  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Gather necessary tools and parts.

  2. Inspect the Fuel Cap

    • Examine the cap for any cracks, dents, or broken components. Check the gasket for integrity.

  3. Replace the Fuel Cap if Damaged

    • If damage is found, purchase a replacement cap that is compatible with the Skoda Octavia.
