Where is the cabin air filter located in the Audi A6L?

Audi A6L's cabin air filter is located at the air intake and blower of the air conditioning system. The replacement steps are as follows: 1. The cabin air filter is above the passenger side footwell, covered by a trim panel. The panel is secured by two plastic screws that can be unscrewed by hand. 2. After removing the panel, you will see a rectangular cover. Press the clip on the right side of the cover to remove it. 3. Pull out the old cabin air filter and replace it with a new one. 4. Reassemble in the reverse order. 5. Please note there are two types of cabin air filters: one without activated carbon and another with activated carbon. The activated carbon cabin air filter can absorb dust particles, alleviate respiratory discomfort, reduce irritation for allergy sufferers, and eliminate odors.
I've been driving an Audi A6L for many years, and the cabin air filter is usually located in the footwell area on the passenger side. Open the passenger door, bend down to look underneath, and you'll see a plastic cover or panel that can be gently pried open by releasing its clips to reveal the filter slot. It processes the air entering the vehicle. If not replaced for a long time, it can accumulate dust, pollen, and even mold, causing unpleasant odors and affecting respiratory health—especially for those with sensitive constitutions who may experience sneezing or allergies. I recommend checking it every 12 months or 15,000 kilometers. Replacing it yourself is quite simple: just purchase an OEM filter, use a Phillips screwdriver to remove the screws, and insert the new filter into the slot. When parking, avoid areas with fallen leaves to prevent debris from clogging the intake. This kind of maintenance can improve AC efficiency and even save fuel.
