Where is the cabin air filter located in the Audi A4L?
2 Answers
The Audi A4L is equipped with cabin air filters at both the air intake vent and the blower motor, unlike some models that only have a filter at the blower motor. This dual-filter setup provides better filtration of airborne particles such as dust and pollen. Below are the steps to replace the cabin air filters in the Audi A4L: 1. Replacing the air intake vent filter: The air intake filter is located at the bottom left of the engine compartment's cover panel. First, remove the foam piece on the far left, then lift the sealing strip to open the cover panel and access the filter. The filter is housed in a rectangular frame - release the frame's securing clips to remove the entire assembly. Install the new filter and clean the air intake duct before reassembling in reverse order. 2. Replacing the blower motor filter: The blower motor filter is located above the front passenger footwell, concealed behind a trim panel secured by plastic screws that can be unscrewed by hand. After removing the panel, you'll see a rectangular cover - press the clip on the right side of the cover to remove it. Pull out the old filter and install the new one, then reassemble following the reverse procedure.
As a long-time A4L owner with 10 years of experience, let me share the location of the cabin air filter. It's right behind the glove compartment—pretty easy to find. First, open the glove box and firmly press outward on both plastic clips until they pop open with a click. Then carefully pull down to remove the glove box itself, revealing a rectangular plastic cover. Pry it open to access the filter. Remember, don't yank it forcefully—you might break the clips. I change mine every spring; if you don't replace it in dusty environments, the AC starts emitting odors that affect respiratory health. DIY replacement is super cost-effective—filters cost around 20 yuan online, and the job takes just 20 minutes, saving you unnecessary dealership expenses. In short: the location is hidden but easy to handle. Proper filter maintenance makes cabin air many times fresher, ensuring comfort on long drives.
