I very much doubt they would have implemented "hot keys" to bring up the information through the climate unit. They only really did this on the 8L and 8P as that was the only screen (apart from the radio, which you could also use to view the digital speed).
With the 8V having the MMI Screen the information would be displayed on there, and the options would be available through the menu (provided they are even available options).
I know previous cars such as the A8 show the battery level and Engine Oil temp but I think you'd struggle to get the likes of RPM on there.
