A friend has an auto 320d auto on a 53 reg. The car runs lovely and drives perfect but has a really bad vibration through the whole car at idle. It dissapears with slight throttle. The engine mounts have been checked as have the crank pully. Today car went on diagnostics and showed no faults. We also removed swirl flaps today. We are out of ideas and googling problem gives no real answe
r.. feel free to offer an opinion.

Does the engine itself idle smoothly or does it misfire?

No missfire.

Have you tried to reset the ECU adaptions? so the ecu can re learn its idle stategy

What fuel is it on?

This is a common thing on these can be caused by injectors,Can also be caused by the terminals on the fuel sensor on the end of the common rail .
