Knocking on wood again, even with the rough roads and Pano, I'm not getting any rattles, except for the mentioned occasional "squeek" from somewhere behind the wheel/inside the dash, which is a problem that isn't a technical rattle I believe (it's gonna be fun trying to get the Dealer to diagnose this.... Maybe impossible).

Sucks to hear that anyone is having rattle problems. It easily ruins the experience of driving/owning a car, and is difficult to get fixed on some occasions, at least without being extremely diligent with a Dealer, and being able to diagnose it/have it happen while in their presence.

Had same problem, was the hood hitting the bumpers it rests on. Put anything soft over the bumpers and the problem will be gone

Same issue here, fixed it with applying 3M tape on the hood where it hits the bumpers...

I ended up putting some lub on the hood bumpers. That fixed it. I asked the dealer to lub them as well. Problem gone.

My W212 only has 6k miles and the front suspension already making very annoying squeaking noise when going over speed bump or getting into and out of the driveway. Sometimes I hear popping noise and notice chassis flexing noise on the drive side door when going over speed bump. There is also constant rattling noise near the rear sunshade. I have driven older Audi, MB and Range Rover and the W212 is by far the worst car I have ever owned.

Anyone has similar issue and have the dealer fix all the problems?

my dad's W212 has a rattling noise coming from the passenger seatbelt buckle, will take it to the stealer for fixing soon

I've had both of these issues!

1. popping / cracking sound coming from roof pano. I had this almost happen in the first 3 months. Was like this for 7 months before i finally took it in. Dealer fixed it, they told me they "cleaned it". But i think it was grommets popping out of place and they probably just removed the gromets! A quick short cut fix. Whatever they did, it worked great. No cracking / popping anymore.

2. the creaking is the center vent. took that in too, they have TSB on this, they just add some felt chalk on the back of the vent. Fixed it for a few months, now it's creaking again. will take back again to fix, but hopefully this time it'll be more permanent.

Hope that helps.

I had similar squeaking noise from the front of the car when going over speed bumps and getting into driveway/garage. I fixed it by putting some 3M tape over the hood stoppers by the wheels arches. Squeaking gone. It worked great. Good look.

I have the same problem, i purchased my E350 5months ago and its been in 5 times and always comes out with the rattling being worse? when i purchase the vehicle iv been getting this rattling sound from day 1 its appearing to be coming from the middle console/ dash.... am i entitled to a refund? or a exchange?

Fixed my rattle this way.

iv tried that, it dint work for me, its booked in again tommorrow, i spoke to main customer service and they assured me the car will be fixed with in 4 days.

Had this with my 06 e3504matic. Was the shade itself which the dealers refused to replace. They just kept added felt to the back and hoping I would go away. I did I sold the car. I knew mine was the shade because it went away when I had the shade up.

On my (new since my last post in this Thread) 2011 E, the rattles are on and off. Sometimes it's silent, then sometimes random rattles/vibrations, etc, pop up. I don't see how they wouldn't since THE SUSPENSION IS SO HARSH OVER ROUGH ROADS THAT EVEN THE TIGHTEST INTERIOR BUILD WOULD START RATTLING/SQUEAKING AFTER SOME TIME, WHICH IS EXACTLY WHAT'S HAPPENING.

Recently everything was good, and now some sounds from the rear are popping up again. I can't stand even the slightest vibration/rattle/squeak sound, makes me want to drive the car off a cliff (without me in it).

same problem plus
 

Have the same problem, but also if car is parked in sunlight for few hours on a hot day, very noisy when I open it. Scary-sounds like it is going to break. Earlier poster said dealer should lube it when go in for service. Going for B and it's on my list of problems. 5th car with a sunroof and never had this situation before nor had one needing lubrication.

I think the newer, environmentally safe, plastics, contract and expand much more than the softer plastics. The best way to eliminate them is to find the plastic pieces and remove them carefully and apply krytox 205 grease to the areas where the plastic-on-plastic squeaks/creaks are happening. A good example is the wood trim, it can be popped out and krytox applied (extremely thin layer is all that is needed) and reassemble. I notice the trunk area stowage (adblue for me, spare for the rest), I added a fat piece of automotive felt where the stowage panel closes, that eliminated the rough sounds over bad pavement. I also had a rattle from the mini sun visor on the passenger side. It seems there is a rubber "bushing" on my driver side, but absent from the passenger, so I stuffed the tip of a q-tip into the area and solved that one. Takes a little creative engineering sometimes, but this car is far free of squeaks/rattles than any BMW or Lexus I've owned, even my LS 430.

Hey just wanna let you guys know that there are some w212's out there with noise from the Pano-Roof. My 2010 E 350 is at the dealer now waiting on the entire Pano-Roof assembly for popping noise when the body flexes i.e driveway approach. It was mis-diag.couple weeks ago where they replaced the overhead controls. Brought it back since the noise never went away to road-test it with the foreman,the noise was present as soon as we came out the dealer. So this is where it stands for now till i pick it up.

Did you mean to write 220? The W220 never came with Pano roof actually.

I meant w212:D I do have a w220 and screen name has w220. thanks:y

Hey guys,
I was going to post a picture of this, but did not get around to it.

I have a 350 that is only 3 months old. I HATE interior noises....really bugs me. Unfortunately, a $60K mercedes has them pop up just like any other vehicle....sucks

I had a ticking noise coming from the dash. Since I have experience tracking these things down, i took the car down a crappy road and started tugging and pushing on surfaces until the sound stopped or changed. Sure enough, it was up in the gauge cluster region. At first, I though it was the far left vent assembly because the noise would stop if I pressed down on the corner of it. I took that assembly out and all looked solid. After reassembly, same story, ticking came back.

I decided that since the pressure was working, it must be something close to the vent assembly that was making the noise. I started pushing on the inner-shroud piece just above the guages...it seemed to also stop the noise.

With some gentle tugging, the ineer shroud pops right off. I could see there were two main points where the plastic guides appear to be the most likely culprits. Sure enough, I applied the soft side of a self-adheshive velcro strip, about one inch long, right next to the pins and guides. This provided soft pressure on the guide and snugged them up.

Re-assemlbed the shroud and the ticking dissapeared.

I hate this stuff, but happy I found the problem...of course, I would have torn the entire car apart to find it eventually...either that, or the car would have been sold.

^^^ I'd love to see a photo of that area you fixed.

I'm down to one "buzz-rattle," which I think is coming from the trim piece betweeen the headliner and the rear window. There is a frame at the top of the back window finished in the headliner material. If, while parked, I bang around that area, the sound is similar to what I hear when driving. Of course, the road bumps have to be just right as I don't hear this all the time. And my problem is that I can't be in the back seat and drive at the same time to truly isolate the source. It isn't bad enough for a trip to the dealer, but would prefer to eliminate the sound altogether.

I think one of my on and off buzzes is that same thing as well. I need someone to drive my car while I sit in the back and figure it out. How delightful that sounds. :rolleyes:

YES!!! and none of my trim removal tools seems to be able to remove that piece. I wish we had a "realoem" type of site like the BMW crowd has, so we could see how these puzzle pieces of fisher price plastic fit together.

Ok, I actually have a picture from the dealer that will work. It is the trim piece right below the dash and above the guages. Here is a picture that partially shows it. I have a loop around it.

That helps a lot, I will look and see if there are any mini screws that hold that pig together and possibly apply some krytox 205 to the back of it and reassemble it. Felt is probably too think for this trim piece.
