- Engage the parking brake and put the vehicle in park.
- Allow the engine to cool down completely.
- Wear safety glasses and gloves for protection.
Tools and Materials: Gather What You Need
To successfully change the fuel filter, you’ll require the following tools and materials:
- New fuel filter (refer to your BMW 1 Series owner’s manual for the correct part number)
- Fuel filter wrench or pliers
- 10mm socket wrench or spanner
- Fuel filter housing wrench (optional, but recommended)
- Clean rags or paper towels
- Fuel system cleaner (optional)
Step 1: Locate the Fuel Filter
Open the hood and locate the fuel filter housing. It’s typically situated near the engine, close to the firewall. The housing is usually black or gray in color and has two fuel lines connected to it.
Step 2: Disconnect the Fuel Lines
Using the fuel filter wrench or pliers, carefully loosen the fuel line clamps. Gently pull the fuel lines off the filter housing. Be prepared for a small amount of fuel spillage.
Step 3: Remove the Old Fuel Filter
Use the 10mm socket wrench or spanner to loosen the fuel filter housing cap. Carefully remove the old fuel filter from the housing. Inspect the filter for any signs of contamination or damage.
Step 4: Clean the Fuel Filter Housing
Using clean rags or paper towels, thoroughly clean the inside of the fuel filter housing to remove any debris or old fuel residue.
Step 5: Install the New Fuel Filter
Insert the new fuel filter into the housing, ensuring the arrows on the filter align with the flow of fuel. Tighten the fuel filter housing cap using the 10mm socket wrench or spanner.
Step 6: Reconnect the Fuel Lines
Reattach the fuel lines to the filter housing and tighten the fuel line clamps using the fuel filter wrench or pliers.
Step 7: Prime the Fuel System
With the fuel lines reconnected, turn the ignition key to the “on” position without starting the engine. This will prime the fuel system by pumping fuel through the new filter. Repeat this step a few times until the fuel pressure stabilizes.
Start the Engine and Check for Leaks
Start the engine and let it idle for a few minutes. Check for any fuel leaks around the fuel filter housing and fuel lines. If you notice any leaks, tighten the connections further.
Optional: Use Fuel System Cleaner
For optimal fuel system performance, you can add fuel system cleaner to your fuel tank. Follow the instructions on the cleaner package for proper usage.
Wrapping Up: A Job Well Done
Congratulations! You have successfully changed the fuel filter in your BMW 1 Series. By following these steps, you’ve ensured the optimal flow of clean fuel to your engine, improving its performance and longevity.
