What should I do if my Vauxhall Corsa's check engine light is on?

I recently noticed that my Vauxhall Corsa's check engine light has turned on. I'm not sure what could be causing it and if I should be worried. What should I do in this situation?

If your check engine light is on, don't panic! The first thing you should do is check if your fuel cap is tight. A loose or damaged fuel cap is a common reason for the light to turn on. If that doesn't solve the issue, it's best to take your car to a mechanic for a diagnostic check.

I had a similar experience with my Vauxhall Corsa and it turned out to be a faulty oxygen sensor. It's a good idea to address the issue sooner rather than later, as it can lead to reduced fuel efficiency and potentially cause damage to your car's engine.

I've had my check engine light come on before and it was due to a loose gas cap. Make sure to check that first before spending money on a diagnostic check. Also, if you notice any strange noises or a decrease in performance, it's best to get it checked by a professional.
