Double-check your vehicle's exact model, year, and engine code (OM651.950 for 2.2D). Use online compatibility checkers or contact customer support with your VIN.

Setup, Compatibility & Care

Compatibility Verification: Before installation, always confirm that the Mahle KL950 fuel filter is compatible with your specific Mercedes-Benz V220 CDI W447 or Vito W447 model, engine type (2.2D OM651.950), and production year (2014 onwards). Use the vehicle compatibility tool or consult your vehicle's documentation.

Installation: This is a component of the vehicle's fuel system and should be installed by a qualified mechanic. The process typically involves safely relieving fuel pressure, disconnecting the fuel lines from the old filter, removing the filter housing, replacing the filter element, and reconnecting lines. Ensure all connections are secure to prevent fuel leaks.

Water Sensor: Note that this filter does not have a port for a water sensor. If your original filter had one, you will need to address this during installation, potentially by retaining the old sensor if it's separate from the filter housing or consulting a professional for a solution.

Care: Fuel filters are designed for single-use replacement. Once removed, they cannot be cleaned or reused. Regular replacement according to your vehicle manufacturer's recommended service intervals is essential for proper engine care and longevity.
