Corsa fuel flap release malfunction

I had a similar issue with my Renault Megane. The fuel filler door wouldn't open. Does the Corsa use an electric actuator or a cable release? In my case, the electric actuator had failed.

Thanks. I'm not entirely sure about the release mechanism, but I suspect it might be an electric actuator. Is there a way to be sure?

Well, on my Megane, the actuator was the culprit. Given your symptoms and the error message, it's likely the same for you. I'd suggest taking it to a workshop to get it diagnosed properly. If it is the actuator, replacement should fix it.

Thanks! I took the Corsa to a workshop for a diagnosis. Apparently it was the lock actuator linkage defective which caused the issue. The total repair cost was 210€.
