2017-2019 Skoda Octavia Fuse Box Diagram [Mk3/5E]

The Skoda Octavia fuse box diagram is a helpful tool for troubleshooting electrical problems in your car. It shows the location of all the fuses in the fuse box, as well as the amperage rating of each fuse.

If you’re having trouble with a particular electrical component, you can use the fuse box diagram to identify the fuse that protects that component. Once you’ve identified the fuse, you can check to see if it’s blown. If it is, you can replace it with a fuse of the same amperage rating.

Fuse Box Locations

There are two fuse boxes in the Skoda Octavia Mk3/5E models from 2017 to 2019.

  • The passenger compartment fuse box is located behind the storage compartment in the left-hand section of the dash panel.
  • The engine compartment fuse box is located in the engine compartment, on the left-hand side of the car.

Fuses Replacement

To replace a fuse, follow these steps:

  1. Locate the fuse box that contains the blown fuse.
  2. Use a fuse puller to remove the blown fuse.
  3. Inspect the blown fuse to see if it is visibly damaged. If the fuse is visibly damaged, replace it with a fuse of the same amperage rating.
  4. Insert the new fuse into the fuse box.
  5. Close the fuse box cover.

Troubleshooting Electrical Problems

If you are having trouble with a particular electrical component in your Skoda Octavia, you can use the fuse box diagram to help you troubleshoot the problem. Here are some steps you can follow:

  • Identify the fuse that protects the electrical component that is not working.
  • Check the fuse to see if it is blown. If the fuse is blown, replace it with a fuse of the same amperage rating.
  • If the fuse is not blown, the electrical component may be defective. In this case, you will need to take your car to a mechanic to have the electrical component repaired or replaced.
