Dsg transmission dropped out of gear (like in neutral) several times over period of 1 week. Speeds ~20mph and 65 mph. Required drifting to safe area, stopping, and restarting car to get transmission to work. During failure the ep was illuminated, shifting between gears did nothing. Vw dealer reprogrammed tranny between failures. Have been using the shift mode for ~ 1week without issue. Saw several youtube videos of same problem - "false neutral". Numerous posts on tdiclub.
