What's that knob-looking doohickey under the seat?


Recommended Posts

NOT the preload adjuster--I know about that. This is a black knurled knob right next to the rear brake reservoir. Kinda loose but won't turn. What the hell IS that thing?

I'm willing to bet that it is the cover on the port for the diagnostic computer to plug into. Look to see if there are wires coming out from under it.

It may not be a knob at all. It might be the end of the bleeder hose for the clutch, depending on if you have a hydraulic clutch, you are referring to a BMW, and it is about 5/8" in diameter.
