It's a great tool. I originally purchased it several years ago to code a new battery on my A4 B8, and I've since learned by reading posts from other people's experiences.
There's a lot of questionable info regarding coding, especially the battery change on the A4 B8s and A5 B9. However be assured what I've posted is 100% working (apart from turning of the super annoying 'engine running' alert 😄).
And this is my way of paying forward, so thanks for the response. Google search captures most, but the Ross-Tech forum is definitely the best place to start.
