Replacing the Air Filter on Mercedes Class B

Model: Mercedes Classe B W246, MK 2 - Years 2011-2019
Part: Air filter

It is recommended to use filter LX3471. Using a T25 Torx bit, unscrew the screws securing the air filter box cover. Detach the small duct next to the box, as shown in the video, and uncover the engine air filter compartment (the cover is held in place not only by the aforementioned screws but also by small rear clips, so be careful when removing it). Remove the used filter and insert the new one you purchased. All done! Just reassemble the cover in reverse order, screw in the screws, and reattach the side duct to the box.
