Hey,

New to the forum but I'm picking up a 2019 C43 AMG that has CTS intakes on it. I've been combing the forums for this issue that several people have posted about but never posted that they resolved the issue.
No noise happens under hard load.

Ill attach a file that another member posted as it is the exact same noise

Regardless of the issue I'm keeping the car / just want to fix this as its the only issue with the car.

Will follow up with a fix.

Noise happens when:
40-70 KM/H
Car starts to build up boost
Under light acceleration

 

Heres the file from another member on here.

 

Since its only making noise when building boost, I would definitely check turbos. Check to see if the intake has any broken pieces or anything that can be sucked into the turbos, I've seen some posts about the insides of the intake being broken off and flying into the Turbines causing it to break/chip. Does it feel like your car is losing power or boost?

 

Aftermarket CTS intakes and took off both intakes and inspected both turbos and they physically look ok.

 

having the same issue, any findings yet TS?
