6sp manual clutch judder

My sept 14 SD4 manual Evoque has developed a juddery clutch, mainly on take off and 1st to second, and sometimes I can feel it when going into third.

I've only had it 3 weeks, bought approved used, so I've emailed the dealer with my issues (there are a few others too), as they are a long way away so the car is booked into my local dealer, but covering it in case I have to reject the car if they won't fix it.

Is this most likely the Flywheel or something like an engine mount.

Bit of an update. New clutch and flywheel currently being fitted by the dealer under warranty

Hope that sorts it Harry.
