General Fiat 500 petrol cap problems

[Ruthiek17]

This is my second 500 which I love except for one thing - the petrol cap ! It’s a nightmare to lock and unlock, I do it the same every time but sometimes it opens other times it won’t , I have been known to drive out of a petrol station as I cant get it unlocked !

Never had an issue, hold the cap, turn the key, twist the cap off. Which part doesn't work for you?
