BMW 320d headlamp washer cover

[marka239]

Evening all. I have lost a headlamp washer cover on my 320d. I wonder if anyone can tell me he cheapest place to get a replacement (plus paint) and if it as easy as getting the tube out with some thin nose pliers and reattaching the cover on the end of the pipe.
Bmw forums are great for the problem but don't say the answers I'm after.

Thanks for your help.
Mark.
