Just to add more info to my previous posts on this subject:
After getting the updated adaptive steering software installed, and regaining that functionality, I noticed two DTC codes in Forscan, related to the Steering Angle Sensor not being initialized / calibrated. Brought car back to dealer, and they saw the codes, reset the SASM Trim, and codes cleared. It also seems to have brought the adaptive "feel" back to the steering as well.
So.... either get Forscan to view your DTC codes, or make sure that there is an indication on your paper work that they performed the steering angle sensor calibration, and checked for any DTC codes, post install.
