VW Air Pump Control Valve - Genuine VW 07K131351C

Product Information

The secondary air injection pump check valve helps reduce emissions by injecting extra air into the exhaust stream during cold starts. This additional air aids in burning any unburned fuel and reduces harmful emissions, particularly carbon monoxide and hydrocarbons, before the catalytic converter reaches operating temperature. The check valve is responsible for directing air into the exhaust and preventing exhaust gases from flowing back into the air injection pump.

• Check Engine Light: A common sign of a faulty check valve is the check engine light illuminating. The ECU will detect issues with the air injection system and log related error codes, such as P0410 or P0411
• Poor Engine Performance: When the check valve fails, you may experience rough idling, hesitation, or reduced acceleration, as the secondary air injection system plays a role in optimizing cold starts and early engine efficiency
• Increased Emissions: A failed check valve can lead to a rise in emissions due to unburned fuel in the exhaust. This issue might only be noticeable during an emissions test, but if left unresolved, it can impact the catalytic converter over time.

About Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
