Just a quick note from me on this (and sorry, it's in English)
I've been in contact with the guy who made the ID.4 Frunk mod, and I was given permission to try out the parts on the Enyaq - It's not a perfect match for the Enyaq, and it needs a bit of work to fit. Especially the container part needs to be redone, for a nice fit and also a better option than the cut-in-half Rubbermaid bucket.
So stay tuned, I'll be posting something once it's done
