What causes the 'Engine Malfunction' warning light to come on in my Vauxhall Insignia?

I recently noticed the 'Engine Malfunction' warning light has come on in my Vauxhall Insignia. What could be causing this and how can I fix it?

The 'Engine Malfunction' warning light could come on for a variety of reasons, such as a faulty sensor, a loose gas cap, or a problem with the ignition system. It's best to bring your car to a mechanic for a diagnostic test to determine the exact cause.

If your gas cap isn't tightly closed, it can cause the 'Engine Malfunction' warning light to come on. Make sure to tighten the cap until it clicks to see if that resolves the issue.

If the problem is with the ignition system, you may notice other symptoms such as a rough idle or difficulty starting the car. In this case, it's important to get it fixed as soon as possible to avoid further damage to your engine.
