How to Remove the Air Filter of Mercedes-Benz R350?

Method for removing the air filter of Mercedes-Benz R350: First, use a screwdriver to pry open the clips on the inner side of the glove box. After opening the glove box, unclip the fasteners of the air filter cover plate. Once the cover plate is removed, the filter element can be seen and taken out. After removal, clean it by blowing off the dust or replace it directly. Taking the Mercedes-Benz R-Class 2006 R350 4MATIC as an example: It is an MPV launched by Mercedes-Benz (imported) with a length, width, and height of 5157mm, 1922mm, and 1661mm respectively, and a wheelbase of 3215mm. It is equipped with a 3.5L naturally aspirated engine, with a maximum power of 200kw, matched with a 7-speed automatic transmission.

I remember when I first bought this Mercedes-Benz R350, I was a bit nervous trying to replace the cabin air filter myself because it's located in the passenger footwell. You need to park the car on level ground, turn off the engine, open the passenger door, remove the floor mat, and then take off the plastic cover panel—usually just unscrewing the bolts with a T20 Torx screwdriver is simple. Then slowly pull out the old filter, being careful not to damage the connectors. Finally, insert the new filter in the direction of the arrow—the arrow must face the fan, otherwise the airflow will be incorrect and the performance will suffer. It took me half an hour the first time, but now I'm much more skilled. Don’t forget to replace it once a year to maintain fresh air, which is good for the respiratory system, especially if you have kids at home. Regular maintenance also extends the life of the AC system. Overall, it's not difficult, but beginners should be careful not to touch other wiring harnesses.

I've been driving a Mercedes for over ten years and am used to maintaining the cabin air filter myself. The removal and installation are quite convenient on the R350—it's located behind the side panel under the front passenger seat. Just prepare a basic tool kit, turn off the car, and get underneath. Remove the carpet cover, release two clips, and gently pull out the old filter. When replacing, pay attention to the directional arrow on the filter to ensure smooth insertion without forcing it, which could cause damage. I recommend using genuine parts or high-quality third-party alternatives—they're cost-effective and save the hassle of visiting a repair shop. Regular maintenance improves air quality, ensures smooth airflow, and enhances AC cooling efficiency. Replacement frequency depends on driving conditions; in urban areas, changing it every 15,000 km is sufficient. DIY saves both money and time.

Every time I change the air conditioning filter, I remind myself to operate safely on the Mercedes-Benz R350. This involves turning off the engine in the front right seat area, lying down to locate the protective cover, removing the screws, taking out the old filter, installing the new one (making sure not to put it in backwards with the arrow pointing towards the air outlet direction). Simple tools are all you need to get the job done. Regular replacement prevents odors and improves air quality—health comes first.
