Has to be 025 121 062 E if you have manual trans.

I'm guessing (inch-plus hose, yes?) 251 121 058 A, from large nipple
on top of coolant manifold across to thermostat housing.

That hose will depend on which manifold (tower) you have. If you can
get the p/n from it that will simplify things. The basic story is
that early 2.1l up through VIN ------24-H-022956 use different
manifold (251 121 438 and 438 A) for manual and automatic. After
that they both use 438 B with the nipple to the head located
differently and the transmission cooler on the automatic is fed by a
fantastically expensive special hose instead of an extra nipple on
the distributor. The two earlier manifolds use 251 121 130 A to the
cylinder head; the later one uses 130 B. But if the manifold has
been replaced it may not be the same one originally installed.

Two hoses, coolant actively circulates through it (and it's a bubble
trap that bleeds off into the overflow tank). It has a level sender
and O-ring screwed in the top, a couple of s/s pins insulated except
for the bottom few millimeters.

I think you're looking at an oil slinger (or as VWAG calls it, oil
thrower) p/n 025 105 241. It's the front line of defence, keeps the
seal from being flooded. I'm not an engine builder, but I'd say it's
important.
