Hello guys, can someone suggest me whats wrong. Last week I bought 2002 Volvo S80 D5, and while the car is cold and standing its vibrating, but while driving it stops.

Even when i check the engine under the hood, its vibrating very much.

 

check the motor mounts - if like the I5 gas engine, there's one up by the nose (#1 cyl)

 

Can you explain simplier, I am not good with english. You mean one engine mount is responsible for vibration, undsr first cylindre?
