If you own a Mercedes-Benz, you’ve probably heard of the secondary air injection pump. This crucial component plays a vital role in reducing emissions during cold starts. But what happens if your Mercedes-Benz secondary air pump is not fixed? Ignoring this issue can lead to a cascade of problems, impacting your vehicle’s performance and your wallet.

Understanding the Secondary Air Pump’s Role

This extra oxygen helps burn off uncombusted fuel, significantly reducing harmful emissions. It’s a key part of your Mercedes’ emissions control system and contributes to a cleaner environment.
