III. Critical Technician Notes (MUST-DO)

1. Injector Calibration: After installation, ensure proper injector coding using VW VAG diagnostic tools (VCDS / ODIS) if applicable.
2. Sealing Components: Always replace copper washers and O-rings.
3. Injector Bolts: Clamp bolts are single-use stretch bolts — replace with each installation.
4. Clean Installation: Maintain absolute cleanliness — PD injectors are highly sensitive to contamination.
5. System Verification: Perform engine test, pilot injection check, and leak-back verification to ensure optimal performance and reliability.
