What causes the engine light to turn on in a Vauxhall Astra?

I recently noticed that the engine light in my Vauxhall Astra turned on. What could possibly be the cause of this?

The engine light can turn on due to a variety of reasons such as a faulty sensor, low oil pressure, or an issue with the catalytic converter. I would recommend taking your car to a mechanic to get it checked.

It's possible that the gas cap wasn't tightened properly, causing the engine light to turn on. Try tightening it or replacing it if necessary.

Another potential reason for the engine light could be a malfunction in the emission control system. It's best to get this checked by a professional as soon as possible.
