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

[LeAllie]

The fuel filter of Volkswagen CC must be replaced every 30,000 kilometers under normal usage conditions. Definition of fuel filter: It filters impurities in the vehicle's fuel. Depending on the type of fuel, it can be categorized into gasoline filters and diesel filters. It is a type of wear-and-tear part that requires regular cleaning and replacement. Impact of inferior fuel filters: Poor filtration performance. After prolonged immersion in engine oil, the filter element's filtration layer may detach, blocking the fuel line and causing insufficient fuel pressure, which prevents the vehicle from starting. Additionally, it can lead to abnormal fuel system pressure, directly resulting in insufficient engine power or incomplete combustion, damaging expensive components such as the catalytic converter and oxygen sensors, and causing significant economic losses.
