Was sent this few days ago. It’s a document that dwells a bit more into problems of VAG 7-speed DSG gearbox. In a bit more detail, than I was able to do and found before.
There is one interesting thing here, that I was not aware of before, and it is the knowledge of the problem. According to this document, VAG/VW knew about the problem, at the time I bought the car. They did not acknowledge this, when I was ordering my car. I asked them specifically about any problems with this gearbox, and they told me in a way, that it is “the best they made”.
