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

According to the vehicle's maintenance manual, the air filter of Volkswagen Lavida generally needs to be replaced every 10,000 to 20,000 kilometers or during every other maintenance. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The location of the car's air filter is determined by the intake form and the structure of the engine. It is usually located in the air cleaner 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. The function of the air filter is to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder, preventing floating dust in the air from being sucked into the engine and accelerating the wear of the piston group and cylinder. Air filter: It is a type of filter, also called an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. During operation, the engine 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 cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially 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 particles in the air, ensuring sufficient and clean air enters the cylinder. Using a dirty air cleaner while driving can 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 components that clean the air. Its main function is to filter out harmful impurities in the air that will enter the cylinder, reducing early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before the air enters the cylinder, it must be finely filtered by 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 by blowing high-pressure air from the inside out and continue to be used. A severely dirty air cleaner should be replaced in time.
As a long-time Volkswagen Lavida owner with over a decade of driving experience, I'm very familiar with air filter replacement. The Volkswagen manual typically recommends changing it every 15,000 kilometers or once a year, depending on your driving environment. In urban areas with heavy traffic and severe air pollution, you might need to replace it earlier, say around 10,000 kilometers. Doing it yourself is quite simple: pop open the hood, locate the air filter box, take it out and check for dust accumulation. If it's dirty and turned black, replace it immediately without delay. I've experienced delayed replacement before – the engine struggled to intake air, causing acceleration difficulties and a fuel consumption spike of over 10%. Not only does this cost more money, but it could also damage the engine. Remember to check it during routine maintenance; the cost is low, just a few dozen yuan for a new filter. Don't overlook this small task – timely maintenance ensures smoother engine operation, extends lifespan, and saves long-term repair costs. Developing good habits makes your car more durable and gives you peace of mind while driving.
