Enabling Pilot Assist and Adaptive Cruise Control

[IMAY2023]

Thanks! Hmm, and when you say, "The software itself on VIDA was $550 USD," was that the same IntelliSafe Assist package, or was it something different?

You are welcome. 
After the hydraulic unit is replaced, VIDA will show two different software reloads under the Hardware change TAB. 
One if them is BCM and the other one is the intelli safe assists. 
You should only order and install the intelli safe assists, that includes all the required software.  
Before doing that make sure an external power is connected to the car and voltage shows above 13 volts.  Otherwise VIDA will not install the software and most importantly, "Once you retrieved, do not cancel the installation,"  otherwise you will need to reorder the same software again and ask for a refund for the previous one. 
Let's say, you clicked on retrieve and then clicked on install after VIDA downloads the software. VIDA gave you error message "Connect external power". Even if you do not have one around,  Leave the VIDA as is. Make sure laptop is connected to power until you found one.  If you cancel the installation at that time or before hitting the install button, that's it. You will need to re order.  
Make sure the external power supply is not low on battery (if you are using a portable one because it takes a while to install.
