The cabin air filter of the BMW 1 Series is located behind the glove box on the passenger side. Here is a related introduction to the functions of the cabin air filter: 1. Provide fresh air: It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving. It supplies fresh air to the cabin, prevents occupants from inhaling harmful gases, enhances driving safety, and effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: It maintains clean cabin air and prevents bacterial growth. It effectively filters out dust, pollen, grinding particles, and other solid impurities, intercepts pollen, and ensures that passengers do not experience allergic reactions that could affect driving safety. 3. Adsorb harmful substances: It adsorbs soot, ozone, odors, CO2, and other harmful substances from the air, as well as strongly and durably absorbs moisture.
I've been driving a BMW 118i for a while and often check the air filter location myself. I remember when I first looked for it, I opened the hood and stood at the front of the car. It's generally located at the front left of the engine bay, right next to the driver's side. The air filter is hidden inside a black plastic box, which is rectangular in shape and usually secured with clips or screws. You'll need to first remove the decorative panel or air deflector on the engine cover to see that box. It's best to wear gloves during the operation to avoid scratches. Once you lift the box lid, you can replace the filter element. Normally, it should be replaced every 20,000 kilometers; otherwise, dust blockage can affect the engine's air intake efficiency, leading to increased fuel consumption and insufficient power. I noticed more dust coming from the air vents when driving with headlights on the highway, which reminded me to clean the air filter promptly.
