i remember before in the past that a couple of people who have flushed the doors handles n such still have a keyhole thing on the flap of the fuel filler thing. (they complain its too expensive to flush n have a mechanism fitted) its so simple to add the catch mechanism to release the boot n filler cap i did it to mine yesterday (took off a old model which had the mechanism) then 2 remove the filler cap is just some screws then replace with new one that doesnt have a key hole...only hassle was the mounting of the "handle" to release the boot/filler flap as there wasnt a hole on the right sil of the driver side just a indented grove where its meant to go just knock that through drill 2 holes for screws n ur done...
