You say that you must use VIDA to read manufacturer reserved fault codes.
Whilst I would agree that VIDA has to be the diagnostic software of choice for 2014 and earlier Volvos, there are alternatives for the newer vehicles which the last publically available version of VIDA can't connect to, that do a pretty good job.
VDash for one is Volvo specific and free to read fault codes for personal use, although chargeable on a per use basis for performing other functions such as service resets and modifying ECU parameters.
My Launch MOT Pro can connect to all ECUs on my V40 and read fault codes, plot and log or graph sensor values, perform actuations, reset and calibrate functions etc. There are other alternatives intended for competent DIY mechanics or the independent motor trade with varying levels of connectivity and performance depending in part on how much you are prepared to pay.
Having said that, although I can't use VIDA to connect to my 2017 car, I still use it for all of the other reasons that you mention.
