The cabin air filter in the S6 is located beneath or inside the glove compartment on the passenger side. Failure to properly maintain the cabin air filter can lead to accumulation of dust and dirt on the filter screen, radiator, evaporator, and fin surfaces, resulting in airflow blockage. This may cause reduced cooling/heating efficiency, increased power consumption, noise issues, and shortened service life of the air conditioning system. Functions of the cabin air filter: 1. Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc. in the air; 2. Ensures clean cabin air free from bacterial growth, creating a healthy environment; 3. Effectively filters out solid impurities like pollen and abrasive particles, preventing allergic reactions that could compromise driving safety.

I've been driving a S6 for eight years and know the AC filter replacement like the back of my hand. It's right behind the glove compartment on the passenger side - super easy DIY job. Just open the glove box, pinch the clips on both sides inward, and the entire compartment will lower down. You'll see a black plastic cover panel; press open the two small clips on its edges to remove it. When pulling out the old filter, remember to check the arrow direction on its side - that's the airflow direction. Insert the new filter in the same orientation, snap the cover back on, and push the glove compartment into place. Best to replace it every six months - buying the same model online costs just 20-30 yuan, saving you over a hundred compared to dealership service. Avoid changing it on humid days to prevent debris from getting in.

I just replaced the cabin air filter for my old S6 last month. It's located inside the glove compartment on the passenger side, requiring the entire glove box to be removed. After opening the glove box, there are stoppers on both left and right sides - squeeze them simultaneously towards the center to release the glove box from its clips. Once fully lowered, you'll see a rectangular cover panel. Unclip and remove this panel to reveal the filter slot. Remember to take a photo of the old filter's orientation before pulling it out, and install the new filter facing the same direction. I recommend purchasing a dual-effect filter with activated carbon to eliminate odors. The whole process takes about ten minutes and is easy enough for women to handle. Just make sure to align the glove box properly with its tracks when reinstalling.

When my S6's AC had an odd smell, the technician showed me the filter location. It's behind the glove compartment in front of the passenger seat. Empty the glove box, firmly press the clips on both sides to release them from their stops. After fully lowering it, locate the AC duct cover panel, unclip the fasteners to remove the filter. Be careful not to install it backwards - airflow typically goes from the front grille toward the cabin. DIY replacement costs under 30 yuan, while dealerships charge 150. Turn off AC power before starting, and wear gloves to avoid scratches. Recommended to replace each spring and autumn, especially before rainy seasons.

As an owner of the older S6 model, replacing the cabin air filter requires removing the glove compartment on the passenger side. Specifically, after opening the glove box door, press the plastic clips on both sides inward while pulling the glove box downward to detach it. Once fully lowered, the filter compartment cover will be exposed. Pry open the three clips to remove the old filter. Install the new filter with the arrow mark facing toward the rear of the car—this orientation is crucial. Be careful not to let leaves or dust fall into the air ducts during the process; it's best to perform this task in a garage. Although the filter is inexpensive, it effectively blocks dust and pollen, improving the air quality inside the vehicle.

I helped a friend replace the air conditioning filter in a S6. It's located behind the glove compartment on the passenger side, requiring the removal of the entire glove box module. On the inner top of the glove box, there are two buffer latches—squeeze to unlock and pull down completely. After exposing the white filter frame, pull out the cover plate to find the old filter covered in dust and dead insects. When installing the new filter, follow the arrow direction on the side to ensure proper filtration. It's recommended to replace it before using the AC in summer, while the interval can be slightly extended in winter. If the glove box is difficult to reset, spraying some lubricant on both slide rails will make it much smoother. After this operation, the air from the AC feels much fresher.
