smola

Hi everyone
I just bought 2007 CL63 and i noticed some problem with knocking noise coming from the middle of the car. It apears when driving on sett surface but especially when speed up dynamically on high rpm, then it sound like something is knocking from under the car and it perceptible on the armrest..It sound like exhaust mounting loose or not tightened wheels but both of them is OK.
Suspension inspection showed nothing wrong. Do you have any experience with such sounds?
Thanks for any suggestions

if you can't find it the only way is with a microphone kit
