Audi A3 cabin air filter is located under the glove compartment on the passenger side. The cabin air filter serves the following 5 functions: 1. Ensures unfiltered air doesn't enter the cabin: It seals tightly with the housing to prevent unfiltered air from entering the vehicle interior; 2. Filters out dust, pollen and other solid particles: It separates dust, pollen, abrasive particles and other solid impurities from the air; 3. Absorbs moisture, soot, ozone etc.: It absorbs moisture, soot, ozone, odors, carbon oxides from the air, with strong and lasting moisture absorption capability; 4. Prevents windshield fogging: Maintains clear driver visibility to ensure driving safety, provides fresh air to the cabin, prevents inhalation of harmful gases, and effectively sterilizes and deodorizes; 5. Maintains clean cabin air: Prevents bacterial growth to create a healthy environment, intercepts pollen to ensure passengers don't experience allergic reactions that could affect driving safety.
I remember when my Audi A3's air conditioning started emitting a strange odor, I decided to check the location of the filter myself. In the A3, the cabin air filter is hidden behind the glove compartment on the passenger side, where there's a dedicated panel. To access it, you first need to remove the glove compartment, which is quite simple: pull the glove compartment drawer to its maximum opening, then press the clips on both sides inward with both hands, and the entire compartment can slide out or flip open. The filter housing is right behind it, and you can see the filter element by removing the cover. I recommend replacing it regularly every 10,000 kilometers or every six months, especially in cities with heavy pollution, as the filter gets dirty too quickly and can affect the air quality inside the car, making it easier to get headaches or catch a cold. It's better to wear gloves when handling it to avoid scratching the interior.
Just helped a friend with the Audi A3's cabin air filter issue, located behind the glove compartment in front of the passenger seat. You need to open the glove box and remove it by releasing the two plastic clips on both sides. The filter housing is inside that cavity, just pull the tab to open it. Remember, a regular Phillips screwdriver is all you need, and a beginner can get it done in five minutes. I checked and this design is quite common in the A3, similar to other Audis like the A4, but older models might be a bit more complicated. Don't skimp on replacing the filter—OEM filters are durable and hypoallergenic, so avoid cheap knock-offs. They work great on days with poor air quality, filtering out pollen and dust effectively. Change it early to enjoy a comfortable drive, and don't wait until the fan starts buzzing to fix it.
During regular car maintenance, I found that the cabin air filter of the Audi A3 is quite easy to locate behind the glove compartment on the passenger side. I've tried replacing it myself twice—the position isn't hidden at all; you just need to flip down the glove box to see the filter cover. Apply some pressure to release the clips and pull it out. It's recommended to check it every 10,000 kilometers or so. If the filter turns black, it's time for a replacement, otherwise, the air quality deteriorates, affecting respiratory health. Changing the filter is straightforward. Buying a compatible model online costs less than 100 yuan. While you're at it, clean the dust from the air intake to help the car cool faster in summer. Fellow drivers, don't be lazy—maintaining your AC's efficiency can save fuel.
