Why is my Vauxhall Grandland's check engine light constantly on?

I recently noticed that the check engine light on my Vauxhall Grandland has been staying on for longer periods of time. What could be causing this and how can I fix it?

There could be multiple reasons why your check engine light is staying on. One possible cause could be a faulty oxygen sensor. I recommend taking your car to a certified mechanic to properly diagnose and fix the issue.

Another possible reason for the check engine light staying on could be a loose or damaged gas cap. Try checking and tightening your gas cap first before seeking further assistance.

If the check engine light is accompanied by other symptoms such as unusual noises or poor engine performance, it could be a sign of a more serious issue. In this case, it's best to have a professional take a look at your car.
