VAG Secondary Air Pump - 04E131333A

The secondary air injection system, often referred to as the air pump, is a vital component of your vehicle's emissions control system. Its primary function is to inject fresh air into the exhaust system during the initial stages of engine operation, particularly when the engine is cold. This injection of air helps to rapidly heat up the catalytic converter, allowing it to begin its work of converting harmful pollutants into less harmful substances more quickly. When the secondary air pump fails, it can lead to increased emissions, illuminated check engine lights, and potentially affect engine performance. Replacing a faulty pump with a genuine VAG part like the 04E131333A ensures compatibility and maintains the integrity of your vehicle's emissions control strategy. This specific VAG Secondary Air Pump is engineered to meet the stringent quality and performance standards set by the manufacturer. It is designed for a precise fit and reliable operation, ensuring that your vehicle continues to meet emissions regulations and performs as intended.
