We had an ur-quattro like this a few weeks ago, at the Area E meeting.

It turned out that it _had_ been bleed - but the wheels were not done in the 
proper order.  There's also a 'distribution valve' below the master cylinder, 
that has to be bleed separately.
 
On the ur-q, the order is:
 
     Master
     Distribution
     Left rear
     Right rear
     Left front
     Right front
 
Another possibility is that the locknut on the actuating rod from the clevis to 
the servo has worked loose.
