Audi A6 C6 Air Filter Replacement | Easy DIY Guide

Replacing the air filter on your Audi A6 C6 2.0 TFSI is one of the easiest DIY maintenance tasks—and it requires no tools at all!

According to the Audi A6 C6 2.0 TFSI service manual, the air filter should be replaced every 90,000 km (55,000 miles) to ensure optimal engine performance and fuel efficiency.

A clean air filter improves airflow to the engine, helps maintain power output, and can even contribute to lower fuel consumption. Over time, dirty filters restrict airflow, reducing performance.

1. Open the hood and locate the air filter box on the passenger side.
2. Unclip the cover of the air filter housing by hand—no screwdriver or wrench needed.
3. Remove the old air filter.
4. Insert the new air filter, ensuring it fits snugly in the housing.
5. Clip the cover back on securely.

That’s it! You’ve just performed a quick and essential maintenance task that keeps your car running smoothly.
