This serious vibration only occurs when in gear and parked, then disappears as soon as the car takes off. The engine does not really shake that much when I look at it under the hood and have someone engaging the transmission in Drive.
Would this problem still be due to engine mounts only (current mounts have about 100K Mi)?
It it was an ignition problem, it should happen all the time, right?
If it is only engine mounts, they are hydraulic and also available as less expensive after market parts: are these OK to use instead of MB parts?
THKS!
