Squid noise from the rear found

Hello, everybody.

I've been having such annoying squeaky noises from the rear of my A8 for some time now when I'm driving over ground waves.
On the right, on the left.

I first suspected the new springs, since since the installation of the KAW chassis this noise became louder, but were already there with the original springs at that time.

I then cleaned everything out in the trunk, took the compartment left to the CD changer, took the record up to the spare wheel.
Didn't help.

Then I oiled the boot lid on the joints with creep oil (it is now much easier to open and close) and I noticed that shortly before closing the lid squeaking noises arise.

Around the trunk cover holders are plastic covers clasped, in which each side a hose (central locking ?) and a cable (case interior lighting ? or taillights ?) are folded.

These cables/sleeves have jumped out of my plastic covers on both sides and rub with a protective rubber on the body and on the boot lid holders.

These rubbers make the annoying squeaky noises.
Cable and hoses again in the platik cover, already is quiet. Lovely.

Greetings

Martin
