It is getting harder to change a bulb with every new model, with less and less room. If you have the owners book have a look there first. Here are the pictures of how to fit a Skoda Octavia headlight bulb, easy when you know how.
1. First remove the plastic nut.
2. Then pull the lever hard towards centre of car.
3. The headlight will then come out.
4. Release the two cover retaining clips and you can then get to the bulb
