Where is the cabin air filter located in an Audi A4?
2 Answers
The Audi A4 has two main cabin air filters, located in the following positions: 1. Intake air filter. This filter is situated at the lower left side of the engine compartment cover panel. 2. Blower filter. This filter is located above the footwell on the front passenger side. Additional information: 1. In addition to the cabin air filter, there is also a particulate filter that significantly reduces or blocks contaminants from outside air entering the vehicle interior. The particulate filter element must be replaced at intervals specified in the maintenance manual to maintain the air conditioning system's effectiveness. 2. If the filter's effectiveness diminishes prematurely due to excessive pollutants in the vehicle's external environment, the filter element should be replaced even between scheduled maintenance intervals.
When I first drove the Audi A4, I researched the location of the cabin air filter. It's located under the footwell on the passenger side, specifically hidden behind the glove compartment. You'll need to remove the glove box first (be careful not to break the plastic clips), and then you'll see a cover. Open it to reveal the filter. I've changed it several times and think replacing it every 20,000 kilometers is ideal—otherwise, the car may develop odors or cause dust allergies. Don’t forget to wear gloves to avoid scratching your hands. Clean air makes driving much more comfortable and benefits your health. I heard the location hasn’t changed much in the newer A4 models, but it’s best to check the manual to confirm.
