Hey guys owner a 2017 c43 amg here. I’m just wondering if anybody has any input to hearing almost like a fluttering rattling noise between 2-3k rpm. It almost sounds like it comes from the right passenger side but you can hear it in the car when the windows are up. Sounds like it’s the middle front of the car where it comes from. Unfortunately I don’t have a video as it’s hard to muffle the sound of the wind with the windows down and inside the car you really have to listen for it. Also the car has a problem jerking back and forth going down to first gear usually in sport . Not sure if that’s a normal thing or idk maybe trans?(I blew mine up in my old 2013 c300) so anything related to trans or gears or noises tweaks me out. Just got the car a few months ago! Thanks to whoever.
