the other day opened the flap covering the petrol filler pipe and heard a funny snap sound. the flap felt funny and kinda loose.

Before the flap used to close with some spring force but now it feels like its about to fall off.

Just wondering is there a spring that is part of the flap?

Took out the plastic bits in the boot so could look behind the petrol filler for a spring or something but didnt find one.

The car is a corsa BTW =) can anyone help?
