Just brought my seat Toledo 1.9 tdi 110. The thing is i think i'm missing something from the petrol cap to make it open from inside the car. The flap can just be opened my pulling it from the outside and the buttom doesn't do anything. Because i haven't had one of these before i don't know what it should look like when you open the fuel flap, should there be a wire coming out or something like that to keep the flap shut. All i have there is what looks like a metal clip.
