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

1) Somewhere front/center left side of the panoramic sunroof when going over bumps. It is more a ticking noise so it sounds like somethign has play. Haven't found the source of it yet.
2) Noises in seat. Seat tilts even when push by hand. Rails are tight, almost looks like the seat frame has an issue and the second noise comes from where the back meets the bottom parts. Makes a clicking noise when coming to a stop and accelerating.

@chrisvr6: The clicking noise is gone. Am happy about that.
Only issue left is that the driver's seat is also moving back and forth a bit when braking and accelerating. Dealer says it's normal since all E class on the lot show the same behavior. Might be common but I never owned a vehicle before where the seat has play to a degree that it can be clearly felt.
If I can find a diagram I will try to investigate the possibility of inserting some felt or a washer somewhere in the seat frame.
Panorama roof noise: Found the issue. Clicking noise came from the wind deflector plastic frame which pops up when opening the roof. I installed some felt below the frame and now it's quiet.

Overall a very solid car!

Noise originates from B-Pillar. They removed the headliner to make sure and then proceeded to remove the roof trim, and reinstall and tighten.
Re-tightened the sunroof frame bolts - noise gone while driving over 120 miles today.
Totally different car without that series of rattles and pops!

My car seemed cured for about a week, but I am getting a random pop or crack again. As the weather gets warmer here, I fear it will get worse. I am going to suggest they inspect the same areas addressed on your car, if it keeps up.
