Detailed Description

Rotomaster K1030204N is a new turbocharger cartridge designed for repair of the turbocharger core rather than full unit replacement. When the cartridge is the only damaged section, this approach helps reduce repair time and preserves the original housings. It is a practical solution for Audi A4 turbocharger cartridge replacement and Audi A4 Quattro turbocharger cartridge service where the housing components remain serviceable.

This part cross-references Monroe Shocks & Struts (e.g., N103204C) for the same application. The K1030204N part number should be verified against the vehicle’s turbocharger configuration before ordering.

What It Helps Solve

• Turbocharger core wear or internal cartridge damage
• Loss of boost caused by worn rotating components
• Oil- and coolant-cooled turbocharger service needs
• Repair jobs where the compressor and turbine housings can be reused
• Full turbocharger replacement when only the cartridge requires service

Installation Notes and Tips

Confirm the turbocharger part number and vehicle application before installation. This cartridge is intended for 2005-2009 Audi A4 and 2005-2009 Audi A4 Quattro applications, and fitment notes indicate special order availability should be confirmed with a sales representative. Inspect the original compressor and turbine housings for damage, contamination, or excessive wear before reuse. Clean oil supply and return passages, verify coolant flow, and follow proper turbocharger service procedures during installation of K1030204N.

Quality Assurance

Rotomaster assembles this cartridge with O.E.-grade components to support durability and consistent performance in turbocharger repair applications. The journal bearing design and oil/coolant cooling layout reflect the requirements of the original turbocharger system.
