Insignia - A20DT engine questions

[jmmbl]

Hello,
just noticed a few problems with my car.

1-The engine vibrates alot, and has a rough idle (vibrates alot in the steering wheel and the car when driving around 43mph, been at my local workshop to diagnose this. The injectors have some different values (leak test)
also had 2 fault codes on the glow plugs - replaced and no fault codes. But the engine still vibrates and have a rough idle.
I been talking to the workshop, and they say it could be dualmass flywheel / or the injectors that need to be replaced.

2- When i drive the car - it feels sometime that something ''bites'' when i shifting gear, almost like a bad clutch.

Whan can cause this kind of problems?

Have you guys any tips regarding this?
