BMW 1 Series F40 116d Fuel Filter

BOSCH F 026 402 257 | Common Rail Protection

The original BOSCH (F 026 402 257) fuel filter is designed for the 2019 and later models of the new body of the BMW 1 Series (F40) 116d with the B37 (1.5 Litre 3 Cylinder Diesel) engine. It protects the high-pressure "Common Rail" diesel injection system from water, rust, sediment, and microscopic particles, preventing injector failures and performance losses.

  • Bosch Quality: Manufactured by Bosch, the inventor of diesel injection systems, it maintains your vehicle's factory standards.
  • Water Separation: Separates over 95% of the water in the fuel, preventing rust and irregular engine operation.
  • High Durability: Thanks to its multi-layer filter paper, it makes it difficult for fuel to freeze even in harsh winter conditions and ensures fluidity.
  • F40 Body Compatibility: Specifically sized for diesel engines on BMW's new generation front-wheel-drive platform.

Frequently Asked Questions (FAQ)

Does this filter fit the 118i (Petrol) vehicle? No, it does not fit. This product is a diesel fuel filter. In petrol vehicles like the 118i, the fuel filter is located inside the tank and is not replaced as a maintenance part in this way. It is only for 116d diesel models.
Does it come with a heater? No. The black plastic part on the filter (fuel heater) is the vehicle's own part and is reused. During installation, you need to remove the heater from your old filter and install it on this new Bosch filter, renewing the gasket set (if applicable).
How often should I replace it? For BMW diesel vehicles, considering the fuel quality in our country, it is recommended to replace it every 2 maintenance intervals (approximately 30,000 km) for the health of the injectors.
What other vehicles does it fit? This filter is also fully compatible with; BMW 2 Series Gran Coupe (F44) 216d, X1 (F48) 16d/18d, X2 (F39), and the new generation MINI Cooper D (F56) models.
