Keep on bleeding.
Do the fronts first, passenger side preferably, then the rears.
If its still soft, then look for the leak, cos its either got to be air in the system or a leaky system.

sounds like the abs kicking in strangely? try with the abs dissabled see how it feels? (not sure if theres a fuse for it, if not just unplug one of the front roadwheel speed sensors from the arch).

Aslo make sue your spring retainers for the calipers are on correctly. If they're sat in front of the lip instead of behind it they will push the caliper sideways. Then when you brake the caliper starts kicking and can be heard as a knocking noise. It also pushes the pads off the disc and causes a spongy pedal.
