mercedez benz c class coupe 2013
When the car is in idle i get some random vibration in the cabin .It just shakes
the car for 1 time and stop. As for what i noticed it doesn't happen often .
What can it be ?
Have a Mercedes mechanic check the idle air control valve and the throttle position sensor. If the IACV is dirty, it can have a difficult time closing properly, especially at idle.
