A noise that comes out in the trunk of your Opel Insignia is thankfully more a sign of a small correction or service, rather than a complicated one. To support you in your research, we have chosen to produce this content to present you with the most likely solutions to your problem.

Noise in the trunk Opel Insignia : Accumulated dirt that causes poor closing

We will therefore start with a trunk noise on your Opel Insignia caused 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 collects at the trunk gasket. This problem causes a poor closure of the trunk and a noise that can sound like a crack. To check if you are in this condition, open the trunk of your Opel Insignia, check 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 Opel Insignia that is relating to other sources such as shock absorbers, do not hesitate to have a look to this content on the noises at the back of a Opel Insignia.
Noise in the trunk of my Opel Insignia : 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 potential alternatives. Indeed, knowing a trunk noise on your Opel Insignia is very often relating to this problem. Several solutions are available to you depending on 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 enough 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 case you would have to take out the cover that enables 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 check the centering of the striker in relation to the trunk lock. If after looking at the trunk of your Opel Insignia closes badly, it means that you have moved it too far, repeat the procedure by pushing the striker less.
Noise in my trunk Opel Insignia : 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 change is done, to take out the old one the process used is to drill the existing rivets in order 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 cause an annoying noise. To check that it is this problem you are experiencing, and that you have a trunk noise on your Opel Insignia linked to a rivet, you will need to check that it is in the tailgate open it and stir it to discern 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.
