Should probably be more specifc.. The code from a failing ABS controller comes from a scan of the ABS module itself. The code translates to "Lost communication with the Instrument Cluster - Intermittent."
Normally, this would lead you to believe that the fault was with instrument cluster, but it's not. If this is the code you get, this is classic ABS controller failure, and it is only the electronics module that needs to be replaced. I believe Audi only sells the entire pump assembly for $1200-$1600. That is not what you want. Follow some others' suggestions to get only the electronics module at the places they recommended.
NOTE: If the codes indicate a sensor problem, then that is most likely what it is - a sensor issue.

if it's the pump / controller [which is under the hood by the washer
reservoir - looks like a proportioning valve] the scan tool will
likely come back with a 'can not communicate' error. the part is like
1800$ from audi. don't do that. =)
i had my abs pump rebuilt by http://www.autoecu.com/ - for 350 with a
5yr warranty. sorted my abs issue out. easy r+r - there are
instructions on their site.
it could be a sensor as well, those are very expensive [i paid 130 for
a front one] but easier to r+r than the controller.
Most of the evils of life arise from man's being unable to sit still in a room.
