VAG Secondary Air Pump System Valve 078131101AC

The VAG Secondary Air Pump System Valve, part number 078131101AC, is a critical component designed to regulate the flow of air into your vehicle's exhaust system. This valve plays a vital role in the secondary air injection (SAI) system, which is responsible for reducing harmful emissions during cold starts. By injecting fresh air into the exhaust manifold, the SAI system helps to burn off uncombusted fuel, thereby lowering the levels of pollutants like hydrocarbons and carbon monoxide. The secondary air pump system valve precisely controls when and how much air is injected, ensuring optimal emission reduction without negatively impacting engine performance. This VAG original part guarantees a perfect fit and reliable operation, maintaining the integrity of your vehicle's emissions control system. Replacing a faulty valve is essential to prevent check engine lights, improve fuel efficiency, and ensure compliance with environmental regulations.
