Here we go. Mine + eBay spares, to build one decent unit, lower plunger assemblies are still together, meaning they are seized!

Yeah, don't you just hate how those red pistons get stuck in the end of the nut assembly.  Once you get them the tiniest bit loose they go shooting in some unknown place in the shop. 

I was able to obtain a second proportional valve from another VW parts collector, Thanks Dave, but I wonder if my pistons are still hanging up.  I just don't get the stopping power from the rear brakes.  That leads me to think that they are not staying charged and when I step on the brake pedal most of the first stroke ends up setting up the brakes for a proper stop.  But who double pumps brakes? 

Going to fiddle with them again when the weather warms up.
