after I have just heard that the Saarland has formally deposited a request for membership of Switzerland at the Saarbrücken Prunksitzung, I dare to ask for advice again...

For a few days now, brawls and rattles from the rear while driving over rougher bumps. I mean, it's coming out of the trunk or the back cover somewhere. I have now removed everything from the trunk (even the spare wheel and the tool)... Nothing there, it's still clapping. Then I screwed down the rear flap interior cover - and I thought I had the troublemaker: This weird switch that Audi installed to turn on the lighting was clapping around... The thing stuck, but nothing there. I checked the battery shaft, too, there's nothing. The number frame is also taptopp fixed. But there's something in there that's leaking to the tin somewhere in the back... But I don't think it's... this is driving me crazy

Does anyone know anything like that - and have they discovered the troublemaker? Or does anyone else have ideas where to look?
Thank you, but thank you very much.

... was hat der Vorbesitzer bloss gemacht? Und wie kommt es dorthin?) hab' dort nix gefunden. Das ganze wieder reingeschraubt und nochmals fix in den Kofferraum geschaut... und dann hat's endlichendlichendlich "KLICK" gemacht bei mir... DAS WARNDREIECK!!! Das Ding mal rausgenommen und ne kleine Probefahrt gemacht... and finally: Die langersehnte standesgemässe Ruhe ist wieder in den A8 zurückgekehrt.
