How to Open the Fuel Filler Flap, When Stuck, on a Peugeot 407

Model: Peugeot 407 MK 1 - Years 2004-2012
Part: Fuel cap

When the fuel filler flap gets stuck on a Peugeot 407, first check if the relevant fuse needs replacing. To do this, open the boot and, on the left (as shown in the images), locate the fuse box. The fuse of interest is the second one (also indicated in the images). If the problem is not the fuse, proceed to remove the rubber under the flap. After this, remove the inner/upper liner of the wheel arch by unscrewing the indicated screws with the appropriate tools. Once this is done, you will have access to the electric opening mechanism of the fuel flap. Simply lower the plunger (as shown in the video) and you're done.
