3 Answers
BMW M4 cabin air filter is located inside the glove compartment in front of the front passenger seat. To replace it, you need to remove the glove compartment, then you can see the cabin air filter inside, generally positioned at the lower left side. The function of the car cabin air filter is to filter and absorb various dust and harmful substances from the outside air, providing a better driving environment for the occupants. The BMW M4 is an imported sedan, available in coupe and convertible versions. In terms of body dimensions, the BMW M4 measures: coupe 4678mm in length, 1870mm in width, and 1394mm in height; M4 convertible 4678mm in length, 1870mm in width, and 1398mm in height.
I remember helping my friend with his BMW M4's cabin air filter issue before. That thing is usually hidden behind the glove compartment in the passenger cabin. You'll need to open the glove box and look carefully inside—there are some clips or covers securing it, which can be gently pried open to reveal the filter tucked in there. I recommend replacing it at least once a year, especially in cities with poor air quality, otherwise it can cause unpleasant odors inside the car and even affect health. The filter isn't expensive, and it's pretty straightforward to DIY—just have a screwdriver handy, but be careful not to damage any wiring connections. After replacing the filter, turning on the AC feels much fresher—it's good for the car and saves money. Regular checks can also prevent future AC system issues, making it a habit worth keeping.
As a long-time BMW enthusiast, I'm very familiar with the location of the cabin air filter. On the BMW M4, it's typically located near the windshield wiper module in the front of the engine compartment, just below the windshield. You can access it by removing the wipers and the cover panel – it's nestled in a slot. When driving frequently on highways or in polluted areas, the filter tends to clog up with dust, which can affect cooling efficiency and breathing comfort. I usually keep a spare filter on hand and replace it myself when needed, but be cautious around the engine compartment wires and components – handle them gently. It's best to replace it every 10,000 kilometers to prevent bacterial growth and avoid unnecessary fuel and battery consumption. Regular maintenance of this component ensures worry-free driving, even on long trips.
