T6 DSG with 70k on the clock here and I seem to have the same issue. On idle in neutral, I hear a chattery sound come and go intermittently. Been under the van and it definitely sounds like it's coming from the clutch/flywheel. According to the history it also had these changed at low mileage (around 30k) under warranty due to a sound reported by the owner at the time.
Sound recording attached. It sounds a lot louder than it is as my phone is recoding right next to the flywheel.
Has there been any developments on why this issue tends to occur, is it conclusively the Dmf, clutch or possibly one of the bearings which has a tendancy to go?
Will it eventually go pop and cause other issues or am I ok to ignore it for now?
Are there any clutch/dmf/bearing part numbers/revisions/brands to avoid or specify to fix?
Thanks
