Video tutorial

We can see how it is possible to change the additive tank of the FAP on the Citroen C4 Aircross: by lifting the car, on the rear axle we can see a black box. It is not in an easy position, the car must be well lifted to reach it, and the tank is fixed against the frame.

We will have to remove the bolts that hold it fixed to the frame, disconnect the electrical connectors on one side, and the fluid delivery tubes.

We can find the new tank for example on Amazon with the code B0B5VZ4425 at a price of 128.28 euros + delivery costs of 16.60 euros. We replace the inside of the tank and then put the box back where we found it. It is not an easy DIY job to do but with a little patience we can succeed.
