I had a DSG on my 2010 Passat Wagon 2.0T (gas) and towed my Popup trailer weighing 1800lbs dry and closer to 2300lbs loaded with, battery, propane, water, and 3 Kayaks on roof. Never had any issues BUT always drove it in manual mode when towing otherwise it would hunt between gears with frequent shifts. Even on mountainous terrain it was fine. However my Passat was tuned to 250hp and 290lbs/ft tq so that helped.
