Do you have a source that stocks the factory tools? I thought I had found what I needed; Baum Tools had the factory bushing tool on their web site (312260), but said they don't have it or even have any clue if it's available, but they are checking. So I'm still looking.
If I were you, I, Id get the AST tool:
VW, Mercedes, BMW, Volvo, Volkswagen, Audi, Ford, Dodge and other Tools for Specialty Applications
