Was doing some searching, so just read through your posts again. We can assume you've eliminated the master cylinder and the ABS unit (no errors) as being the cause. I came across the following thread (post #4 in particular), and they mention about air still in the system. The mystery is your second quote above, how a 'few deep pushes' rectifies it. Note that the thread isn't about an Audi, but the principle should be the same:

BTW Did you run the procedure in VCDS to bleed the ABS unit through the NSF caliper?
