Cl55 sound when accelerating
Hi guys,
I need your expertise in identifying this grinding sound (4 recordings attached) when accelerating from stop position, but not heard while driving fast. Seems to come from under the engine (or slightly to the right).
Sound appears shortly after accelerating from stop position, sometimes at the beginning of accelerating, but most frequently heard 1-2 seconds after pressing on the gas pedal. More reproducible with wheels turned right or left, and worse if accelerating fast. Belt conditioner did not seem to help.
Car runs fine otherwise, but very annoying sound!
Any ideas or recommendations?
Thanks in Advance!!

No idea if you have fixed it but it could be supercharger pulley bearing (easy fix) or the belt slipping.
