Where is the cabin air filter located in a Porsche Cayenne?
2 Answers
Porsche Cayenne's cabin air filter is located beneath the glove compartment on the passenger side. Open the black plastic panel at the passenger footwell to access the cabin air filter. Here are some relevant details about the cabin air filter: 1. Owners should inspect and replace the cabin air filter according to the maintenance schedule. If the owner lives in a city with poor air quality, the cabin air filter should be replaced twice a year. 2. If there's a significant reduction in airflow from the AC vents, the cabin air filter might be clogged. First clean the filter, then replace it if necessary. 3. Operating the AC system without the cabin air filter installed may degrade dust protection performance and affect AC system functionality.
I remember when I last studied the Cayenne's air conditioning system design, I found that the cabin air filters are mostly hidden behind the air intake under the windshield. To access it, you need to lift the hood and remove the plastic cover on the passenger side. Before starting, remember to disconnect the negative battery terminal—those fragile plastic clips underneath the cover are particularly easy to break. Many people complain that replacing the Cayenne's filter is troublesome, mainly because the design prioritized the sealing of the intake ducts. By the way, if leaves accumulate here and aren't cleaned promptly, the filter will wear out prematurely.
