If you get the 'Rheingold' software also known as ISTA/D that basically has the service manual "built in" electronically including service procedures, repair procedures with diagrams AND diagnostics capability ; it's the same software the dealership uses and includes torque specs and everything.
I don't know if there is a PDF download available anymore (I never found it).
Note: I find the 'INPA' diagnostics software faster and more useful in a lot of cases, I think having both INPA and ISTA/D are useful.
