Lewy, Pierce Automotive in Eaton has a vag-com. They are a service shop that specializes in Audi's. I learned about them through friends. They are right on Rte 20 near Bouckeville. 315-893-1844. I will be taking my car there for a vag-com tune-up soon. I just have to get all the codes I need from the posts here.
I went there last week, let them drive my S5, and they let me take their RS6 out for a spin. Very nice people.
