As title says my s5 b8.5 2015 DSG on 29,000 miles is lurching forward sometimes when I come to a complete stop. Sometimes light jurk forward other times more violent. Feels like its holding onto last gear too long and jolting forward. Happens 5% of the time and cant see a correlation when it happens but seems to be in waves of happening a few times then doesnt for a while. Only had car 2 weeks and wondering what it could be? Anyone had any experience or clue?
