A4 ABS help- last call or car gets crushed.

[Bob]

Im about ready to crush this POS unless someone has any greaet 
suggestions.  its a 98 2.8 with about 80K on it.  This past summer the 
ABS light came on so they took off all the sensors and cleaned the crap 
off them. No help. VAG-COM said "unable to communicate with ABS 
controller" Ok its shot, fine.  Got the upgraded one and installed it, 
bled the system etc. Brakes function but the ABS now kicks in at the 
slightest thing. Even on flat dry surfaces. It is most annoying. I wound 
up unplugging the ABS controller again. the beep and light is less 
annoying.  VAG COM says it can now communicate with it and isnt showing 
any issues.

Any suggestions appreciated, or come pick up a free A4!
