Where is the cabin air filter located in the Audi A4L?
2 Answers
The Audi A4L has cabin air filters installed at both the air intake vent and the blower motor. Compared to other models that only have a filter at the blower motor, this dual-filter setup provides better filtration of airborne particles like dust and pollen. The air intake filter is located under the left side of the engine compartment cover. To access it, first remove the leftmost foam piece, then lift the rubber seal to open the cover and reveal the filter. The Audi A4 is a mid-size sedan produced by Audi, with dimensions of 4818mm in length, 1843mm in width, 1432mm in height, and a wheelbase of 2908mm.
I've been driving an Audi A4L for almost ten years, and the cabin air filter is located behind the glove compartment on the passenger side. First, empty the glove box, press the clips on both sides to lower it, and you'll see a rectangular plastic cover—that's the filter housing. Use a T20 screwdriver to remove the cover. When pulling out the old filter, pay attention to the arrow direction, and insert the new filter the same way. The location is similar for B8 and B9 models, but older versions may require removing the waterproof panel under the hood. DIY replacement can save you 300-400 yuan in labor costs, and a Mann filter bought online for 70-80 yuan works just fine. Remember to replace it before each rainy season, otherwise, the AC may develop a musty smell.
