How often should the air filter of Volkswagen Polo be replaced?

[LaEmilia]

According to the vehicle's maintenance manual, the air filter of Volkswagen Polo should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The position of the car's air filter element is determined by the intake form and the structure of the engine. It is usually located in the air filter on the engine intake pipe. There are two types of air filters in cars: dry and wet. The dry type is made of paper or organic materials, while the wet type is made of metal wire mesh. Function of the air filter: It filters out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder and preventing floating dust in the air from being sucked into the engine, which accelerates the wear of the piston group and the cylinder. Air filter: Also known as air filter cartridge, air cleaner, or style. It is a device that removes particulate impurities from the air. When the engine is running, it needs to suck in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand in the air, ensuring that sufficient and clean air enters the cylinder. A dirty air cleaner: Using a dirty air cleaner while driving will cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the car must keep the air cleaner clean. The car air cleaner is a device that removes particulate impurities from the air, consisting of one or several air filter components. Its main function is to filter out harmful impurities in the air that is about to enter the cylinder, to reduce early wear of the cylinder, piston, piston ring, valve, and valve seat. Therefore, before the air enters the cylinder, it must first pass through the fine filtration of the air cleaner. A dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When checking the air cleaner, if it is found to have little dust and is lightly clogged, it can be cleaned with high-pressure air from the inside out and continue to be used. A severely dirty air cleaner should be replaced in time. Volkswagen Polo air filter cleaning method: Preferably use an air gun to blow, or you can also use a household hair dryer. Due to the structure of the filter, blow from the intake side first, then from the inside out, and finally gently tap the surface of the air filter. Never use water to clean it, otherwise, you will have to replace it.
