Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
If applicable, disconnect the battery to prevent any electrical issues while working.

2. Apply Lubrication

Tools Required: Penetrating oil or silicone spray, cloth.
Spray a small amount of penetrating oil or silicone spray around the gas cap's threads and the filler neck.
Allow the lubricant to sit for a few minutes to penetrate any corrosion or debris.

If it still does not budge, gently tap the gas cap with a rubber mallet to dislodge any stuck components.

4. Remove the Gas Cap

If the cap is still stuck, use a pair of pliers wrapped in a cloth to avoid scratching it.
Carefully grip the gas cap and turn counterclockwise, applying steady pressure.

5. Inspect and Clean

Once removed, inspect the gas cap and fuel filler neck for any damage, debris, or corrosion.
Clean the threads of the gas cap and the filler neck using a cloth.

If the gas cap is damaged, replace it with a new part specific to the Skoda Octavia NFL.
If the cap is in good condition, reinstall it by aligning the threads and turning it clockwise until it clicks securely.
