ACC disabled. How to reset sensors??

[SootyA82014]

My 2014 A8L TDI has the ACC auto cruise control disabled. I am unable to reset the values with my OBD eleven VAG app. Any suggestions?

Also I did not see this topic anywhere else in the form.

Josh.

I see you are in the USA, unlike most of the members here, so the software in your car may differ from those us in Europe. Is it possible there is some state or national requirement for the cruise control to be disabled by the manufaturer?

Hey! No no no. It worked before. I had it reset with my odb eleven VAG once. But now ODB vag wont let me reset.

Did you get this sorted in the end, it could be disabled due to faults in other systems most commonly brake and engine ecus. Am I correct in thinking your A8 uses a master and slave radar system with each located on different sides of the bumper and possibly a lidar in the center, I calibrated one of these years ago and at that time they had to be done in a set sequence and if one goes out of calibration it shuts all them down for safety
