III. Critical Technician Notes (MUST-DO)
1. Clean Installation: Clean the nozzle thoroughly (ultrasonic cleaning recommended) before fitting.
2. Sealing Components: Always replace copper washers, O-rings, and seals.
3. Injector Mounting: Follow OEM torque and alignment specifications.
4. Post‑Installation Testing: Perform leak-back and test-bench spray checks to verify correct spray pattern and absence of leaks.
5. Calibration / Coding: Use VW / Audi / Seat diagnostic tools for injector coding if required.
6. Fuel Quality Notes: Use clean, high-quality diesel; replace filters during injector service.
7. Storage & Handling: Store nozzles in a clean, dry environment; avoid mechanical damage.
8. Performance Monitoring: Observe injector performance after replacement (idle smoothness, power, smoke, fuel return flow) to catch early issues.
9. Common Fault Symptoms: Rough idle, hard cold start, reduced power, black smoke, or excessive fuel return flow.
