how to replace the fuel filter in my BMW 5 Series G30/G31 (2017-2024)

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Remove the Fuel Filter

• Locate the Fuel Filter: Find the fuel filter, which is typically located along the fuel line under the vehicle.
• Disconnect Fuel Lines: Use a fuel line disconnect tool to detach the inlet and outlet lines from the fuel filter. Have a rag or container ready to catch any fuel that may spill.
• Unbolt the Fuel Filter: Remove any mounting bolts securing the fuel filter to its bracket using a socket set.

3. Install New Fuel Filter

• Position New Filter: Place the new fuel filter in the same orientation as the old one, ensuring the flow direction matches the markings on the filter.
• Secure the Filter: Reinstall the mounting bolts and tighten them to the manufacturer's specified torque (usually around 10-15 Nm).
• Reconnect Fuel Lines: Reattach the fuel lines to the new filter, ensuring they are secured properly.

4. Final Checks

• Reconnect Battery: Reattach the negative battery terminal.
• Check for Leaks: Turn the ignition to the ON position (without starting the engine) to prime the fuel system. Inspect the filter and connections for any signs of fuel leaks.
• Start the Engine: Start the engine and allow it to idle. Monitor for any unusual sounds or leaks.
