I understand what you are trying to say but my argument would be the sheer number of complaints pertaining to the 7 speed versus the 6 with different designs point to an issue more along the lines of mechanical design.
Not sure why you think it should occur in a short space of time either. Surely the varying distances and the amount of traffic encountered would make the times different as well. Basically what you should see are complaints over a long period and the various dsg related threads on watercooled Australia alone point to this over a four+ year period. Similar threads exist in China, Malaysia, Singapore, Russia and more for all VAG brands. This level of consistency in juddering complaints is not seen for other transmissions used by the VAG Group even over the last 5 to 10 years. I refuse to believe dq200 drivers as a group push their cars in different, more stressful ways than dq250 drivers which to me seems to be what you are trying to say? Not sure, correct me if I interpreted what you are saying incorrectly.
Not sure why you choose the word failure as well as we all know that juddering doesn't necessarily mean failure with respect to the clutches. It comes and goes but generally vehicle can still be driven but not comfortably.
Basically my point was that if the issue was really driver related VAG would have put instructions on the proper way to use the tranny as they write the manual to be pretty idiot proof.
Just out of curiosity, do you drive a DQ200 equipped vehicle regularly?
