Why is my Vauxhall Corsa's check engine light blinking?

I recently bought a used Vauxhall Corsa and the check engine light has started blinking. What could be the cause and what should I do?

A blinking check engine light typically indicates a more serious issue than a solid light. It could be due to a faulty oxygen sensor, catalytic converter, or spark plugs. It's best to take your car to a mechanic to diagnose the exact issue.

I had the same issue with my Corsa and it turned out to be a loose gas cap. Make sure to check this first before taking it to a mechanic.

I recommend getting a diagnostic tool to read the error codes from your car's computer. This will give you a better idea of what the issue could be.
