Guys I just received my fresh A35 FL!

Everything so far has been amazing, no major complains however there is one thing that bothers me just a bit.

When I am accelerating/decelerating or switching from D to R I can hear this weird sound from the back. It reminds me of some sort of valve opening/closing mechanically or if I had a huge spoiler which would adjust when mentioned criteria are met. It lasts for 1-2 seconds and then disappears until next acceleration/deceleration. It is also worth mentioning that this happens at low speeds and I don't think its something moving in my trunk as I have also heard it when switching from D to R and standing still.

Is there something I don't know (not a huge motorhead here so I wouldn't be surprised).

Any tips for brand new A35 owners are also appreciated, thanks in advance

Could be the rear view camera closing up?

Have you ever found out what the noise is? I just bought a brand new A35 3 weeks ago. and I have also noticed this noise. It cant be the camera can it? Why would it open a close while decelerating or stopping? Is it maybe the mild hybrid battery?

battery for the hybrid system is in the boot, could be something related to that a solenoid or relay or something if not then the reverse camera is quite loud

Pour résoudre le problème de bruit étrange provenant du coffre de votre Mercedes A35 2023, commencez par vérifier que tous les objets dans le coffre sont bien rangés et ne bougent pas pendant la conduite. Ensuite, examinez les charnières et les amortisseurs du coffre pour voir s'ils sont desserrés ou usés. Assurez-vous que le joint d'étanchéité autour du coffre est intact et en bon état. Si le bruit persiste, il serait sage de consulter un mécanicien pour un diagnostic plus approfondi.
