C63 AMG Noise Over 45 mph help
Hello everyone, I recently bought this car from a fellow member here and since getting it home is seems like I picked up a new noise. Only happens when I'm going over 45 mph or so. If anyone is familiar with this or has an idea please let me know. Thanks.

It's hard to tell from that video. Where does it feel like the sound is coming from? From that vid, it almost sounds like it's coming from inside the cabin.
Have to tried doing an RPM test? In other words, is it tied to speed or RPMs? Can you get it to do it in lower speeds by holding it in 1st or 2nd gear?
I've had some crazy noises that turned out to be things like sticks trapped in the undercarriage. I assume you've looked in the engine compartment and under the car to make sure you didn't pick up a plastic bag or some other highway debris?

10 C six trizzle
sounds like a heat shield rattling, could be a loose under body panel too. I've seen a lot of rear diffuser installs done where they are loose and floppy and sound like that. But being that it's a video that's a rough guess.
