Nope, Leaning more and more toward starter brushes. Give the starter body (not the solenoid) a rap when it fails to crank.

Shock mount is very likely. It is #4 in the RealOem diagram. I'd plan to replace all the soft parts -- 11, 7, 3, 12, 13, 15 -- along with the mount.

Shock mounts are a trouble spot on a lot of BMWs. I've changed them a couple of times on my car in the last 10 years. The rubber fatigues and turns to mush. It's safe to drive, just noisy. Get some...

I thought you might have more resistance at the switch than 0.4 ohms. You might jiggle the key laterally as your do the test again and see if resistance jumps. Ignition switches get a lot of hard...

I'd use an ohmmeter and test resistance. I suspect resistance will be higher than it should be whether the starter can turn over or not. Why not test it in either state, start and no-start.
