There is definately a Citroen Inforapid bulletin on the fuel flap problem on C4 Picassos. As far as I recall the problem is with the pin that releases the flap not moving back and forwards as normal.

As I have tanked the car at 4 different petrol station since this problem occured, that's why I have disqualified the petrol problem.
