Me too. It's pretty intimidating. However, Ross-Tech has a wiki where you can read various how-tos. That is where I learned what I needed to do with the VAG-COM in order to release/engage the parking break motors. Once I saw it in action, I sort of chuckled at slick it operates.
Read the Ross-Tech wiki articles and it should explain what you need to do. If you have any questions about the steps, create a post. You'll get lots of help not only from me, but from the other members here, too.
