You'll need a thin screwdriver, preferably "sentry", to remove the cap of the Peugeot 207. To remove the cap, lift the lid of the boot to the eye level. Then gently insert the screwdriver into one of the holes located on the sides. If you don't make a big effort, put the cap on and pull it out. If the process is still broken, the original order number is 6340.A3.
