Where is the A4 air conditioning filter located?
4 Answers
The A4 has two air conditioning filters. Open the front hood, and you will find a black elongated panel under the windshield. Beneath this panel is the external filter. The internal filter is located in the front passenger footwell, and you can see it by removing a small black cover. The air conditioning filter is a type of filter installed in the car's air conditioning system. It can absorb dust particles, reduce respiratory discomfort, minimize irritation for allergy sufferers, and protect the air conditioning cooling system. The A4 is a model under FAW-Volkswagen's Audi brand, with body dimensions of 4818mm in length, 1843mm in width, and 1432mm in height, and a wheelbase of 2903mm. In terms of appearance, the A4 might even be confused with the A6 from a distance, as Audi's front-end designs are very similar. The advantage is strong brand recognition, but the downside is the lack of distinctiveness.
I've been in the auto repair business for many years, and I could find the cabin air filter location of an Audi A4 with my eyes closed. It's right beneath the windshield inside the wiper cowl panel. You'll need to remove the wiper arm screws first, then pry open the cowl panel to reveal the filter tucked inside that small compartment. The replacement is quite straightforward - usually just a Phillips screwdriver will do the job. Never forget to check if the sealing gasket is intact, otherwise rainwater will definitely seep in and cause problems. I recommend changing it every 15,000 kilometers or once a year. When this filter gets dirty, the air turns foul and can easily trigger respiratory issues. During routine maintenance, taking a moment to clear debris around it can extend its lifespan.
As a veteran owner of an Audi A4 for eight years, I've personally replaced the cabin air filter several times. It's located at the front of the engine compartment, right under the windshield. The first attempt was a bit clumsy and took me half an hour, but now I can get it done in just five minutes with practice - mainly dealing with those plastic clips. I make sure to replace it every two years to prevent musty air from affecting health, especially since breathing fresh air during traffic jams feels so good. The location is reasonably designed and easier to find than some deeply hidden models, but remember to turn off the engine before replacement to avoid electric shock. Buying the filter yourself costs very little, much cheaper than going to a shop.
As a newbie just getting started with the Audi A4, I was completely clueless about these parts. The cabin air filter is located under the wiper area at the base of the windshield. After opening the hood, look at the front windshield section—there's a small cover that, once removed, reveals the filter housing. Don't worry about the process being complicated; just make sure to turn off the engine and disconnect the power before starting for safety. The location follows a standard design and is easy to find. I recommend replacing it once a year, as neglecting this can lead to dust clogging, rapidly reducing AC efficiency and affecting daily driving comfort. Many first-time drivers overlook this, resulting in strong odors inside the car.
