Think you are confused on what the governor might be.
Control sleeve is a 'spill collar' - that and the pump plunger are a matched pair.
I'm glad I did pull these pumps apart. I wonder how many people buy a secondhand pump from eBay and simply swap them over? I've had these on the shelf for just two years and both were pulled off working engines.
The control sleeve on the ACV pump was solid, the EDC simply could not of worked. It may have been run on veg oil too as the internals have "sticky fatty fuel" deposits in the body unlike the Volvo unit which was clean internally. The control sleeve was not free either but did move.
All of the components in (3) above are replaced by the electrically controlled EDC in the TDI engines.
I've got none of this.

See it all the time - 6 months with an open port is enough to gum these pumps horrifically - first to seize is the vane pump, but you cannot see it, a good (bad) indication of a gummed pump is a yellow brown residue and a sticky fuel spill collar.
The number of people that decide they cannot afford to pay for a pump rebuild so buy a 'working' pump from eBay - guess how many of these 'good running' pump end up with me for a full rebuild.
Got involved in an argument with an ebay seller a while ago - the pump he had sold was not just gummed but extensively rusty. He said it was running when it was removed a few weeks prior so I sent photos and he ended up saying that it must have gone rusty whilst in the post!
Yep. As I suggested, I need to pull one of these pumps properly - is the governor solely electronic?
I've developed a real admiration for these pumps and realise it's such a fine tuned piece of engineering balancing the internal pressures to deliver timed fuel as it does - it's quite fascinating and NOT for the faint hearted that's for sure.
The governor is totally electrical. I'll send you a Volvo pump down when I'm back later in May.
Have you rebuilt a 5 cylinder VP44?

Nope - Don't do TDI, damn direct injection it's just a silly fad that'll never catch on.
How difficult can it be - they are simple machines.
Do you know of an EDC15VM equipped VAG model that uses the VP44?
Scrap that, the pumps not as tunable as the VP37.
