Hello guys,
I have a 2012 w204 c63 with 49k miles .
Stock exhaust, stock car.
I have this annoying rattling/buzzing a sound like a diesel engine running coming from the right side (RHD) every-time I accelerate on low speed in higher gear (normal city drive) from 2000rpm till 4000rpm
Video:
Every-time i let go of the accelerator paddle and apply some gas this metallic buzzing/ rattling sound comes, can be heard in the video.
I have taken the car to have the exhaust checked and found zero leaks, changed the header gasket just in case , didn’t fix it.
Checked the cats they were in good condition , even swiped then with my friends car but the sound is still there.
Anyone suggest what could be causing this sound inside the car, i can hear it very low when the car is in park and i give gas, but when driving it more noticeable.
