RT LC, help me identify this part please

[vteec]

hi,

I found this white plastic tube like cover under the pillion seat of my RT LC, running around.
I cannot identify where it belongs to.
And I do not think it is standard bmw.
could it be it was dropped by the garage during a service or something please?

Is it a sample bottle?
