The fuel filter on the BMW F18 is located on the left side of the transmission. Main functions of the fuel filter: The primary function of the BMW fuel filter is to remove impurities from the gasoline. If the fuel filter becomes excessively dirty or clogged, the main symptoms include: slow or unresponsive acceleration when pressing the gas pedal, difficulty starting the car, and sometimes requiring 2-5 attempts to start the engine. Fuel filter replacement interval: Most engines are equipped with a disposable, non-cleanable paper fuel filter. The replacement interval is generally 10,000 kilometers. If the gasoline used has fewer impurities, replacing it every 15,000-20,000 kilometers is also acceptable. The fuel filter has inlet and outlet arrows marked on it; make sure not to install it backwards during replacement.
