I can only get my R56 clutch to be stiff and work properly when the pressure bleeder is attached and pressurized.
As soon as I pull off the pressure bleeder the clutch loses all stiffness and becomes very soft.
I've tried every method I can find to bleed properly and there aren't even small bubbles coming out.

Any help is appreciated!

 

you have to do it the same way you do brake lines....in case you dont know, try pump the clutch (car off/not running), keep foot pressed, open valve (a second person), foot still on and now pushing out fluid, close valve, depress, pump to feel stiffness, repeat if necessary.

 

keeping clutch depressed overnight will help too. use a piece of 2x4 wedged against seat. use a towel at the seat side to avoid depressions..

 

I tried your method @MiniToBe, which seemed to make the clutch harder, but it still won't disengage the transmission.
I kept trying it too, but it didn't work.

@Subw00er, I have kept the clutch down overnight and tested it and even for a few days and tested it and it doesn't seem to help...
