The Tiptronic has a detent that should keep it in place. If the
shifter is very easy to move to the right (without feeling the
detent), then something is broken or worn: (Sample from a VW)
Resting your hand on the shifter while turning left "can" cause the
shifter to move right... your hand/arm is applying a centrifugal
force to the right. You might think that you are not moving your
hand / arm, but you are.
If it truely is moving on its own, you will have to take the
shifter apart to investigate.
