🔧 Beetle - Fuel Cap Replacement

Follow these steps in order:

Step 1: Remove the old fuel cap

Step 2: Inspect the filler neck

• Look at the sealing surface on the fuel filler neck for dirt, cracks, or damage.
• Wipe it clean with a dry cloth if needed.
• Make sure nothing is stuck in the opening.

Step 3: Install the new fuel cap

• Place the new cap on the filler neck and turn it clockwise by hand.
• Tighten until it clicks several times or seats fully, depending on cap design.
• Do not use tools; hand-tight only.

Step 4: Confirm proper fit

• Gently tug on the cap to confirm it is locked in place.
• Close the fuel door.
• If the check engine light was on for an EVAP cap fault, it may clear after several drive cycles.
