A noise that comes out in the trunk of your Audi A7 is fortunately more a signal of a small manipulation or repair, rather than a complex one. To help you in your research, we have chosen to write this article to present you with the most likely solutions to your issue.

Noise in the trunk Audi A7 : Accumulated dirt that causes poor closing

We will therefore begin with a trunk noise on your Audi A7 generated 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 main concern or that the roads used are not very clean that dirt accumulates at the trunk gasket. This issue causes a poor closure of the trunk and a noise that can sound like a crack. To verify if you are in this scenario, open the trunk of your Audi A7, check the condition 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. 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 Audi A7 that is linked 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 Audi A7.
Noise in the trunk of my Audi A7 : Loose lock, clicking noise
Second possibility, you may also, over time, encounter a locking system that became loose. And this is one of the most likely alternatives. Indeed, knowing a trunk noise on your Audi A7 is very often linked to this issue. Different solutions are available to you depending on the level of play you have with your lock. The first is that sometimes the offset is minimal and a simple greasing of the system with thick grease is sufficient to eliminate 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 circumstance you would have to take out 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. Remember to verify the centering of the striker in regards to the trunk lock. If after looking at the trunk of your Audi A7 closes badly, it means that you have moved it too far, replicate the operation by pushing the striker less.
Noise in my trunk Audi A7 : 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 backside your plate. Indeed, when a plate swap is done, to take off the old one the process 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 Audi A7 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 situation, 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 situation, you will have to take off the bumper to remove the bits of rivet that are running around.
