interesting video, but that design is not what I found in the starter on my 2001 3.0i when I took it apart (nothing wrong, mostly for fun, and to tune it up and replace brushes when I had easy access to it). My Bosch starter looks and works more like this: https://www.youtube.com/watch?v=Sf6LqYBLljs which may help in understanding how it is supposed to work, and also what might be wrong. To be clear, the main difference between the two is that on the Bosch starter, the solenoid - in addition to of course closing the electrical contacts, acting as a relay - actuates a yoke that pushes the gear toward the flywheel. Very different vs. the interesting use of rotational inertia and left handed threads on the shaft by that other one.

I just wanted to provide an accurate schematic / video of how my Bosch starter (and likely how all E53 starters) works, since it's different than the one in the other video. Really interesting how the non-Bosch one relies on the rotational inertia and threads for actuation. The guy said it came out of a Honda, not sure who made it. Very different from how the Bosch works.

Could be a worn out ring gear, and that would match your symptoms. And that's a bad time. Remove your starter, spin the engine with a bar on the crank pulley and inspect the flywheel teeth. If they're good, replace the starter.

Also note my rust-preventive oil layer in the photo. If it were my car, with a general problem with the starter not spinning, I would do more electrical troubleshooting first - e.g., bypassing things that could be causing the failure without it actually being the starter that is at fault. When I "rebuilt" (not much really needed) my starter when I had easy access to it, I really did not do much. Cleaned out some debris from brushes, renewed grease, replaced brushes (although existing ones had 70% left at about 186k miles), and cleaned up some electrical contact surfaces. No signs at all of anything deteriorating.
