If you talk to an OPC with the VIN number they can print the build details for you. I got four pages of build details on my Cayenne. Not a certificate but useful.
You can also stuttcars.com, it will cost you €15,but it's done almost by return. I did it this week for my car a 2017 991 Turbo S and they returned a full build list which ran to 109option/build codes.
