Default Worn out flywheel?

Long story short, my car developed about half a year ago a ticking/tapping noise which got gradually worse, thought it was from one of the timing parts of the engine, replaced all 3 belts, all the pulleys, tensioners for both main and aux belt, and still nothing's changed, thought it would be the tappets, so I bought a mechanics stethoscope to closely listen to the engine and found out that it's something completely different, the sound was coming from the transmission. And since I've replaced the clutch kit about 10-15k miles ago the only logical explanation would be that now it was the flywheel that gave up, because that wasn't changed, I am thinking this because, as far as I know, when flywheels are slightly cracked or worn, they start making rattling or tapping noises which gradually increase. In my case, yesterday I found where the tapping is coming from, and guess what, today the clutch started slipping while IN GEAR and I started smelling that typical clutch smell. I'm writing this in uppercase letter because it should be noted that in only slips when the car is already in gear, but it shifts perfectly fine which leads me to think that the disk and other clutch parts are not worn.

My question is, is it possible that the almost new clutch disk has got premature wear because of the faulty flywheel making it needing to be replaced again? It would really suck opening the transmission and finding out that I have to replace that too even though new disk and pressure plate + master and slave cylinder were fitted 10-15k miles ago...

The dual mass clutch is an invention of the devil, and can give all sorts of problems.
They are far less reliable than the old fashioned clutches.
I have had dual clutch clutches fail after 2000km.
I will never buy a car with a DMF.

I thought the petrol engine cars had solid flywheels?

My 1.8L petrol has a dual mass flywheel! Original clutch plate was solid, no longer available, so now has clutch plate with springs. Very noticeable difference when changing gear.

I also thought it was a single mass flywheel until I asked my mechanic that fitted the clutch kit 10-15k miles ago and he told me it's certainly a dual mass one, should've replaced that too... But still my question stands still, do you think that the disk worn out too in such a short time if the flywheel has been developing the ticking for the last half year and if today only it started slipping? I really cannot see how such a fresh clutch disk could possibly wear out so fast... But still, if I'd know I wouldn't ask.

From what I have read on here , It is very rare for the DMF needing to be replaced many have been OK for well over 250-300K miles.My car is approaching 200K on the original DMF without any problem. So I would be looking elsewhere for the problem with your clutch.

Yep they can fail but mine has covered over 400k miles and still on the original DMF.

Mine covered over 150k now... But now I'm asking, how could other clutch parts besides the DMF start tapping? I closely listened with the stethoscope and the tapping comes from right under the DMF. Or especially make the car vibrate, and by the way this is also a small update on the matter, I started the car this morning to see how it acts while idling and no matter if it's in gear or not, the whole car is vibrating/shaking, and I don't think other transmission parts couldcbe responsible for that. Or could they?
