Yea, mine too.  Same thing.  If I am persistent, It will usually take.  I have not looked into this but I am under the impression that this system is somehow working with vacuum pressure.   Is this true? anyone.

Todd,
This happens frequently with both my jetta and westy, if I keep trying it
usually will take and keep the pedal down, it also intermittantly disengages
without touching the brake or clutch.
I have learned to live with it.
