Symptoms of Neutral Safety Switch/Position Switch Failure?

Hey all,

My car's been having a good rest in my garage ever since the transmission failsafe kicked in. Check this thread for more info

Anyway, last night I tried to drop the car at the local BMW indy shop despite the fact that gear's stuck at 5th, but I wasn't able to start the car. One click, that's it. Just like the symptom of dead starter. (Starter's been replaced few weeks ago)

Interesting thing is that when you wanna shift the gear from P to R/N/D without starting the engine, you need to put your key on acc2 position and depress the brake pedal, right? But this guy just moves freely. I don't even have to depress the brake pedal. Wtf.

My technician thinks that it's not mechanical problem, and judging by this new symptom, I'm suspecting that neutral safety switch(position switch) has failed, presumably caused all these issues. Does anybody know the symptoms of failing that part? Part# is 24107507818, #9 on this pic

Please let me know!
Thanks a zillion

One thing I can say is pending on the year of the car it could just b a software update at least that's what BMW said also u could jus by the sensor like 180$ drain tranny fluid remove pan n filter n replace it the reverse putting it together that's probably what I'll do its next to the bell housing accessible

Have you ever managed to find a solution to this problem. My 2002 318i Step Facelift is doing exactly the same thing.
