@Genau - would you be able to find out exactly where that setting is in PIWIS? The forum would be eternally in your debt!After reading all the posts on this forum about the trunk beep volume reduction, I added it to the delivery checklist for my dealership to perform. The Taycan-trained master mechanic could not find anything about PIWIS configuration of this setting in the English-language service documentation. Fortunately, he is fluent in German, and was able to find some vague reference in the German documentation. That led him to the beep volume setting in PIWIS, with selections from 1 to 7, but no apparent way to save the setting. He was however able to completely turn it off. As an earlier post mentioned, beeping may still be enabled for an obstruction, but I haven't tested that.
