The little black elbow is in the diagram for the BMW oe battery.

You only need the elbow if you are using a battery that vents from the facilitates attaching the car's gray vent tube by giving it a solid right angle that is inserted into the battery's side vent hole...while allowing you to shove the battery back into the corner without pinching the car's vent tube.

If you have a top vented battery that requires the extension "vent kit" won't need the black elbow.

You can see the original black elbow in these pics below:


And it is BMW part # 61 21 1 377 835 (cost approx 52 from BMW dealer)...see #11 in the diagram below:

Sorry 'bout that. I "assumed" since it looked kinda used...but you know what they say about assumptions... And the kits usually come in a sealed again...I assumed...but was incorrect.

Here's one of the sealed "vent kits" that came with one of my Duralast's on my e34 525iT web page so this means a purchase date around 2005/2006:
