Your best choice for all information you will need is the factory service manual. (it's parts, diagnostics, service procedures, schedules, specifications, wiring diagrams, everything you need to fix your car.)where I might purchase a good service repair manual for the car.
Does anybody have experience or recommendations for this model?
It's called VIDA. You can purchase a subscription from volvo @ volvotechinfo.com. OR
You can easily find free on the internet - the stolen and hacked VIDA 2014d. That is info for up to 2015 year model cars and came on a double sided DVD. If you want to plug in and read codes and stuff -(everybody does) you will need a dice unit. The factory dice unit will be needed to download new software (you won't need to do that) or you can buy a clone. I spent $85 on a clone a few years ago. You will need a win 7pro CPU to install the software on - but any other "service/repair manual" is a waste of time. Others have win10 solutions or sell memory sticks with vida preinstalled also.
