Got my P8 back today with the replacement axle!! Everything seems to work fine. Now time for kudos to McDonald Volvo in Denver. The head of the dealership really went to bat for me and they worked hard to speed things up (axle had to come from Sweden). Head guy is working to get Volvo to show me some serious love for my trouble. Got software update while car in the shop. It felt wonderful to be behind the wheel again.
