Guys: if you'd like to have a copy of the actual Vehicle Build data for your own RS3 (or any other Audi/VW vehicle, I guess?) then your local dealer should be able to provide, mine did.
Mine is a 5-page document and includes: Vehicle ID No., Sales model, Engine code, Description, Production and Delivery dates, Type approval numbers (so interesting for me!)
PLUS: Dealership number, Importer ref, Warranty period, etc.
AND of great interest: ALL of the PR Code numbers with Descriptions of each and every element included in your particular vehicle.
ALL interesting stuff, and worth adding to your own vehicle documentation.
The source address at your dealership is as follows:
ADDING your own VIN, of course.
Stafford Audi did this for me; thanks to Stafford Audi...
