Hi William,
I have not received my replacement yet but I have no reason to believe it is anything but a new unit.
I have sent mine back and they are in the process of returning it.
Below is a screenshot of my “Exchange Summary”.
Note I am returning a 2875.62 and getting back a 2875.04 which I believe is basically a unit without the freehub.
Returning:
NEO 2T Smart
T2875, Tacx, GB
T2875.62
Qty: 1
Receiving:
NEO 2T Smart resistance unit
Service Only
S2875.04
Qty: 1
Hope this helps,
Martin.
