Do yourself a favor, clear the codes and see what comes back after a few drive cycles. Just because the status is set doesn't mean it's current. When was the last time the whole status of the car was reset? I am not even sure if you can reset without The Volvo software.
It gives me the option to reset every module independently so I'll give that a shot.. I thought it was pretty cool for 80 bucks though. Definitely showed me more than I thought it would. I don't know when it was last reset, I've never done it.
