- Mercedes-Benz E-Class: Why is My interior rattling?
Guide to diagnose trouble and recommended solutions
Interior rattles, noises and/or creaking sounds?




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
LI91.40-P-057018 SEPT13 – 212, 176, 242, 246, 204, 117, 222 creaking noise from left or right front seat belt height adjustment mechanism, replace belt height adjuster.
added a few medium density foam tape to get rid of rattles from under seat box and center arm rest.
anybody have something similar happen? or an idea what it could be? car is going in for service at the end of the month (busy schedule)

Brought it back and dealer finally fixed the creaking by replacing the driver seat rail.
Now if they can get the B-pillar ring/rattle away then the car will be up to standard. However the grease marks and stains from all the R&R will stay to remind me how much trouble this car cause everyone.

"REPLACED ENTIRE B PILLAR SEAT BELT ADJUSTER, SEAT BELT ASSY AND RELATED SIDE PANELS"




So, after the dealer replaced the center brake light that made the rattle a bit better I ended up doing the job myself this past weekend.
Took the rear shelf with the rear window blind out of the car. Found the power wire for the light in between the light assy and the blind assy and this tells me the dealer changed the light assy without taking the blind assy out of the car. It is absolutely impossible to miss the wire between the parts if it is out of the car. Easy to miss if it is in place.
Anyway, the rattle of the brake light comes from the two sandwiched plastic parts rattling against each other. I put some hot melt glue in the seam between the parts and no more rattle from the brake light assy.
Also found another rattle source. This is the seat belt "rollers" on both sides. Just a small bump on those and they make rattling noise. This is internal parts of the roller assys rattling so I don't think there is a fix for this unless someone knows about a TSB that address this issue and allow change of these under warranty. I'm quite sure MB has quiet seat belts on the S-Class...
I thought it was the fan as it seems to be slower at times and even stops but it always returns.
Any ideas?
I am thinking about having the wheel wells and trunk lined with dynamat or some other type of sound-absorbing product.
I have since deducted that the vehicle needs to be outside long enough for the roof to heat up from the sun. Then if the road is rough or I hit a bump or pothole, that produces a buzz or rattle in the headliner. Sometimes the stereo will also cause this noise.
If I tap on the headliner just behind the sunroof or at the edge next to the rear window, I can clearly hear it. Now that I know how to reproduce the sound, I plan to take it back in for service under warranty.
Any ideas what might be causing this noise?
