If you find a noise on your car, you are right to be aware of it and take it seriously, although it is plausible that nothing major will happen, it is also plausible that it is the indication of a more critical repair. A noise that comes out in the trunk of your Volkswagen Transporter 4 is fortunately more a indication of a small manipulation or repair, rather than a difficult one. To support you in your research, we have decided to write this article to present you with the most likely solutions to your problem.

We will therefore start with a trunk noise on your Volkswagen Transporter 4 created by dirt accumulated on your joints, lock for example. In fact, 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 collects at the trunk gasket. This problem causes 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 Transporter 4, 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 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 Volkswagen Transporter 4 that is connected to other origins such as shock absorbers, do not hesitate to have a look to this article on the noises at the back of a Volkswagen Transporter 4.
Noise in the trunk of my Volkswagen Transporter 4 : Loose lock, clicking noise
Second probability, you may also, over time, encounter a locking system that became loose. And this is one of the most likely possibilities. In fact, knowing a trunk noise on your Volkswagen Transporter 4 is very frequently connected to this problem. Some solutions are available to you subject 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 mechanism with thick grease is appropriate to solve 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. Be sure you verify the centering of the striker in relation to the trunk lock. If after verifying the trunk of your Volkswagen Transporter 4 closes badly, it means that you have moved it too far, replicate the process by pushing the striker less.
Noise in my trunk Volkswagen Transporter 4 : Rivet following plate swap in the trunk/ bumper
Finally, one of the last possibilities. It is that following a license plate swap you were unfortunate and that a piece of rivet fell behind your plate. In fact, when a plate change is made, to take out the old one the technique used is to drill the existing rivets to be able to put out 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 provoke an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Volkswagen Transporter 4 linked to a rivet, you will need to verify that it is in the tailgate open it and stir it to distinguish the noise. If this is your situation, you will have to take out the linings from the trunk to remove it. Finally, if it is your bumper, it is in this rarer and more disturbing situation, you will have to take out the bumper to remove the bits of rivet that are running around.
