- Mercedes-Benz E-Class: Why is My interior rattling?
Guide to diagnose trouble and recommended solutions
Interior rattles, noises and/or creaking sounds?
I have the sport suspension, no airmatic to drown out all harshness with the boaty cushion ride...
and it didn't help. I not sure the dealership has done anything about the a pillar rattle at all. Have had car in 4 times already for this alone without success.
Just brought in my CPO and the retorqued the panoramic roof so good for now.

But whatever they did fixed it as I have not heard it since almost a year ago.

I have an opposing opinion. My baby seat tether anchor point covers do not cause rattles in my car. But I just found one big source for the noise. It is the center brake light assembly that seems to be loose from the rear deck cover.




I have had this rattle at all times. Also had it with the E350 I used to own and it always gets worse in cold weather. I was checking on that long speaker cover on the rear deck but everything is fine with that but then noticed how I can stop the rattle by holding my hand on that brake light assembly when lightly tapping on the deck cover with the other hand.
And it now makes perfect sense. In cold weather the plastic brake light assy shrinks more than the hole around it making it loose.
The dealer expended a lot of effort to anchor all the small loose parts inside the 3rd Brake Light Assembly.
It did the trick.
Just replacing it would probably just continue the same issue as I don't think it got redesigned, to the degree of what my dealer did to fix it.

Thanks for the info. I also think the rattling sound comes from the inside of that brake light assembly and is just worse now when during colder weather the whole assembly seems to be loose.




I'm thinking now to tackle the center brake light rattling issue myself as I doubt the dealer will do a perfect job at it. It should not be that difficult job to do it myself, or is it?
I have an AllData subsctiption.
If you PM me your email I can send you what they have on it.
I can also send you a parts blow up from the EPC.
It sounds like the harddrive seeking inside the COMMAND unit. I wish they used SSD in them. It's random too.
They car is so quiet around so we end up hearing little noise from the new technology
My car is at the shop now for this

My previous 2012 had none of these rattles or creaks.

My door was creaking too when i rested my left arm on it but I fixed that by inserting a little rubber piece in the gap.
Let me know what you find.
(this product is the offical grease for S2000 convertible owners to keep the seals fresh and prevent dry rotting.)
It worked well on my wife's old E60 530i. Old school Mercedes used to use fabric covered weather seals and modern ones are pure rubber. Any dryness will make rubber on rubber creaks.
