Troubleshooting the Vauxhall Insignia's Engine Warning Light

I am having an issue with the engine warning light on my Vauxhall Insignia constantly turning on. What could be causing this and what steps can I take to fix it?

First, check the OBD II codes using a diagnostic scanner to determine the specific problem. It could be a faulty sensor or an issue with the emissions system.

Make sure all your gas caps are tightly closed. A loose or missing gas cap can trigger the engine warning light.

Another common cause is a faulty catalytic converter. If you notice a decrease in performance and increased fuel consumption, this could be the issue.

If none of the above solutions work, it's best to take your car to a professional mechanic for further inspection. Ignoring the issue can lead to more serious and costly problems down the line.
