What is the cause of the Vauxhall Vivaro's check engine light?

My Vauxhall Vivaro's check engine light keeps turning on. How can I determine the cause of this issue and fix it?

It could be a simple issue like a loose gas cap, but it's best to have a diagnostic scan done to identify the specific problem.

An error code can be helpful in pinpointing the issue. Consider investing in a reliable scan tool or take your vehicle to a trusted mechanic.

If the light is blinking, it could signal a serious problem. It's important to stop driving and seek professional help immediately.
