How often should the fuel filter of Volkswagen Passat be replaced?

The fuel filter of Volkswagen Passat should be replaced every 15,000 KM or 24 months. Below is some additional information about the fuel filter: 1. The main function of the fuel filter is to remove impurities from gasoline. It is a consumable item and needs to be replaced in a timely manner. 2. The role of the fuel filter is to filter out solid impurities such as iron oxide and dust, or water contained in the gasoline. On one hand, this reduces the likelihood of the fuel injector being clogged by impurities, and on the other hand, it ensures the quality of the gasoline flowing into the fuel system. 3. The filter element of the fuel filter is mostly made of filter paper, but some use nylon cloth or polymer materials. The main function of the fuel filter is to remove impurities from gasoline. When the engine is running, the fuel, under the action of the fuel pump, enters the sediment bowl of the filter through the inlet pipe.
I've got experience with fuel filters. For a Passat, it's best to change it every 30,000 kilometers or so. Last week I just changed mine, and when I took it out, it was full of black impurities—no wonder the acceleration felt sluggish recently. If you drive in dusty areas, like near construction sites or during frequent sandstorms in the north, you might need to replace it as early as 20,000 kilometers. If you don't change it on time, the fuel pump has to work harder, and over time, it could burn out. When replacing it, pay attention to the model number—don't trust those cheap aftermarket parts. I learned this the hard way—mine started leaking after just two months, and I ended up buying an OEM part anyway.
