Dug up this old thread.
What about this cable and software? Looks good for all cars 2000-2010 and comes with INPA etc.

Its £36.99 but from a UK seller, there's lots at under £30 but they're all from Far east based sellers..
Also says it works on win7 too, but I have a workshop laptop on XP anyhow.
Any comments from you coding experts?
