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

My Vauxhall Insignia's check engine light is on and I'm not sure what to do. It's been on for a few days now and I'm worried that there might be something wrong with the car. Any suggestions on what I should do?

First of all, don't panic. The check engine light can come on for a variety of reasons, some of which may not be serious. The best thing to do is to take your car to a trusted mechanic and have them run a diagnostic test. This will give you a better understanding of the issue and how to proceed.

If the check engine light is solid and not blinking, it could be a minor issue such as a loose gas cap. Try tightening the cap and see if the light goes off after a few trips. If the light continues to stay on, it's best to get it checked out by a professional.

It's always a good idea to address the check engine light as soon as possible, as it could indicate a larger problem that could become more expensive to fix if left unattended. In the meantime, avoid driving the car too hard or for long distances until the issue is resolved.
