Coolant Loss - Please help. Pic inc.

[nobbley]

Hello,
Apologies I've searched for an answer to no avail


My Audi reported a loss of coolant today. Sure enough its below the minimum line.

There seems to be a loss/leak from the black rail in this picture.

I could have sworn this valve(?) should have a top on it.
Any suggestions?

Thank you. Looks like the seal ring is perished.

Yea the plastic bleed screw thats located in the pipe is pretty **** poor & guilty for leaking, it will snap if you even look @ it the wrong way & actually from the look of it the yours already has the head off it, I'd bin it for a metal bolt & sealing washer every time.
