Thats great news, mine is currently sat at the dealers awaiting its new DSG unit today. They first of all tried the reset, worked for a short period, then it just was not smooth enough so, they said, 'we know th eunits fail, you know the units fail' so lets just get it changed.
They have stated that they fit on average 1 DSG unit per week under warranty replacement.
So glad you have yours sorted, you can now enjoy it
