Unidentified sound out of nowhere C55 AMG
I’ve got a C55 and it recently developed a sound I cannot identify, it drives fine but it has like a misfire or other noise.
There are no codes, smooth running data is quite clean at 0-2.5.
Has anyone had an issue like this? I would greatly appreciate any help.
Thanks
