If you find a noise on your vehicle, you are right to be concerned of it and take it seriously, although it is plausible that nothing significant will happen, it is also plausible that it is the sign of a more important fix. A noise that appears in the trunk of your Volkswagen CC is fortunately more a sign of a small adjustment or restoration, rather than a complicated one. To help you in your research, we have chosen to produce this content to present you with the most likely solutions to your problem. First we will see that this trunk noise on your Volkswagen CC can come from accumulated dirt, the problem 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 Volkswagen CC : Built up dirt that triggers poor closing
>
We will therefore begin with a trunk noise on your Volkswagen CC generated by dirt accumulated on your joints, lock for example. In fact, 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 accumulates 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 circumstance, open the trunk of your Volkswagen CC, examine the state 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 improvement. 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 Volkswagen CC that is linked to other sources such as shock absorbers, do not hesitate to consult this content on the noises at the back of a Volkswagen CC.
Noise in the trunk of my Volkswagen CC : Loose lock, clicking noise
Second probability, you may also, over time, be the victim of a locking system that became loose. And this is one of the most likely possibilities. In fact, knowing a trunk noise on your Volkswagen CC is very often linked to this problem. Several solutions are available to you subject to the level of play you have with your lock. The first is that in some cases the offset is minimal and a simple greasing of the mechanism with thick grease is good enough to eliminate the problem. 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 circumstance you would have to strip off the cover that will allow 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. You should verify the centering of the striker in regards to the trunk lock. If after verifying the trunk of your Volkswagen CC closes badly, it means that you have moved it too far, repeat the procedure by pushing the striker less.
Noise in my trunk Volkswagen CC : 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. In fact, when a plate swap is done, to take off the old one the strategy used is to drill the existing rivets to be able 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 create an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Volkswagen CC linked to a rivet, you will need to verify that it is in the tailgate open it and stir it to identify 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 embarrassing case, you will have to take off the bumper to remove the bits of rivet that are running around.
