Where is the cabin air filter located in the BMW 528 Series?
2 Answers
The cabin air filter in the BMW 528 is located inside the glove compartment. Open the glove box and remove the rear panel of the glove box to access it—no tools are required, and the process is straightforward. Here are the detailed steps to replace the cabin air filter: 1. First, open the glove compartment cover. 2. Locate the clip on the right side and pull it out firmly. 3. Then, remove the securing clip to detach it. 4. Next, squeeze the glove box toward the center to release and remove it. 5. After removing the glove box, you will find the cabin air filter cover. Press firmly on the securing clips on both sides of the cover to release it. 6. Finally, pull out the cabin air filter.
I used to own an older BMW 528, and the cabin air filter was located above the footwell on the driver's side. I remember it took quite some effort to find it the first time—you had to remove the decorative panel under the glovebox and pry open the side cover to access it. The placement was quite hidden, requiring you to half-lie on the carpet to reach in and feel around inside the trim panel gaps. I recommend checking it during seasonal transitions, especially in northern areas where spring brings lots of willow catkins. If the filter gets clogged, the AC airflow weakens noticeably, and you might even detect a musty odor from the vents. If you're replacing it yourself, keep a T20 screwdriver handy. There are online tutorials for model-specific replacements, saving you hundreds compared to a dealership visit.
