The Air Pump Breather Pipe (OEM Part Number 06B133607N) is a critical component in the secondary air injection system, located between the secondary air pump and the exhaust gas recirculation (EGR) pipe on various Audi and Volkswagen models. This factory-original part ensures proper airflow and function, helping to reduce emissions and improve engine performance. Common issues that may necessitate replacement include cracks, leaks, and structural damage that can disrupt the flow of air. This breather line is compatible with Audi A4 and Cabriolet models from 2003 to 2006 (1.8L L4 - Gas) as well as the 2003 to 2005 Volkswagen Passat. Other interchange part numbers include 06B133607Q, further establishing its reliability. Take action if you notice your vehicle exhibiting rough idle, poor engine performance, or increased emissions, as these are signs of a failing air pump breather pipe.
