69, there is not a lot of knowledge on this site about the dual clutch transmission. I'm sure it is a fine transmission, but it is quite complex. If you intend to service that transmission yourself, you are going to have to become an expert on it. It will require a lot of time and effort on your part, but that is fine if you have the interest and aptitude. It will be challenging, but rewarding. The first step is to download the service manual from this site and study it thoroughly. The manual is free to download.
