How to change the diesel filter on Citroen Berlingo II

Let's see how to change the diesel filter on a Citroen Berlingo II; to reach the filter we will have to remove some elements. Let's start by removing the cover of the monoblock, the air intake duct of the turbo, starting with loosening the two closing rings, then removing the clamp that tightens the tube in half and then removing it by releasing the tab that connects it on the other side. To remove the airflow meter, we will have to remove three screws and a connector. We will also remove the upper air intake duct, disconnecting it in two parts: below we can see the diesel filter, from which we will disconnect the electrical connector, then detach the two filter tubes; in the top left we will find a support tab and the water sensor, which we will pull up to release the filter. The diesel filter has a part that is not replaced, and must be recovered from the old one. We can find the piece for example on Amazon with the code B09NC5CJSM at the price of 48.84 euros, free delivery for Prime customers. Let's change the gaskets by greasing them well, then put the piece back into the new filter and wedge it into place, reconnecting the water sensor and the electrical connector, putting the tubes back in place, the air intake duct, the airflow meter with its connector, the turbo feed duct and the monoblock cover.
