I got to the last part of the assembly of unit no2 and whilst putting
on the top a dowel broke through. It pushed a big 'scab' of sawdust
wood out.
I tried to stick it back with super glue but no good....it is raised
slightly, although I put a precision flat surface on it weighed it down
with a microwave transformer. It looks like the dowel hole had been
drilled very close to the surface and the force offered by the mating
hole just pushed it through.

All their stuff is machined by robots, with all the holes on each piece
being drilled on each side in a single operation.
Possibly you didn't insert that particular dowel deep enough in the top
piece before inserting it in the side. Which is easy enough to do when
fatigue sets in. Then when you mate up the two pieces the protruding
dowel can get jammed sideways rather than pushed home in with the result
you experienced.

Ideally you should have sorted that out - ideally without bashing it too
hard which might have flattened the end - before gluing back the
detached piece which would have been possible with PVA. Before then
re-inserting the dowel and having another go..
