The CEM has a security code that must be presented by software attempting to change any of its programmed settings. The code is stored on Volvo's server and accessed through VIDA as necessary. "Decoding" by VDash is basically a brute force attack, in that (tens of) thousands of possible codes are thrown at it until they find the one that works. But you don't get to see or be given that code. It is stored on the VDash servers against your car's VIN and can only be used to carry out reprogramming or software changes through that software.
So it won't allow you to use a BSR or any other non VDash software/device unless you also use that company's methods to enable programming.
