How to troubleshoot a check engine light in a Vauxhall Grandland?

I have a 2019 Vauxhall Grandland and the check engine light recently came on. What could be causing this and how can I fix it?

The check engine light can indicate a variety of issues, from a loose gas cap to a more serious engine problem. It's important to get it checked out by a mechanic to properly diagnose the issue.

Some potential causes for the check engine light could be a faulty oxygen sensor, a bad spark plug, or a malfunctioning catalytic converter. It's best to bring it to a trusted mechanic to get a proper diagnosis.

One thing you can try before taking it to a mechanic is to check if your gas cap is properly tightened. A loose gas cap can cause the check engine light to come on. If that doesn't solve the issue, it's best to bring it in for a check-up.
