2L Mk 5 Aux belt tensioner

[85Fuego]

Dear knowledge base:

Been a while since posting last - no problems with my 2005 2L TDI, until now.
The auxilliary (serpentine) belt tensioner is on its way out.
Rattles away on startup and then goes quiet.
106k - DSG.

Get genuine or is a quality repro good enough?

Any leads/thoughts?

Local/net purchase?

Thanks.

David
