Q379 Software Update

At 7,000 miles, at 1 year, I took my car to the dealer for his free 1 yr. service. The dealer, without notifying me, did the software upgrade Q379, which to my understanding effects the fuel regulator. After getting the car back I now have a annoying slight surge when driving at a steady speed around 2100 rpm. Before this the car was extremely smooth. If I am using the paddle shifters the surge goes away. Has anyone experienced problems after this software upgrade? 2013 Evoque, Petrol 6speed, USA spec.
