hello to all . i bought a MB cls 350 year 2005 (200 kW) like a month ago and now i have noticed that when i reach 1600-2500 rpm i can feel vibration inside the car and it doesnt matter do i stay in P N or i am driving . yesterday i change all the spark plugs and the problem still stays . if anyone know anything about it or is it normal ?
Thanks in advance
