The air conditioning filter of the V260 is located inside the glove compartment in front of the front passenger seat, making it relatively simple to replace. The Mercedes-Benz V260 is an MPV with body dimensions of 5370mm in length, 1928mm in width, and 2100mm in height. The V260 is equipped with an M274L 4-cylinder turbocharged direct injection engine. Relevant information about automotive air conditioning filters is as follows: 1. Introduction: An automotive air conditioning filter is a specialized filter designed for air purification within the vehicle cabin. It utilizes activated carbon composite filter material made from highly efficient adsorption materials like activated carbon combined with long-fiber non-woven fabric, featuring a compact structure. 2. Function: It effectively filters smoke odors, pollen, dust, harmful gases, and various odors. The filter can also efficiently trap and adsorb particulate impurities, achieving oil filtration and air purification performance.

















Having driven the V260L for three years, I've replaced the cabin air filter twice myself—it's located behind the glove compartment on the passenger side. Opening the glove box reveals a black plastic cover that pops off with a simple press of the clips. The filter consists of upper and lower layers stacked together; when removing it, remember the direction of the airflow arrow to avoid halving the air volume by installing it backward. Don’t skimp by buying off-brand filters—I tried a cheap one last time, and it started emitting a sour smell within three months, forcing me to spend more on a replacement. Remember to check it before summer; the rainy season can lead to mold buildup, which not only affects health but also strains the AC system.

The mechanic at the repair shop taught me that changing the filter for the V260L is quite simple: lie on the floor on the passenger side, remove the three screws at the bottom of the glove box, and the entire plastic bracket can be taken off. Don't pull too hard; there are connecting wires on the side. The filter slot is above the blower. Use a T20 screwdriver to loosen the cover, and you can pull out the two-layer filter screen, which can have a layer of dust as thick as a finger. It's recommended to change it every six months, especially in northern areas with heavy sand and dust, as clogging can slow down cooling and increase fuel consumption. Doing it yourself saves about 300 yuan compared to doing it at a 4S shop.

The air filter design of the V260L is too hidden! It's located deep inside the front passenger footwell, requiring the removal of the storage compartment floor panel to access it. Why didn't the manufacturer place it in the engine bay? The maintenance manual states it's to avoid the impact of engine heat on filtration efficiency. The dual-layer activated carbon filter can block PM2.5, but it becomes ineffective if clogged with leaves. During the last maintenance, a mouse nest was found on the filter, and two wires were chewed through, so it's important to avoid parking near garbage piles.

Compared to the old Viano, the V260L's air conditioning system has undergone significant upgrades. The filter location has been moved to the rear of the firewall. Although replacing it requires removing over a dozen clips, the sealing performance is better. The genuine German OEM filter comes with an electrostatic adsorption layer, filtering 20% more pollen than standard filters. I've developed a little trick: spraying lemon essential oil on the old filter before reinstalling it works well for temporary odor removal. However, frequent replacement is still necessary in the long run, especially for people with allergies.

The car detailing shop owner shared a tip with me: Turn on the internal circulation for five minutes before replacing the filter to let the blower expel large particles before operation. The V260L filter slot has a drainage design, but it can still accumulate water and mold during the rainy season. Once, a customer's car had a severe odor, and upon disassembly, we found three centimeters of water accumulated under the filter—it turned out the sunroof drain pipe was clogged, causing backflow. So, air conditioning odors aren't always due to the filter; the entire ventilation system needs to be checked.
