Before starting, open the front bonnet of your Citroen C3. Begin by unfastening and removing the upper engine cover. Next, remove the air filter hoses by simply releasing the fastening clips, then remove the upper battery cover. This will give you access to the diesel filter. Proceed to disconnect the relevant hoses and the electrical connector. At this point, unclip the clip that secures the diesel filter, then remove the filter itself, completing the disassembly.
