The most annoying rattle in the world

Hello

please please help…. I’ve inherited a hideous rattle coming from the rear passenger side on the parcel shelf on my A238. Literally any uneven road surface (from Essex so that means everywhere 🤦🏼‍♂️) is when it’s worse.

I’ve been in the back and can’t pin point exactly where it is on that area.
there is next to no movement on the joins. I’ve had the roof partially open to look underneath and again seems to be nothing loose or out of place.

hoping for some help before I drive the thing off a cliff whilst I jump out 😂😂😂😂😂😂😂😂 it’s that annoying 😂

Are you sure the rear seats are locked in place? I once pulled the lever in the trunk and caused one of the seats to be slightly loose. That may be worth checking.

I just reread the thread and remembered my A238 does something similar but the issue is the seat belt. It doesn't have enough tension on it so it rattles sometimes, especially with the top down. I pull the rear seat forward and stick the buckle in the trunk to hold it still. Without a video I can't say this is your problem, but worth a look.

I once had a noise that turned out to be coming from the loose 5-point harness on a child car seat in the back. Had to remember to click all ends in every time I drove.

yes mate found it

it was the parcel shelf where it comes down for the roof

I used some foam tape (draught tape 2mm/3mm) see attached under the parcel shelf along the edge and it stopped straight away.

pretty poor from Mercedes that it’s does this

Thank you very much @Louis. Highly appreciated. I know I'm asking a lot, but can you perhaps share a photo from the car, of the exact location where your problem was? Pardon me asking, but I'm no expert in trouble shooting, and appreciate all the help I can get

Agreed. I have no idea what you mean by the phrase "the parcel shelf where it comes down for the roof."

I had the same issue with my wifes car. The foam tape is a definite fix. You have to apply it on the front edge where the parcel shelf comes down and meets with the area just behind the rear seats. I raised the roof until the shelf with the two speakers was raised up and just ran the tape all along the joint where the front of the shelf meets the car when it lowers. Car is silent now.

Here are a few pics of the area. You can see where I put the tape in the second pic.
