2018 Vauxhall Astra fuse box location & diagram

This car has 4 fuse boxes.

  • UK specification
  • Verified data
  • Checked 15 October 2026
  • Sources

Partly covered: Vauxhall published August 2017, January 2018, March 2018 and August 2018 Astra handbooks that could apply to a 2018 car, and their fuse charts differ. Vauxhall doesn’t say which cars each edition applies to, so we can’t tell which one matches a particular 2018 Astra. Every official chart is shown below — check the edition printed near the end of your handbook, or compare with the fuse box legend in your car, before removing anything.

Which 2018 Astra do you have?

The fuse layout differs between versions of the 2018 Vauxhall Astra. Until you choose, the chart for every version is shown.

Not sure which handbook edition you have?
  • Each Vauxhall owner’s manual prints its edition near the end, for example “Edition: September 2014”. If you have your car’s handbook, choose the option with the same edition.
  • Vauxhall doesn’t say which cars each edition applies to, so the date of your car alone can’t tell you. Without the handbook, compare the circuits on each option with the legend on your fuse box before removing anything.

If you can’t confirm it, keep both results in mind and check the fuse box legend before removing anything.

Fuses near the vehicle battery

How to get to it

Additional fuses are located near the vehicle battery.

Our source doesn’t describe how to open this fuse box. Check your owner’s handbook.

Find it by its handbook number

Vauxhall’s handbook lists these as fuses near the vehicle battery, separate from the fuse boxes. Its picture of them doesn’t give enough positional detail for a trustworthy map, so we don’t draw one.

Use the fuse numbers and the picture of this area in your owner’s manual to identify each fuse, and check it against the handbook before removing anything.

Tools that may help

  • Fuse assortment kit

    Spare blade fuses in common ratings, so you can swap a blown one at the roadside.

  • Fuse puller

    Grips small fuses without damaging them. Many fuse boxes have one clipped inside the lid.

  • Digital multimeter

    Confirms whether a fuse or socket actually has power, instead of guessing.
