My Service Rep called me a moment ago and said they did the latest update for the TSB 12B37 campaign which addresses some issues regarding the DCT tranny, etc.
However they were still working on the noise issue and said he wasn't sure if it would be ready by the time I got there. He said, first of all it was difficult to locate the noise but that they have it torn down and if its not ready by the time I come to get it that they would put me in a loaner.
I will try to find out more today when I get there in a couple hours. Maybe they've found something that others were never able to find. Fingers crossed!
