Yesterday I learned from the workshop of my trust that Audi can no longer supply spare parts

Now I do not want to "throw away" my A8. As I read here, I share this fate with others.
So I'm looking this way. Does anyone still have a new 4D0 422 893 B extension hose lying around or does a source know where I could still get it?
If necessary, would I also take a well-preserved used one?
Greetings Dieter
