Model: Audi A6 MK 3, C6 - Years 2004-2012
Part: Diesel fuel filter

Need to replace the fuel filter on an Audi A6? Let's see how to remove it from the engine compartment. Use a screwdriver to unscrew the screws that secure the clamps (you can also use a socket wrench) around the circulation hoses above the container where the fuel filter is located. Once the filter is removed, take it out of the vehicle (replace it with a new filter). Finally, reinstall the filter into the fuel filter container, connect the hoses and wires, and tighten the screws on the clamps. Close the hood, start the car, and test for proper operation.
