We have a 2011 GTI with the DSG transmission at our household along with my 6MT 2012 135i.. The GTI behaves the same as what all you guys are describing. I want to say it's just the nature of dual clutch trannies right now and until everyone figures out how Ferrari and Lambo are doing it properly I think this will be a continuing issue.. That's just another reason I refuse to get an auto for now, I just don't feel the technology is there yet.
