Allow me to educate you a little bit... VCDS versions are tied to years. So "VAG 12.12"... whatever TF that is... would be software we did in 2012. To that end, how would we know what would be needed 3 years down the road?
Our current version of VCDS is 20.4.2, and as the name suggest, this is software that was released in the dumpster fire year of 2020. Now our policy is "registered customers get free software updates for 1 year from date of purchase". Having said that, our current version of VCDS support hardware we sold back in 2003 and we have an unwritten policy of allowing our customers to update the software at no cost. So we have customers from 17 years ago getting free updates all these years. Our beloved customers can find the current version of VCDS here:
[sales pitch]
Our current generation of HEX series interfaces, HEX-V2 and HEX-NET, work with 1995 to current year model VW/Audi vehicles. With entry level price of $199 and top end price of $1299. For a large chunk of our enthusiast customer base, the $199 option is all they need. The best sales pitch I can offer up is to ask our customers.... is purchasing a kit from Ross-Tech worth the investment?
