One of the biggest known problems with the DSG...and does seem to affect 07 onwards.
There is actually a VW work note on DSG's mechatronic unit so you can ask you dealer to check the part code against the unit and if its within certain numbers they will do it. And I believe out of warranty if you push it. Most dealers will be aware of it.
My GTI was DSG, and was fine but my R32 had to have this done. Was plain awful. I was within warranty period so wasn't a quibble anyway.
However, personally I think the DSG doesn't work as brilliantly with the V6 as it does with the TFSI lumps. You really do have to learn how to drive it without being jerky. But in S and Manual it is sooooo much fun.
If anyone is worried, get it quickly checked by anyone with VAGCom or at the dealer. If it within the limits....get on the phone to Warranties Direct and sign up for a year. Then book it in with symptoms of jerkiness ;-)
