I've been having promblems with my skoda octavia 2021 1.5 tsi. On the car under warranty until today it has been changed the transmision and the stearing column. Now i am having problems again with the transmission or the clutch. It makes a noise while idling in neutral and the clutch not pressed in and when i press the clutch in the noise goes away. The noise is not persistant and it comes ocaisonaly only when the car is warmed up. I am attaching also a video from the sound if someone will know what it is.

I had similar issue in a 2015 Touran 1.6 TDI w. DSG box. The culprit was dual mass flywheel, but if your gbox has been recently replaced one would think they would have checked that too. But I would first check if something like heat shield plate is loose..
