We will therefore begin with a trunk noise on your Bmw Serie 3 triggered by dirt accumulated on your joints, lock for example. In fact, it is plausible that on a automobile 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 problem 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 Bmw Serie 3, verify the state 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 difference. If this is not the case, continue to the other hypotheses that will probably give a solution.

Second probability, you may also, over time, experience a locking system that became loose. And this is one of the most potential alternatives. In fact, knowing a trunk noise on your Bmw Serie 3 is very frequently related to this problem. Several solutions are existing to you depending on the level of play you have with your lock. The first is that quite often the offset is minimal and a simple greasing of the system with thick grease is more than enough to resolve 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 out the cover that permits 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. Make sure to verify the centering of the striker in connection with the trunk lock. If after checking the trunk of your Bmw Serie 3 closes badly, it means that you have moved it too far, duplicate the process by pushing the striker less.

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 change is done, to take off the old one the technique used is to drill the existing rivets to be able to put out the license plate.

To check that it is this problem you are experiencing, and that you have a trunk noise on your Bmw Serie 3 linked to a rivet, you will need to verify 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 problematic situation, you will have to take off the bumper to remove the bits of rivet that are running around.
