... not very well.
OK, source of info for DTCs... of course right here at TDI Club, just do a search for a given fault code and see what trails other members have blazed before you. I've had some good results doing this, and not so good results, but I've always gotten my moneys worth.
Ross Tech's wiki site is also filled to the brim with great info:
http://wiki.ross-tech.com
Pretty cut and dry to use.
I guess I should mention that Ross Tech also sponcers a forum over at VWVortex.com, and the Ross Tech crew is very active in that forum helping out it's customers. Can't say any eBay junk cable has ever supported anyone past payment.
My suggestion, jump over to Ross Tech's web site and look at this cable:
http://www.ross-tech.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=VCKII&Category_Code=VAGCOM
That cable will work with your car, works on VWs up to 2005. The price includes the full version of the software, newest version and you get free updates as they roll out. The eBay cables, if they work, use a version of the software that is several years old. The guys at Ross Tech put a lot back into the VW comminity than any other diagnostic vendor out there. You'll notice when the Ross Tech guys post, they are posting facts, not a sales pitch (which seems to be what I'm doing.....). Pretty much the law of the land is, Ross Tech's VCDS is the greatest.
'tis late, off to bed for me, busy day tomarrow.... I'm going to learn plumbing so I don't have to fork over $900.
