Stange boost noise
I recently noticed an odd noise when the boost indicator goes past half. It's almost like a grinding noise but not as aggressive...honestly I am having a helluva time trying to describe the noise.
Not sure it's a Wastegate issue as from the videos I have seen online, mine definitely isn't as loud or constant. Again only happens when (I can visually see) the boost indicator increase past half and happens for a second.
I know I am not providing much but I am wondering if anyone else has experienced an "odd" sound with the turbo that isn't matching up with a Wastegate issue.

Remove the airfilters and put your ear in each housing. Better yet, if you still have warranty, drop your car off to the dealer.

Sort of.
I removed the K&N filters and put back in the MB factory filters. Reduced the questionable noise by about 70% (which seems odd as MB put A LOT of money and time into diagnosing this) The noise was definitely still there, but after months and hours of trying to fix it completely, they came to the conclusion it was "normal". Which is complete BS as I owned a 2018 C43 and it never made that noise.
In the end I ended up selling it and moving back to Audi and got a RS5. I loved the AMG, but the complete run around and BS in the end that I received from MB ever after owning 3 AMG's in 4 years made me jump ship.
