We will therefore begin with a trunk noise on your Citroen C4 Aircross caused by dirt accumulated on your joints, lock for example. Indeed, it is plausible that on a vehicle that is already a few years old and whose cleaning is not always a top priority or that the roads used are not very clean that dirt collects at the trunk gasket. This problem triggers a poor closure of the trunk and a noise that can sound like a crack. To verify if you are in this situation, open the trunk of your Citroen C4 Aircross, examine the state of the gasket that goes around the entire tailgate and clean it with a wet/soap cloth, dry the whole thing and try to close the trunk and take a dentred road to see the difference. If this is not the case, continue to the other hypotheses that will probably give a solution. It is plausible however that you have a trunk noise on your Citroen C4 Aircross that is related to other sources such as shock absorbers, do not hesitate to consult this article on the noises at the back of a Citroen C4 Aircross.

Second probability, you may also, over time, experience a locking system that became loose. And this is one of the most probably alternatives. Indeed, knowing a trunk noise on your Citroen C4 Aircross is very often related to this problem. Different solutions are available to you subject to the level of play you have with your lock. The first is that quite often the offset is minimal and a simple greasing of the mechanism with thick grease is good enough to fix the issue. Secondly, it is also plausible that you really have a lot of play on your lock and that each time the trunk “jumps”, in which case you would have to take off the cover that allows access to the lock (inside the trunk). Then, using torx screws, you unscrew the striker attached to the threshold, just push it back a little towards the inside of the trunk and tighten it again. You should verify the centering of the striker in connection with the trunk lock. If after looking at the trunk of your Citroen C4 Aircross closes badly, it means that you have moved it too far, duplicate the operation by pushing the striker less.
Noise in my trunk Citroen C4 Aircross : Rivet following plate change in the trunk/ bumper
Finally, one of the last possibilities. It is that following a license plate change you were unlucky and that a piece of rivet fell backside your plate. Indeed, when a plate replacement is done, to take off the old one the technique used is to drill the existing rivets in order to put out the license plate. Unfortunately, it can happen that part of the rivet falls into the hole of the bumper and it will therefore wander inside the bumper and can cause an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Citroen C4 Aircross linked to a rivet, you will need to verify that it is in the tailgate open it and stir it to specify the noise. If this is your case, you will have to remove the linings from the trunk to remove it. Finally, if it is your bumper, it is in this rarer and more disturbing case, you will have to take off the bumper to remove the bits of rivet that are running around.
