If you detect a noise on your car, you are right to be aware of it and take it seriously, although it is plausible that nothing critical will occur, it is also plausible that it is the indication of a more significant repair. A noise that happens in the trunk of your Citroen C3 is thankfully more a sign of a small adjustment or restoration, rather than a complex one. To help you in your research, we have decided to produce this content page to present you with the most likely solutions to your trouble. First we will see that this trunk noise on your Citroen C3 can come from accumulated dirt, the trouble can also come from a loose lock and finally, it can even come from a simple rivet that sits inside your bumper.
Noise in the trunk Citroen C3 : Accumulated dirt that causes poor closing
>
We will therefore begin with a trunk noise on your Citroen C3 caused by dirt accumulated on your joints, lock for example. Indeed, it is plausible that on a car that is already a few years old and whose cleaning is not always a priority or that the roads used are not very clean that dirt builds up at the trunk gasket. This trouble causes a poor closure of the trunk and a noise that can sound like a crack. To check if you are in this circumstance, open the trunk of your Citroen C3, verify the condition of the gasket that runs 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. 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 C3 that is connected to other origins such as shock absorbers, do not hesitate to have a look to this content page on the noises at the back of a Citroen C3.
Noise in the trunk of my Citroen C3 : Loose lock, clicking noise
Second possibility, you may also, over time, be the victim of a locking system that became loose. And this is one of the most probably possibilities. Indeed, knowing a trunk noise on your Citroen C3 is very often connected to this trouble. Different solutions are available to you according to the level of play you have with your lock. The first is that occasionally the offset is minimal and a simple greasing of the system with thick grease is more than enough to fix the trouble. 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 out the cover that permits 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. Don’t forget to check the centering of the striker in regards to the trunk lock. If after verifying the trunk of your Citroen C3 closes badly, it means that you have moved it too far, duplicate the procedure by pushing the striker less.
Noise in my trunk Citroen C3 : Rivet following plate change in the trunk/ bumper
Finally, one of the last possibilities. It is that following a license plate change you were unfortunate and that a piece of rivet fell at the rear of your plate. Indeed, when a plate replacement is made, to take out the old one the strategy used is to drill the existing rivets to be able to release the license plate. Sadly, 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 induce an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Citroen C3 linked to a rivet, you will need to check that it is in the tailgate open it and stir it to define 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 out the bumper to remove the bits of rivet that are running around.
