Thumbs down Engine 'Thrum' Noise Advice

So... to get things off my chest... my new 18d Sdrive modified clutch is now 100% juddering again. I’m so annoyed.

The main reason for this post is another noise that's got worse and was there before I had the clutch changed.

At idle there's now a 'Thrum' noise like a shaft of some description is wobbling about or possibly an engine mount is worn and the engine is moving about too much???

I can get the noise to appear if I pull away slowly with too little gas, but it doesn't seem to be there once I've got moving or up at speed etc. Just at idle and more noticeable when cold.

If you can imagine getting a hard rubber covered stick, put it into a slightly larger circle of metal (also covered in hard rubber) and wobble the stick about quickly... that's the sort of noise I'm hearing. A dull thrum thrum thrum thrum thrum thrum.

Any ideas? Prop shaft, drive shaft, engine mount?

Will be talking to my dealer soon, but thinking about trying another dealer to be honest.
