I found this while just browsing the internet and it was mentioned on a forum but I have since forgotten which one. I have used this for changing adaptations and coding on my 2004 Audi A4 Ultrasport as well as my 2005 Audi A4 (B6). It works quite well and successfully adapted an RB8 cluster into my B6 replacing the RB4. Keys all adapted and working great. I haven't seen it mentioned here but I think it could come in use for a lot of us here as it doesn't require a Ross-Tech cable or any other expensive hardware. Just the de-facto FT232 blue KKL cable. There is a binary release for Windows, macOS, and linux. I have only tested with Windows but will be testing on my MacBook Air shortly.
