when i first take off for the day, from garage through stop and go in subdivision, my 2011 tdi sportwagen tends to surge and buck a little in first (it's automatic). once i get out on the 35mph road with no stops for awhile, it runs great. if i use more gas and hustle on into second more quickly, it seems to do better in the subdivision than if i putter along slowly. i was told i didn't need to 'warm up' the engine, just start driving. i did experiment with idling in the garage for a couple of minutes and that seems to help a little. i don't remember our other diesel doing this...i will be going in soon for a courtesy check but wanted to hear from you guys.
