I was wondering if the ETKA is publicly available?? Can the common man purchase it??

Nope, not directly.

But VAG have now launched ETOS which you can buy which covers all VAG brands. Guess they figured there were so many copied versions of ETKA about they might aswell cash in on it.

ETOS?? same function as ETKA?? How much?? Thanks

Same function yes set out slightly different but same content.

We got our from a friendly SEAT dealer, not sure how much though im afraid.

why thank you for that , will talk to my dealer, see what he says.
