Anyway ... whatever. I have 7,8,9,10, and 11-speed, and I don't have problems with any of them. Sorry 'bout your problems, guys.
The initial batch of Army Armalite rifles had a problem with fouling up because they were machined to such tight tolerances. The AK47 in contrast had such bad tolerances that it could be thrown in mud and still work.
BMW cars are notorious for being tough to maintain. The tight tolerances explain a lot of it.
