Hi, I received two new rear air bags for my P38, can somebody tell me what are the soft rubber pipes, located in the top, or bottom, used for ?

Do you mean the plugs to kept dirt out until you install them and refit the air lines?

That may be the answer. They are a soft rubber plug with a round metal circlip on them, probably to stop the plug from being inadvertently pushed into the airbag.

Thanks for the answer, Chris. I now know that I don't have to unduly worry about them.
