Here you go -linky. I've no idea if the software is specific to cables but I would've thought all the sellers are selling the same cables. I followed the install steps in the Youtube vid posted above on a W7 x64 laptop and had no issues at all.
Normally I'd be with you all day long but I only want to change 3 or 4 stupid little things and my car is fully maintained
so it's not worth it.
I really don't wish to p!ss on the parade here but why are you guys going for these cheap leads for use with the full version of VCDS? The genuine article costs about £260-270, a little pricey perhaps, but it is the real deal with FULL support from Ross-Tech and it simply... works. I'm not an employee or have any vested interest in Ross-Tech but they are a genuine bunch of guys who have done an amazing job of unearthing the wonders of VW group car electronic wizardry. I bought my lead from Gendan more than two years ago and it has paid for itself over and over - through not having to go to a garage/dealer for a diagnostic check or helping a mate out. Come on folks, give them some real honest support!
