Is my coolant expansion tank stuffed?

The metal piece showing can easily be pushed and pulled out of the expansion tank, I assume this metal piece showing is not meant to come out and that I need a new expansion tank.

Its the one that goes from the tank to the radiator (Small thin hose) as per pic.

Ohwell, hopefully CHCH Bmw have one in stock when I call them in the morning.

Its the original expansion tank from new, the give away is the factory hose clamp, so it was due to be changed anyway I guess.

Yes it needs to be replaced. The overflow nipple is not supposed to be separable from the expansion tank so it's broken.

Thanks for that, makes me feel better about it being broken, i didn't even try and take the hose off it either, only at the radiator end.. probably pulled on the hose a little when I re-attached it to the radiator, looks like it doesn't take much to break.

Yea could probably be glued if you had to run it for a short period but as a part that fails catastrophicaly its well worth replacing.
