Where is the cabin air filter located in a BMW 320?
2 Answers
BMW 320's cabin air filter is located inside the glove compartment on the passenger side. The replacement steps are as follows: 1. Remove the dampers on both sides of the glove compartment and take out the glove box. 2. After removing the glove box, release the clip on the right side of the cabin air filter cover and remove the old filter. 3. When installing the new cabin air filter, ensure the arrow on the filter faces upward for optimal dust filtration. 4. Reinstall all removed components in reverse order. Important notes for cabin air filter replacement: 1. While DIY replacement is convenient, always verify the correct part number when purchasing. 2. Always choose reputable brand products, as inferior filters often have poor air permeability and lack proper dust adsorption capabilities.
My old BMW 320 also had the issue of locating the cabin air filter. It's positioned behind the glove compartment on the passenger side, and you need to be careful when removing it to avoid breaking the clips. Last time I replaced it myself, I first adjusted the seat backward to create space, then removed several screws at the bottom and side of the glove compartment to detach the entire glove box. The plastic cover behind it is the filter housing, which opens by pressing the clips. The whole process takes about half an hour, but the key is not to force anything. Also, don't skimp on cheap, low-quality filters—they not only reduce filtration efficiency but can also cause unpleasant odors from the air vents. Doing it yourself saves hundreds compared to a dealership service, but the first-time removal and installation require some patience.
