Unknown component On My Z3
 

Hi,
Im looking for technical advice .

BMW z3 1.9 2001 Y806 GAH

Looking foreword towards the radiator, there is an cowling (air ? ) that sits right across the top of the radiator. On the right side of this there is a component that is attached to the underside of this cowling, right next to the washer tank This component had been pushed down from the cowling accidentally, exposing a concertina tube with a coiled spring inside. Cannot see it properly from picture as its underneath.

Would anyone know what this component is ?

grateful for any advice.
