Cabin noise advice
Hey guys,
Bought a used W206 C200 2022 with 36k miles in the UK. Great car I love it except for some excessive cabin noise. When driving flat the car is silent. However when going over bumps I feel like I can hear the rear passenger door fixtures flex and cause a creaking leather friction type sound, or maybe the rear passenger doors are moving in the frame. On top of that the dashboard and trim at the front of the car don't seem to be put together well. when going over bigger bumps I can hear the dashboard creak and flex, I get the same sound when accelerating like the dash is hanging on for dear life.
I would assume these noises wouldn't be an issue when the car was out of the factory, but at 36k miles I would expect the car to be fairly silent going over bumps, except of course for the thud when the wheels go over, but the cabin should be fairly silent other than that.
I'm going to ask the dealer to take a look, my concern is, if they can't fix it, and I'm beyond my return period I'll be stuck with a car which annoys me. Has anyone had luck with dealers resolving such issues, or does anything think I should return and get something with less miles?
Thanks!

I know it's old thread, but i think it's worth knowing.
WD-40 or any standard seals lubricant is not a good idea.
It seems Mercedes is using something else for the seals at factory, and it's supposed to last car's lifetime. Of course it's not always the case.
Original Mercedes lubricant is this:
https://www.ebay.co.uk/itm/402643049369
This is basically Krytox GPL105. So you can look for Mercedes one, Krytox or... VW's solution (G052172A1). They are all the same, just find cheapest one.
Apply on the seals and they are dead silent. Did that on mine.
After doing that, make sure not to clean seals with any detergents and do not scrub them too much when washing with water, as it WILL damage a layer created by Krytox. This layer is basically sliding layer, which makes the seals slick hence preventing any squeaks.
