I would expect that just to be a vent behind the diaphragm to reduce "back pressure" so maybe a small amount of air when actuated as the diaphragm moves?
Let us know what you eventually determine the failure mode to be and will get that Quattroworld FAQ post updated. Not seen anything other than torn linkage boot issues and pump failures before. Photos always good ;-)
That 'Nothing on here' port would be for a cabriolet, for some reason they run the pump in reverse, so would use vac to open, rather than vac to close as on yours.
