we've just purchased a 2004 Megane 2 cab, 1.9 dci Privalidge and it has a number of very small problems (we got it cheap to reflect these).
One of them, i'm not sure is a problem or not.....
There doesn't seem to be a petrol cap as such or locking mechanism, just a metal plate you force the hose nosel through which then flaps back after filling. It strikes me that this might not be normal and maybe the exterior (thats the same cover as the body paint) cover should lock? I've looked at it but can't honestly see a locking mechanism on it. If this is the case, i'm also unable to find a button to release the exterior flap!?
Of course, it could be designed like this and it could have protection built deep down in it to stop someone sticking a tube down and sucking up diesel!

Is it a problem or is it correct?

edit: Sorry, also, should the privalidge have had reverse parking sensors? For some reason I think it should have but we don't appear to.
Many thanks!!!
