Why is my Vauxhall Zafira displaying a 'Check Engine' light?

I noticed that my Vauxhall Zafira's 'Check Engine' light has turned on. What could be causing this and how should I address it?

The 'Check Engine' light could indicate a variety of issues, ranging from a loose gas cap to a faulty oxygen sensor. It's best to take your car to a mechanic to run a diagnostic test and identify the specific problem.

Make sure to check your Zafira's engine oil level and top it up if necessary. Low engine oil can trigger the 'Check Engine' light.

In some cases, a loose or damaged gas cap can cause the 'Check Engine' light to turn on. Try tightening or replacing the gas cap and see if the light turns off.
