By chance I found your website offering a very promising software for car diagnostics. I've read your german part of your forum. I can read and understand german but writing good german is a bit more difficult.
I already downloaded the latest version and tested with my adapter: AGV4000exp rev. B with BIOS v1.3
For now I tested it on two cars. A Skoda Octavia (2000) and a Seat Ibiza (2010). The Skoda was only in K-line mode and the Seat was K-line and CAN.
Unfortunately I was not able to clear fault codes. And in CAN-mode some lines were made unreadable stating it was not available in the free edition.
I will post more findings. This is it for now.
The free edition being so limited makes me very hesitant to buy a full-version. Priced version are not offered yet, right?
Also your price model is not very clear to me. Basic and Pro and additional differences within Basic and Pro.
