- Mercedes-Benz E-Class: Why is My interior rattling?
Guide to diagnose trouble and recommended solutions
Interior rattles, noises and/or creaking sounds?
From the invoice (in case anyone in the future needs help):
PTSS Case. See previous repair attempts. Inspected vehicle with customer again. Do hear intermittent creaking noises from rear shelf area during periods of sunny warm weather. Removed all rear shelf trim and roller blind components. Inspected all as both assembled and individual parts. Found noises occurring at the 3rd brake light assembly,roller blind, speaker grill, and rear trim panel. Replaced all mentioned parts, and addressed noises during assembly. Utilized several different methods of insulation, bonding, mass dampening, lubrication, and modifications, to eliminate noise sources. A significant reduction in noise was gained by trimming both shelf panels, as to loosen the fit of the plastic grilles. Opened and closed PTSS case.

going to give it a few days before contacting the dealer about it. The car has already spent the 3 out of the first 6 weeks of ownership at the dealer for repairs. I'd hate to be without it again.

At the same time changing front grill to the Star style used on the E Coupes. I am going to keep this car a long time so don't mind this type of expense. Currently have 11,000 mi on it and for me it is a Keeper. No problems and great mpg.
Will post results in a few days.

If you're still following this thread... my seat click and tilting issue came back. The washer replacement didn't last long. After escalation to MB I got a new seat frame installed. That fixed all complaints with the seat. Until today, about four weeks later, I noticed a light clicking noise again. Not sure if that means it will develop over time and become louder or stay the way it is. Certainly the new seat frame helped a lot.
My rumbling noise from the right rear wheel hasn't been eliminated. After looking through forums I understand this can be anything from a bad strut to as small as a worn bushing. Hard to find without systematically replacing parts.
Oh and the clicking noise in the sunroof wind deflector is also still alive.
Many years ago when living in Germany I drove a 190E2.6 and it was built like a tank. Having driven all kinds of brands since then and coming back to MB this year with the expectation that all those issues from the 2000s area should be resolved it is just sad.

Is it for folding seats?
Does it sound like a rattle in the rear part of headliner or rear deck?
I just notice that after having rear seat passengers it goes away.
Therefore, whenever I put someone in back seat to find rattle it dissapears.
Car is at dealer now and of course its not rattling now.
Both of my E's had that rear "buzz" which was annoying enough to have me literally swinging my arms back to attack the seats like a mad parent trying to hit their kids. I'd usually pull over and start banging things around back there, which would sometimes help for a while.
My 2011 had an especially bad rear "buzz" which I attributed to either the furthest point of where the rear headliner ends (if you "bang" on it you'll see it's not tightened down back there, kind of able to "flap"), or coming from the rear headrests when the car was fumbling around rough roads. However, with more miles it seemed the rattles on my 2011 actually got better instead of worse.

I remember watching the W212 development phase very closely and I rarely if ever saw "Sport" models being tested. It seems the car during its extensive and rigorous development/testing phase was definitely dialed in more closely and tested more thoroughly as a Luxury/Elegance model indeed.




Yesterday took the trunk floor up and installed paper towel between all the tools and between plastic parts for the tire change tool kit. Also put a 1" thick cover on the spare wheel and the tool kit under the floor.
RATTLES AND ANNOYING SOUNDS 90% GONE!!!
I think majority of the noises in my car are coming from this stupid compact design spare wheel / tool kit combo.

I am pretty lucky as my W212 is pretty tight. However I do foresee some of these fixes with paper towels, cardboard and whatever other felt will come in handy. There seems to be a couple weak spots inside the W212's
I have the sport suspension, no airmatic to drown out all harshness with the boaty cushion ride...
