calibration tests to ensure injector balance and system performance.
