Step-by-Step Instructions
Follow these steps carefully
1
Prep and open access
Park the 5 Series, brake set. The F10 does NOT use a behind-glovebox filter — it uses two microfilters under the hood, one per side of the cowl at the windshield base. Open the hood and find the two cover panels.
🔧 Mechanic's note — Ray Delgado
Two microfilters, one per side — buy the pair. I have watched people replace the driver's side and leave a blackened passenger filter in place, then wonder why the cabin still smelled.
2
Open the filter covers
On each side, pull the wire latch at the front of the cover forward, then lift the cover open. Keep both covers and latches together — one per side. Brush leaves from around the housing openings first.
3
Remove the old filters and clean
Lift the dirty microfilter out of each housing, noting the orientation so the replacements go in the same way. Clear leaves and debris from the empty housings so nothing falls into the HVAC intake — F10 cowls collect leaves that rot against the filter.
4
Install the new filters
Install a new microfilter in each housing, matching the old orientation so the airflow arrows point correctly. Charcoal-activated microfilters are the factory-style choice and add odor reduction — plain paper fits the same housings. Seat each fully so it seals without gaps.
5
Reassemble and verify airflow
Close both covers, re-hook their latches, and close the hood. Start the 5 Series on fresh air through several fan speeds: strong, clean airflow, no whistling. Note: the F10's recirculation filters under the dash are a separate, more involved service.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Installing the filter backwards (ignore the airflow arrow)
- • Forcing a thicker filter so the door will not latch
- • Tearing glovebox stops, dampener arms, or filter-door clips
- • Leaving leaves and debris in the housing so they blow into the cabin
