Detailed Description

This Pierburg secondary air injection control valve is used in emission control systems to manage air delivery during engine warm-up. By controlling airflow in the secondary air injection circuit, it helps maintain proper system operation on vehicles such as the Audi Q5, Audi S4, Porsche Cayenne, and Volkswagen Touareg when the original valve is worn, sticking, or no longer sealing correctly. The pneumatic, non-return valve construction supports one-way flow control, and the included seal helps restore a tighter connection at the mounting point. OE-number matching is important for these applications, so verify against the listed references before ordering. Part number 7.22286.52.0 is specified for multiple Audi, Porsche, and Volkswagen fitments across the 2008-2018 model years.

What It Helps Fix

• Secondary air injection fault codes related to airflow control
• Rough cold-start emissions system operation
• Air leakage at the valve sealing surface
• Sticking or failed one-way valve function
• Check engine lights tied to secondary air injection performance

Installation Notes and Tips

Confirm the OE number on the original valve before installation, especially on Audi A4 Quattro, Audi A6 Quattro, Audi Q7, Porsche Panamera, and Porsche Cayenne applications. Inspect the surrounding hoses, connectors, and mounting surfaces for wear or contamination before fitting the new valve. Because this is a pneumatic valve, proper hose routing and secure sealing are important for correct operation. Use the listed OE references and Technical Information Number SI 0106-11 to verify application details.

Quality Assurance

Pierburg manufactures emission control components for OE-style replacement applications, and this valve is built to the specified part and OE-number references for accurate fitment verification.
