The cabin air filter in the Audi A6 is located inside the glove compartment on the passenger side. Below is an introduction to the functions of the cabin air filter: 1. Providing fresh air: It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensuring safety and hygiene: It keeps the cabin air clean and prevents bacterial growth, creating a healthy environment; it effectively separates solid impurities such as dust, powder, and grinding particles from the air; it efficiently blocks pollen, ensuring that passengers do not experience allergic reactions that could affect driving safety. 3. Adsorbing harmful substances: It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, and other substances from the air; it has strong and durable moisture adsorption capabilities. 4. Filtering solid impurities: The car's cabin air filter fits tightly against the housing, ensuring that unfiltered air does not enter the cabin. It separates solid impurities such as dust, pollen, and grinding particles from the air.

Speaking of my 2020 Audi A6L, the cabin air filter is hidden behind the glove compartment on the passenger side. Open the glove box, and you'll see several screws holding it in place—just unscrew them to gently pull out the entire glove box module. Be careful not to force it, as the plastic parts might crack. The filter housing will then be exposed at the bottom. Lift the cover, remove the old filter, and simply slide the new one in. I changed it myself shortly after buying the car, and it took less than 20 minutes—pretty straightforward. Regular replacement is crucial; otherwise, a clogged filter accumulates dust, making the air blown into the cabin sticky and hard to breathe. I recommend setting aside some free time to do it yourself—it saves money and teaches you a handy skill, much more cost-effective than visiting a repair shop. The filter's location is quite user-friendly, and once you know where it is, future maintenance becomes a breeze.

As a seasoned driver who has driven many cars, the cabin air filter of the Audi A6L is located behind the glove compartment on the passenger side. The operation is quite straightforward: open the glove compartment, release the clips to remove it, and the filter housing becomes visible. When I changed it myself, I applied a bit too much force and ended up breaking a clip, but being more careful next time did the trick. The location is pretty standard, similar to most car designs. While replacing the filter, I also took the opportunity to clean out the clutter inside the glove compartment, making the air in the car much fresher. It's best to replace it during spring or autumn when there's less dust to clog it up, and the air conditioning runs more comfortably. Remembering the location is beneficial because once any odd smells appear, you can tackle the issue immediately. Experience tells me that once you're familiar with the location, everything becomes simple.

I drive to work every day, and the most annoying thing is the weird smell from the air conditioning. The cabin air filter of the 2020 Audi A6L is located behind the right glove box. Just open the glove box, unscrew the bolt, and it comes off easily. Lift the filter box cover, pull out the old filter, push in the new one, and the job is done. The location is simple and easy to find. Remember to turn off the engine when doing it yourself to avoid electric shock. After replacing the filter, the air becomes fresher and breathing healthier, especially when kids are in the car—no more worries about allergies. It's recommended to check the location regularly and not overlook it.
