Product Details and Attributes

This Dorman secondary air injection pump (part number 306-031) is supplied as a single unit without pulley or mounting hardware. It is engineered to integrate seamlessly with the emission control systems of compatible Audi and Volkswagen models. The absence of included pulley and mounting hardware means these components must be reused from the original pump or sourced separately to complete installation.

Function and Application

The secondary air injection pump is an essential component in the air injection system, which injects fresh air into the exhaust stream to promote the oxidation of unburned hydrocarbons and carbon monoxide. This process helps reduce emissions during engine warm-up phases.

• Helps reduce cold start emissions by injecting air into the exhaust manifold
• Supports compliance with emission regulations on compatible Audi and Volkswagen vehicles
• Addresses issues such as check engine light related to air injection system faults
• Can resolve symptoms like rough idle or failed emissions tests linked to pump failure
• Prevents potential damage to catalytic converters caused by incomplete combustion

Installation Notes and Tips

When installing the Dorman 306-031 secondary air injection pump, ensure that the original pulley and mounting hardware are in good condition or obtain replacements as needed. Proper alignment and secure mounting are critical for optimal pump operation. It is recommended to inspect related hoses and valves in the air injection system during installation to ensure overall system integrity.
