Answer 1

Most diesel engines are slightly rough at idle.
If it has always been like this, leave it be.
If it has recently become more rough, have a dealer investigate it.

Part of the diesel's fuel efficiency is due to it requiring very little fuel to idle. Increase the idle speed and you're increasing the fuel consumption (and hence running costs and CO2 emissions).
In a reasonably modern diesel like this, the idle speed will be set by the engine management system, so to increase it you'll need the correct diagnostics software and interface cable to reprogramme the system.

Answer 2

With the car parked and engine off, have someone push on the accelerator pedal while you watch the movement of the fuel throttle control lever on the top of the fuel injection pump. Then you'll see a simple threaded set screw that adjusts to hold the throttle lever at idle. Loosen the lock down nut and turn the set screw clockwise about 3/4 turn. Retighten the lock nut and your done. Diesels don't have a throttle plate like a gasoline engine. Instead the amount of fuel to the injectors is controlled by the accelerator cable.

Answer 3

try adjusting throttle cable
