Key Product Features

• 100% Brand New: Zero-mileage assembly. Every component, including the integrated exhaust manifold and pneumatic actuator with position sensor, is factory-new.
• VSR High-Speed Balancing: Precision-balanced at speeds exceeding 150,000 RPM to eliminate vibration, ensuring silent operation and maximum bearing longevity.
• Calibrated VNT System: The Variable Nozzle Turbine (VNT) mechanism is pre-set to factory specifications, ensuring seamless boost delivery and preventing "Limp Mode" or P0299 underboost errors.
• Optimized for DPF Systems: Designed to operate within the specific thermal parameters required for vehicles equipped with Diesel Particulate Filters (DPF).

Critical Installation Requirements

The 1.6 TDI engine is sensitive to oil quality and clean air intake; please follow these steps:

1. Mandatory Oil & Filter Change: Use only high-quality synthetic oil meeting VW 507.00 specifications.
2. Turbo Priming: Fill the oil inlet port with clean oil and manually rotate the compressor wheel multiple times before the first start to prevent "dry start" bearing failure.
3. Inspect EGR & DPF: Ensure the EGR system is clean and the DPF is not restricted. Excessive backpressure is a leading cause of premature turbocharger failure.
4. Air Intake Hygiene: Ensure the air filter is brand new and the intake tract is free of any debris or oil residue from the previous failure.
