Wheels turn in neutral
I just got my car running today. It's up on jackstands with no wheels on at the moment. When I was standing outside the car, I noticed the rear rotors were slowly turning, even though the car was in neutral. Any idea what would cause this? My first thought was clutch, but then I remambered the trans was still in neutral. It's an S4 n/a, all stock, if it matters.

its your spigot bearing dragging lightly on the input shaft of the gearbox
- normal enough
the bearing is often installed without the oil seal ( provided separately )
which leads to premature failure , often heating the bearing to gall it enough onto the shaft to make funky noises in neutral
( and eventually lead to the clutch having trouble seemingly disengaging, its actually OK, but the spigot is nearly welded on )
carry on, not worth looking at till clutch goes, then change out spigot

Yup... The input shaft is turning and that pushes the oil in the tranny around. The oil pushes the output shaft just enough to turn the driveshaft. You could probably grab it and stop it.
Back in the day, my father had a car that leaked transmission oil. Rather than fix the problem (It was a beater.) he decided to replace the 80w90 with some thicker 140 weight gear oil...
The car would move forward in neutral without the brakes being pressed.
He changed that back really quick.
