How do I troubleshoot a flashing engine light in my Vauxhall Zafira Life?

My Vauxhall Zafira Life has a flashing engine light, what can I do to troubleshoot and fix this issue?

First, check your gas cap to make sure it is tightly sealed. If it is loose, tighten it and see if the light stops flashing. If not, you may need to replace the gas cap.

If the gas cap is not the issue, the next step would be to check the spark plugs. Worn out or faulty spark plugs can cause the engine light to flash. If needed, replace the spark plugs.

Another possible cause of the flashing engine light could be a faulty oxygen sensor. A mechanic can run a diagnostic to determine if this is the issue and replace the sensor if needed.

In some cases, a dirty air filter can also cause the engine light to flash. It's a good idea to regularly check and replace your air filter to prevent any issues.
