What is this thing in my engine?

Hey everyone,

I'm very new to DIY car maintenance, but with each project am growing more interested in how my e39 engine works. My car has ~200K on it, and as old cars go, things break down. With a lot of help from these forums, I've learned about various parts through replacements and making small repairs.

For the sake curiosity and preparedness, do you recommend any other complete resources (books, websites, blogs, videos, etc) for learning about the e39 engine? I'm looking for something that covers the basic parts and can expand my general knowledge for diagnosing future issues.

I've come across big engine schematics, which are too large and complex to digest all at once. The forums have been useful, but they are a bit scattered, and appear to be more repair driven then a general "how-things-work" style. I don't know if what I'm asking for exists. This is, of course, why there are professional mechanics.


REGARDING THE PICTURES:

I was poking around earlier and came across a wire that looks like a tension cable for bicycle breaks... I took a few pictures, from a zoom-ed out perspective to close up. Anyone know what it is?


Thanks a lot

What's a "bicycle breaks?"

Get a copy of the Bentley E39 service manual, and a good scan tool. I have found the TIS helpful, too. You can sometimes find a copy on ebaY.

Google Search is your friend. It's amazing what you can find with an intelligent search term.

Where the arrow is pointing.

I'm not sure where I would start searching on google for this one.

Anything "cable" and e39 brings up things about power windows and opening the hood.
