I will have a look, thank you.
What about trying https://www.partsgateway.co.uk/m/
I'm still looking for one on ebay. They have several for say the Citroen C3, C4 ,etc, at reasonable prices. There were a couple for the Citroen Xsarra Picasso but for around £45 which is not what I really want to pay to be honest, especially as they were red, etc (my car is grey), so the cost of spraying it would be on top. My local scrap yard has now closed and the next nearest one doesn't have one, but I will keep looking. It's a bit frustrating really as the cover is fine, it's the hinge etc that has broken away. Currently got the cover taped to the side of the car with black tape which obviously is a bit inconvenient when I go to fill up the car, also I'm avoiding car washes at the moment because of it. Thank you.
Did you get the petrol flap sorted?
Easy enough. When fitting there is almost always aome sort of lug to ensure the alignment is good. It isn't always obvious although on your pic of the wheel without the centre you can see there is a cut-out at the top that the locating lugs on the centre will fit into. Its easy to break the locating lugs by trying to force fit with the wrong orientation. usually jest needs a sharp thump to fit them - need to compress the sprung ring
