Why is my Vauxhall Mokka's engine light on?

My Vauxhall Mokka's engine light has been on for the past few days. Is this something I should be worried about?

It is important to get your car checked as soon as possible when the engine light is on. This could be an indication of a serious issue.

Check your gas cap. Sometimes a loose gas cap can trigger the engine light to come on. If it is not tightened properly, the light should turn off after a few driving cycles.

It could be a minor issue, such as a faulty sensor. However, it is always better to get it checked by a professional mechanic to avoid any potential problems.
