noisy interior
Why does my 60k 2019 c43 interior noise sound like it is a cheap piece of ****. Seriously i was in awe of the power and exhaust option when i bought it and not expecting it to be quiet inside like a lexus but damm. Makes is seem like it is a cheap car. Even thought about abandoning MB all together or trying the Sclass in time.
Anyone else have this issue

I have a slightly older c450 and noticed 2 things rather quickly. Their is a lot of road noise from RF tires, and the dash/instrument panel has a bunch of creaks and squeaks..Not what I expected..The RF noise was helped a lot by a tire replacement..The other creaks and squeaks remain. Is this the kind of stuff you are talking about?

With these cars you get a lot of interior squeaking noises and road noise due to hard suspension and wide wheel base; it is just the way it is. Noise insulation is actually pretty great because I can hardly hear my own horn if the music volume is a little high. But insulation cannot block the road and interior noise, only external ambient. I have owned BMW M and pretty much the same deal.

I agree with the above-comments. Road noise is lessened with non-run flat tires. Also, my PFL coupe has some occasional interior creeks, but not bad at all. Finally, I also believe the sound insulation is pretty decent in the c43, as the difference between my downpipes and FI Exhaust between windows up and windows down is HUGE.

I too was unhappy with my cars sound levels and ended up adding more insulation to all the doors, the rear passenger area, the trunk floor, inside the rear wheel wells, and the two plastic underbody panels of the car. The car now has the noise levels you would expect of a higher level Mercedes.
With respect to squeaks and rattles, I would suggest removing the center console and applying cloth tape to all places that connect plastic to plastic. I covered all clips and mounting tabs throughout the assembly. Also, remove the outer chrome band and back it with the cloth tape.
Additionally, I run non-RFT tires (DWS06 Plus) and that makes a difference too.
It took a lot of time and work to do this, but the results made it worth the effort. All-in-all I used a 36 square feet of dampening material and 54 square feet of 3/8" jute carpet padding for added sound absorption. Just returned from a cross-country trip and the transformation was a game changer.

The dampener is listed as 24 ibs. and the jute padding lists for 12 lbs. I did the job in two steps and never considered trying to get a before and after reading. I have done the same thing on other vehicles and was confident that the results would be worth the effort. Pricewise, one of the best mods you can do for this car. Make that second-best; buttoning down the console should be fix number one.

2019 W205 C43 Sedan - Socials @Vip.C43
My 2019 C43 Sedan creaks and squeaks like a **** but then again I am on air ride with stretched tires. I think my aftermarket subwoofer might have loosened some panels up as well.

2018 AMG C43 Cabriolet
2018 C43 cabriolet it’s squeaky nothing too bad I am impressed with the quiet ride (little road noise) for a convertible. I also find the squeaks subside after running the car for a while but maybe I just get used to it
