Dmf+clutch kit recommendation

[Wc04los]

Dmf on my transporter is chattering its tits off (2017 and 48k miles) which I think is p!Ss poor. Its a dsg if that has any influence on what to get.

Any recommendations on what brand to get? Also having the timing belt and water pump done the same time, so same question applies regarding them (oem or aftermarket)?

TIA
