How do I troubleshoot my Vauxhall Crossland's engine warning light?

I recently noticed that the engine warning light on my Vauxhall Crossland has turned on. What could be the potential causes and how can I address this issue?

One of the possible causes of the engine warning light is a loose or faulty gas cap. Check if the gas cap is securely fastened and try tightening it. If the light persists, it may indicate a more serious issue and it's recommended to have it checked by a certified mechanic.

Another potential cause is a malfunctioning oxygen sensor. This can lead to a decrease in fuel efficiency and increased emissions. It's important to have it replaced as soon as possible to avoid further damage to the engine.

A clogged or dirty air filter can also trigger the engine warning light. Regularly checking and replacing the air filter can improve the overall performance of your vehicle.
