Where is the cabin air filter located in the BMW X3?
2 Answers
The cabin air filter of the BMW X3 is located inside the grille box beneath the wipers. Open the engine hood and remove the two upper sealing strips to reveal the box containing the cabin air filter. The BMW X3 is a mid-size 5-door, 5-seat SUV with body dimensions of 4717mm in length, 1891mm in width, and 1689mm in height, with a wheelbase of 2864mm and a fuel tank capacity of 65 liters. The BMW X3 is equipped with a 2.0T turbocharged engine, delivering a maximum power of 135 kW and a maximum torque of 290 Nm. It features a double-joint spring strut front axle for the front suspension and a multi-link independent suspension for the rear suspension.
I've been driving a BMW X3 for many years and have replaced the cabin air filter several times myself. The filter is located mainly under the footwell area on the passenger side. You'll need to remove the floor mat or lift the carpet panel first. Specifically, there's a plastic cover near the door-side footwell that can be opened by gently prying with a small tool. Inside is the filter slot - make sure not to install it backwards as this will obstruct airflow. I change my filter frequently because Beijing's poor air quality causes rapid dust accumulation, which affects respiratory health. I do this every six months. The whole process only requires basic tools like a screwdriver or pry bar - DIY saves money and is quick. Important reminder: first remove the glove compartment's mounting screws before accessing the filter cover position, otherwise components may get stuck. Always turn off the AC system before starting for safety.
