Mystery Part

Hi everyone, yet another mystery part. I had the housing off on the locking mechanism for the engine bonnet (F430) the other day and found this rubber piece loose sitting in the bottom. any ideas to what it is and where it goes

Look at your vacuum hoses

is it rubber or hard plastic? plastic maybe vacuum related
rubber maybe frame related

 

Looks like a check valve for a vacuum line. Likely got dropped and lost during some service.

 

thanks for all your input, don't think its plastic but feels more like hard rubber and it is solid, no hole through it

It's rubber. It's a filler plug for vacuum hoses.

I too found a couple in my car and I could not find where it belongs.

I can only assume its extra parts stuff from the factory left in the engine bay.

 

Brilliant, thank you, i can now rest easy

 

Solid rubber plugs like this can also be used to secure two items together.
