How to Remove the Front Bumper of the Citroën C4 Picasso?

To remove the front bumper of the Citroën C4 Picasso, you need to take out all the rivets and screws that secure the piece to its housing: these screws are located inside the wheel arches of the front wheels and at the central upper part of the bumper itself. Once all these fastening elements have been removed, you can detach the bumper from its seat by disconnecting the connectors inside and then insert the new replacement part. The new part can then be secured and connected properly, ensuring it is correctly fixed in place.
