ACC front sensor.
I replaced an ACC sensor unit on a 2009 A8L. Everthing went great, Unit powered up, communicated through the controller to the VCDS, and accepted all changes from the recalibration. Then,
on the test drive, at speed, the car reported "ACC Blocked". I've re-calibrated, and it happened again. It seems like although all indications of the settings being stored, they do not seem to take once on the road.
