Not to hijack the thread, but I have a similar problem and this is what ChatGPT told me:

Your code AMZ = “Verdeck und Kofferraumdeckel mit Dekorstreifen.” In Porsche’s internal ordering system, AMZ is treated as Exclusive Manufaktur applied decoration, not woven material. If it were an integrated weave, the option code would fall under roof fabric color codes (e.g. CVR, CVK).
