Step-by-Step Instructions
Follow these steps carefully
1
Prep and count the filters
Park on level ground, brake set, engine off and cool. The xDrive40i (3.0L turbo six) takes a single panel filter; the V8 xDrive50i/M50i takes two, one per bank — count filters before buying. The xDrive45e hybrid uses the single-filter layout.
🔧 Mechanic's note — Tom Becker
In my experience, xDrive45e owners, your engine bay runs the same single-filter B58 layout as the xDrive40i — buy one filter and follow these steps exactly.
2
Open the air filter housing
Back out the lid screws — they stay captive. Lift the lid straight and steady, never rocking it. If a clamp or brace blocks the lid, loosen it and lift the cover just enough to work.
3
Remove the old filter and clean
Lift the filter out — both filters on V8 models — noting the orientation, and confirm the new ones match. Vacuum the housing and wipe the sealing lip, keeping grit out of the intake.
4
Install the new filter
Seat the new filter with the rubber seal in the groove, matching the old orientation, and press it flat — no force needed. A crooked filter stops the lid sealing and can set a check-engine light.
5
Reseal and verify
Lower the lid and snug the screws evenly — firm is enough in plastic. Retighten any hose clamp you loosened, then start the engine and listen for whistling. If it persists, a shop smoke test will pinpoint the leak.
🔧 Mechanic's note — Ray Delgado
If the whistle survives reassembly, don't keep tearing it apart — a shop smoke test finds the leak in minutes. I've burned an hour chasing a noise a smoke machine caught in two.
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 upside down or unseated so unfiltered air bypasses the element
- • Leaving debris in the housing that then gets sucked into the intake
- • Forcing clips/screws and cracking the plastic air box lid
- • Reusing a heavily clogged filter instead of replacing it
