Engine management

When I wanted to have my new 9-5 he II checked the last time a few months ago, I was told that this would not be done as easily as before with the Tech 2, but rather a longer process with online connection to Saab (D ?), which would take hours. 2 questions: 1) How does it turn out then, if this is true and Saab D, is no longer, with the non-verification of a central system and the HANDLER guarantee, which then does not more is possible. (I don’t have a purchase contract with Saab, but with the car dealership, so that’s the first time!) 2) Is there not somewhere or some way to read out the currently working software and save it in case of all cases and play on it again if necessary? I had heard of a few clever people who should have created a kind of fire database for all kinds of drivers? Who knows more? Wolf
