Routine maintenance items for the Passat: Oil change: Engine oil is the lubricating oil for engine operation. It serves functions such as lubrication, cleaning, cooling, sealing, and wear reduction for the engine. It plays a significant role in reducing wear on engine components and extending their service life. You can determine whether the oil needs to be changed by observing if the viscosity of the oil has changed, if the smell of the oil has faded, or if the color of the oil has altered. Oil filter replacement: The oil filter is the component that filters the engine oil. Engine oil contains a certain amount of gum, impurities, water, and additives. During engine operation, metal shavings generated by friction between components, impurities inhaled from the air, and oil oxides are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circuit, it will adversely affect the performance and lifespan of the engine. Air filter replacement: During operation, the engine inhales a large amount of air. If the air is not filtered, the dust in it can accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder can also cause severe cylinder scoring. The role of the air filter is to remove dust and particles from the air, ensuring that sufficient and clean air enters the cylinder.
