I will see what I can find, but I'm not even sure it REALLY worked quite frankly as after the update the ECM went on the "blink" and I STILL do not have the car back because my Indy is so backed up with other cars. I had to get the ECM changed out to a new one and the ECM shop in Florida THINKS the ECM going bad had something to do with the DEF tank not updating itself when filled. Anyway, the shop got the software from some site online as I paid him $350 or the cost of the 1yr subscription to download it. When he loaded it...the VAG system told him that their was now 100K miles remaining before the need for a top up. Super strange if you ask me...Could you get some more details about the source of this software from your shop and post it? This is a widespread issue and dealers are unable to either solve it with a software patch or obtain replacement DEF tanks from VW. This would be invaluable information to post.
