I, too, have both of these factory manuals, and both of them are pretty lame compared to good ole Ford and GM manuals. I can't seem to recall any instance where any fits or tolerances are called out, or any selective shims or bushings are noted, etc. Someone should bring suit to BMW for having the word "Troubleshooting" in the title of the electrical manual. IMHO, both of these manuals were published soley to prevent an independant from working on these cars, or more likely, to satisfy a legal requirement somewhere. An expensive factory manual should provide enough information for good ole Gervis to rebuild, no, blueprint the engine, transmission and rear end to better than factory specs. I know some will say that BMW, in their all-knowing wisdom, is protecting us from ourselves, or the info is too 'technical' to release to the general public, but that is a load of bullscheiss, mein friends.
