Why is my Vauxhall Grandland's engine light on?

I've noticed that the engine light on my Vauxhall Grandland has turned on. What could be causing this and how can I fix it?

The engine light can come on due to a variety of reasons, such as a loose gas cap, a faulty sensor, or a serious engine issue. It's important to take your car to a certified mechanic as soon as possible to get it properly diagnosed and fixed.

One common reason for the engine light to turn on is a misfiring spark plug. It's recommended to check and replace your spark plugs every 30,000 miles. If you're not comfortable doing it yourself, take your car to a professional.

The engine light can also indicate a problem with your catalytic converter, which is responsible for reducing harmful emissions. It's important to get this issue fixed as it can lead to more serious problems with your car.
