Understanding Code 24: A Common Vauxhall Astra Issue
The appearance of “Code 24” on a Vauxhall Astra’s dashboard can be a perplexing experience for many owners. This diagnostic trouble code (DTC) is often associated with specific electrical malfunctions, particularly those related to lighting systems. While it might seem daunting, understanding the root cause can help you address the issue efficiently.
What Does Code 24 Actually Mean?
In the context of Vauxhall Astra models, Code 24 typically indicates a problem with the vehicle’s number plate lights. This could be due to a burnt-out bulb, a faulty wiring harness, or even a more complex electrical issue. It’s essential to diagnose the exact problem accurately to ensure a lasting solution.
Common Causes of Code 24
Several factors can trigger the appearance of Code 24 on your Vauxhall Astra’s dashboard. Let’s explore the most common culprits:
Burnt-Out Number Plate Bulbs
This is the most straightforward explanation for Code 24. Over time, the filaments in number plate bulbs can burn out, leading to the error code. Replacing the faulty bulb(s) is usually a quick and inexpensive fix.
Defective Number Plate Light Wiring
If both number plate lights are out, the issue might lie in the wiring harness. Check for any visible damage, loose connections, or corrosion in the wiring leading to the lights. Repairing or replacing damaged wiring is essential.
Control Module Malfunction
In some cases, the vehicle’s control module might be misinterpreting data, leading to a false Code 24. While less common, it’s worth considering if other electrical systems are experiencing issues.
Grounding Problems
Poor grounding can affect various electrical components, including the number plate lights. Check the ground connection for the lighting system and ensure it’s clean and tight.

To effectively diagnose and resolve Code 24, follow these steps:
Visual Inspection:
- Examine the number plate lights for visible damage or burnt-out bulbs.
