i think all OBD2 pinouts are the same. Its supposed to be an industry
standard. Some of the protocols might be different, but the general OBD2
diagnostic protocol is the same. VW/Audi uses another protocol on top of
that as well, which can view the rest of the car's various systems and
modules.
If you want to save a few bux, check out www.obdtool.com . The tool works
with VAG-COM. My friend here at work builds these. I'm doing some of his
int'l sales now (to help lighten his work load).
