Fuel injector VOLKSWAGEN Passat (B5)

This category specializes in remanufactured turbocompressors and related high-pressure components for TDI engines, addressing the core needs of mechanics, repair shops, and automotive enthusiasts. Whether you are troubleshooting a loss of boost pressure, excessive exhaust smoke, or unusual noises from the turbo area, these parts provide a cost-effective alternative to new units. The selection covers six power outputs across Volkswagen Group diesel platforms, ensuring broad applicability for both common and niche applications.

Each turbocompressor in this range undergoes a standardized remanufacturing process that includes core cleaning, component inspection, and precision reassembly using OEM-grade parts. The wholesale format is designed for professional buyers who require bulk availability without compromising on quality or traceability. By sourcing directly from European remanufacturers, we eliminate unnecessary intermediaries while maintaining strict quality controls aligned with industry standards.

Range comparison

The table below organizes the available turbocompressors by motorization, power output, and compatibility. Each entry includes the exact reference and a brief description of its intended use case to simplify selection for professionals and enthusiasts alike.

How to choose

Selecting the right turbocompressor requires evaluating several key factors beyond mere compatibility. These criteria ensure long-term reliability and performance alignment with the engine's original specifications.

1. Conditioning: Verify the remanufactured unit includes a core deposit system to simplify returns of the old part and reduce upfront costs for bulk orders.
2. Conservation: Prefer turbocompressors stored in climate-controlled environments to prevent moisture damage and ensure component integrity during transit.
3. Regularity: Choose suppliers with a consistent remanufacturing process to avoid variations in performance or premature failure after installation.
4. Rotation: Opt for units with a documented history of use in similar applications to minimize compatibility risks and maximize longevity.
5. Traceability: Ensure the part includes OEM reference numbers and motorization details for accurate identification and warranty claims.
6. Packaging: Select units shipped in protective, anti-static containers to safeguard sensitive components like variable geometry mechanisms.
7. Compatibility cross-check: Confirm the turbocharger matches the engine code and power output to avoid mismatches that could damage the system.

Storage & logistics

For professional buyers, proper storage of remanufactured turbocompressors is critical to maintaining their condition until installation. These components should be kept in a dry, temperature-controlled environment away from direct sunlight and corrosive substances. Avoid stacking units to prevent deformation of the housing or damage to the CHRA assembly. Regular inventory rotation ensures older stock is used first, reducing the risk of moisture buildup or seal degradation. When handling, use gloves to prevent contamination from skin oils, and store units in their original packaging until ready for use. For bulk orders, palletized storage with desiccant packs helps maintain optimal humidity levels and protects against rust on metal surfaces.
