What is the cause of the engine warning light on my Vauxhall Mokka?

I recently noticed that the engine warning light has appeared on my Vauxhall Mokka dashboard. What could be the potential cause and how can I fix it?

The engine warning light can indicate a multitude of issues, ranging from a loose gas cap to a more serious engine malfunction. It's important to get your car checked by a professional mechanic as soon as possible.

Based on my experience with my Vauxhall Mokka, the engine warning light can be triggered by a faulty oxygen sensor. This can easily be fixed by replacing the sensor.

I had a similar experience with my Vauxhall Mokka and it turned out to be a faulty catalytic converter. It's best to get it checked and replaced if necessary to prevent further damage.
