checking mechanical condition of AWD

New p2 owner here. I'm trying to assess how much I should put into trying to fix my AWD system on a recent purchase. I jacked up the rear of the car to check the operation of the differential expecting it would either be difficult to turn a wheel, or the opposite wheel would turn the opposite direction (open diff) but I observed neither. Each wheel turned easily as though the inner end of the axle shaft was hooked to nothing at all.is this normal? Is the pinion gear simply turning freely inside the Haldex coupling system? Shouldn't the rear wheels turn together as a limited slip diff normally would?

Also, the PO had disconnected the power plug to the Haldex pump. I have not plugged it back in to see what happens yet...
