Where is the air filter located in an Audi A6?

Audi A6L has air filters at both the air intake and the blower of the air conditioning system. The air filter in the engine compartment is located at the lower left of the cover plate in the engine compartment, while the blower air filter is above the passenger-side foot mat, covered by a trim panel secured with two plastic screws. Replacing the air filters in an Audi A6L does not require any tools. To replace the air filter in the engine compartment: 1. The air intake filter is located at the lower left of the cover plate in the engine compartment. First, remove the leftmost foam piece, then lift the sealing strip to open the cover plate and expose the air filter. 2. The air filter is housed in a rectangular frame. Release the fixing clips to remove the entire frame. 3. Replace with a new air filter and clean the air intake duct. 4. Reassemble in the reverse order. To replace the air filter at the blower: 1. The blower air filter is located above the passenger-side foot mat, covered by a trim panel secured with two plastic screws that can be unscrewed by hand. 2. After removing the panel, you will see a long rectangular cover. Press the clip on the right side of the cover to remove it. 3. Pull out the old air filter and replace it with a new one. 4. Reassemble in the reverse order.
In the Audi A6, the cabin air filter is located behind the glove compartment on the passenger side. I've been driving this car for several years, and changing the filter is always quite convenient. Open the glove compartment, locate the clips or retaining pins on both sides, press or twist them gently to remove, and you can directly see the air filter housing. Lift the cover to take out the old filter. This design allows owners to do it themselves, saving on repair shop costs. It's recommended to replace the cabin air filter once a year, especially in cities with high pollen or dust levels—not changing it can make the air inside the car stuffy and trigger allergies. I usually replace mine in spring and autumn. The filters are inexpensive, so I buy a few online to keep as spares. The whole process takes about ten minutes, and afterward, the airflow from the AC feels much fresher.
