Range comparison

The following table lists turbos compatible with specific Volkswagen TDI motorizations, covering a range of power outputs and engine codes. Each entry is designed to meet the exacting standards of TDI engines.

How to choose

Selecting the right turbo requires attention to motorization, power output, and engine code. Compatibility is paramount, as mismatches can lead to inefficiency or failure. Consider the turbo’s condition and remanufacturing standards to ensure longevity.

1. Verify the engine code and power output to ensure the turbo matches your vehicle’s motorization exactly, avoiding costly errors.
2. Check for variable geometry turbos if your TDI engine requires precise airflow control for optimal performance.
3. Opt for turbos with a core deposit option to simplify the return of used parts, streamlining the exchange process.
4. Prioritize turbos from remanufacturers with a proven track record in TDI engines to deliver reliability.
5. Assess the turbo’s packaging for bulk or individual use, depending on your procurement needs and storage capacity.
6. Confirm the turbo’s compatibility with your vehicle’s exhaust and intake systems to prevent installation issues.
7. Evaluate the turbo’s condition, including the CHRA and cartridge, to ensure it meets your performance expectations.

Storage & logistics

Bulk turbos should be stored in a dry, temperature-controlled environment to prevent moisture damage or corrosion. For garages, palletized units allow efficient handling and rotation, ensuring older stock is used first. Individual cartons should be kept upright to avoid stress on seals and bearings. Regular inventory checks help maintain stock quality and prevent obsolescence, especially for less common TDI variants.
