What Does the Check Engine light Mean on a Vauxhall Astra?

I recently had the check engine light turn on in my Vauxhall Astra and I'm wondering what it signifies. Can you explain what could be causing it?

The check engine light can indicate a variety of issues with your Vauxhall Astra, from minor problems to more serious ones. It's important to get it checked out by a mechanic as soon as possible to prevent any further damage to your vehicle.

The first step is to check the most common cause of the check engine light, which is a loose or faulty gas cap. This can be easily fixed by tightening the cap or replacing it if needed.

If the gas cap is not the issue, it could be a problem with the engine, emissions system, or other components. It's best to have a professional diagnose the issue to prevent any potential hazards.
