Just reading some info on the DSG on wikipedia and it mentions that when stationary it is recommended that N gear be engaged.
I always just keep it in D. Does anyone else put it in N and is it really recommended?
N position of the floor-mounted shift lever means that the transmission is in "neutral". Just like in P above, both clutch packs and all gear-sets are fully disengaged; however, the parking lock is disengaged. This position should be used when the motor vehicle is stationary for any period of time, such as red traffic lights, or waiting in a queue of stationary traffic. The DSG should not be kept in any of the other active gear modes, and be held in a stationary position on the footbrake for periods longer than a brief period - due to the clutches being held on the bite point.
