[s-cars] Misfire Diagnostic Help

Mon Jan 16 10:46:07 PST 2012

Yes, those cables should work fine Mike.  Download the VAG-COM lite  
software from ross-tech.com for free and you are ready to go.   The  
windows XP laptops work best IMO, but likely because I bought a cheap  
netbook to use with my full version.  This system works fine for the  
UrS cars even without paying the activation/registration fee.  You can  
see the comparison on the web site to see what you get with each  
version to judge whether it is worth the trouble to activate.  You  
don't get much support with the lite program either way, but you  
shouldn't need anything unless  you activate and then your hard drive  
fails.

I know this stuff looks so cheap and it takes a long time to get it,  
and these people don't speak much english and so don't answer  
questions, but they are the real deal.  Just don't go getting the idea  
that paying more will get you something better.  If you have a 2005 or  
later VW/Audi/Lambo/Bugatti, you need the full featured version  
directly from ross-tech.  But, for the UrS, this lite system gives you  
almost as much as the full system.

JC on the quattroworld forum travels frequently to China on business  
and knows a lot more about the various suppliers of these cables.  His  
email is linked to his screen name there if you want more info.  My  
thoughts are you won't be investing so much money here that you need  
to worry too much.
