In fact, it is plausible that on a car 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 causes a poor closure of the trunk and a noise that can sound like a crack. To examine if you are in this circumstance, open the trunk of your Citroen C-crosser, check 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 impact.

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 strip off the cover that allows access to the lock (inside the trunk). Then, using torx screws, you unscrew the striker attached to the threshold, simply push it back a little towards the inside of the trunk and tighten it again. Don’t forget to examine the centering of the striker in relation to the trunk lock.
