Went to a dealer, tech test drive and determined this just just downshifting because the car thinks I am going to do a rolling stop (not a complete stop) so it downshifts very late close to when I am going to stop ( he offered to reset the DSG but told him I can do that myself, know the procedures)I am having the same problem, just noticed recently on my 2010 TDI, it feels like the car jerks a little right before stopping....no change in RPM, it seems like the clutch isn't fully pressed sometimes and the car goes from Gear 2 to 1 right before it comes to a complete stop, seems like something to do with the clutch.
