I've seen this mentioned in the 'What do you love about your Polo' thread, but the info there is quite scarce.

As it's a handy feature to have I'd like to enable it on the Polo.

Would anyone here be able to offer some advise on specifically what is required?

Is the process detailed here accurate?
Dieselpower forum :: Zobrazit tma - Windows roll up with VDS-PRO

Where can one obtain the necessary OBD11 cable and VDS-pro software? Has anyone got this working over USB, or should I try to source an older serial cable?

Sorry for the zillion questions.
