How bad is it? These TFSI engines are seriously tappety beasts, sound like diesels most of the time.
Whilst stationery, if you pop it in the 3rd, handbrake on, and slowly release the clutch (not fully you'll stall), does the clutch slip or does the car pull against the handbrake?
If it isn't directly effecting your drive it sounds very much like a worn clutch / release bearings / dmf etc. all solved by replacing... but why do that until it really needs doing?
Of course that's all imho :)
Have you got Full SH with up to date Cam belt and tensioner, water pump etc?
