Got a 2016 with ACC and Front assist that had the signal cable error. After extensive diagnosis, of which the VW Service manual isn't much help, concluded the camera was the issue. Finally found a reasonably priced used one that I believe to be compatible, but it's from an older Audi A8. All the information I can find shows these systems to be somewhat identical, and sure enough it plugs in, codes and I was able to get it to allow the ACC to work again, once by fiddling with clearing codes in the image module and camera. However, it has a code that I cannot find any info on, and before I try to get it calibrated $$$, am trying to find out if the Audi Unit may have different software than the Touareg one as they are different part numbers. This could simply be to accommodate the different part number systems, or it could be significant. Again, the service manual has no info I can find as downloaded from erWin on codes.
Anyone have insight? Are the missing messages due to calibration (it did not say it needed calibration until after I reset adaptives in a hail mary attempt to get a result)
