This car squats and raises much less than my 240D when going from reverse to neutral to drive.
But I don't think that's lash.
In park I cannot turn the driveshaft by hand even just a slight fraction.
My thinking is, in neutral, feel how much slop is in the pinion, either rotationally or side to side. Probably easier if the wheels are locked. Not sure if the manual lists limits.
