The Audi A3 is a compact sedan produced by FAW-Volkswagen Audi, available in both sedan and hatchback versions. In terms of power, the Audi A3 offers a choice between a 1.4-liter turbocharged engine and a 2.0-liter turbocharged engine, with the 1.4-liter version producing a maximum horsepower of 150 and the 2.0-liter version producing a maximum horsepower of 190.
I enjoy doing car maintenance myself, and changing the air conditioning filter for an Audi A3 is quite simple. The location may vary slightly depending on the car's age, but it's generally under the glove compartment on the passenger side. First, make sure the car key is placed without starting the engine, then carefully move aside the carpet or side trim panel—some models require gently prying open the panel with a tool. The key is using a T20 Torx screwdriver to remove the screws and take out the old filter, paying attention to the arrow direction to avoid installing it backward, as this directly affects filtration efficiency. Opt for an activated carbon filter like Mann-Filter, which is more durable and absorbs odors better than standard ones. When reinstalling, clean any dust buildup, then reassemble the panel and glove compartment. After finishing, test the airflow by turning on the AC to ensure smooth operation. DIY replacement saves money and time—done in under half an hour, with filter costs just a few dozen yuan. Remember to replace it every year or 15,000 km, especially before pollen season, as it greatly benefits health by preventing allergies or bacterial growth that could affect cabin air quality.
As a frequent visitor to repair shops, the experience with the Audi A3's cabin air filter is that it needs to be accessed from the passenger side. Remove the seat and the cover panel under the glove box, typically secured with T20 screws. Carefully take out the old filter to avoid letting dust fall into the ducts, clean the surrounding area thoroughly, and then install the new filter—make sure the arrow points in the direction of airflow; otherwise, it won't work properly. After installation, securely fasten the panel and test the air conditioning for any unusual noises. Throughout the process, be careful not to scratch the interior or bump into anything, and standard household tools are sufficient. The recommended frequency for filter replacement is as per the manual, approximately every 15,000 km. Opt for OEM or compatible brands like Bosch, preferably the activated carbon type to prevent pollution. Regular replacement reduces dust and bacterial buildup inside the car, extends the lifespan of the air conditioning system, and prevents odor issues. Doing it yourself can save you around a hundred bucks in maintenance costs, and even beginners can give it a try with caution.
