How to Replace the Diesel Filter on a Citroen C4?

Model: Citroen C4 MK 2 - Years 2010-2018
Part: Diesel fuel filter

How do you change the diesel filter on a Citroen C4? First, open the bonnet and remove the engine cover, the air intake duct, and the mass airflow sensor from its connector. You will then reach the diesel filter, from which you need to disconnect both the electrical connector and the diesel pipes. Press the tab on the top left to release the diesel filter and also detach it from the water sensor. Remove the old filter from the non-replaceable side and replace the old seals with new ones. Attach the new filter and reassemble everything by following the same procedure in reverse order.
