J´ai eu le même problème, j´ai fini par utiliser le "Marvin-Mode".
Marvin-Mode
To activate the real cheats, and the console,
you need to activate the marvin mode.
Enter your Status screen (B par défaut) (character screen) so you can see your
skills & attributes.
On the keyboard, type "marvin". (Sur un clavier azerty : ,qrvin)
Exit your Status Screen again, and make sure "marvin-mode" is written in
the top left corner.
Now you have activated the Marvin-Mode and the Console.
This make hundreds of options open to you.
K Teleport the character forward (very useful)
(téléporte le personnage de quelques mètres vers l´avant, ça permet de passer le trou)
