Why is my Vauxhall Insignia's engine light on?

I recently noticed that the engine light on my Vauxhall Insignia has come on. I'm not sure why this is happening and I'm concerned about potential damage or issues with the car. What could be the cause of this and what should I do?

It's possible that the engine light is indicating a malfunction in your car's emissions system. This could be caused by a variety of issues such as a faulty oxygen sensor or a loose gas cap. It's important to have this checked by a mechanic as soon as possible to avoid any potential damage to your engine.

Your car's engine light could also come on due to a misfire in the engine. This could be caused by worn spark plugs or a clogged fuel filter. I would suggest bringing your car to a trusted mechanic to have it properly diagnosed and repaired.

In some cases, the engine light can also indicate a more serious issue such as a failing catalytic converter. If this is the case, it's important to have it replaced as soon as possible to avoid further damage and to ensure your car passes emissions tests.
