III. Critical Technician Notes (MUST-DO)

1. Injector Calibration: After nozzle replacement or service, re-enter the injector IMA/ISA code into the ECU using VCDS, ODIS, or manufacturer-specific diagnostic tools.
2. Sealing Components: Always replace copper washers and O-rings to ensure proper sealing.
3. Injector Bolts: Clamp bolts are single-use stretch bolts — replace with every installation.
4. Clean Installation: Maintain absolute cleanliness — contamination can cause premature injector failure.
5. System Verification: Perform pilot injection calibration, leak-back test, and engine performance checks after installation to ensure optimal operation.
