200 20V diagnostic ports are shown here with the blue un-used.
I used Vag-Com for the pulling of codes. At Ross-Tech.com there is a
community list where people in your area are listed to help others out with
the "scan" tool.

like a lister said, borrow once for free..... otherwise buy the tool. (in
this case a diagnostic tool from your favorite vendor)
> Yes, you can run diagnostic and check for stored codes without using a

> Basically, to run the tests, put a jumper from the L line (brown
