Hello,
The best $35 ever spent with Audi ...
Official Factory Repair Information
You can have 24 hour access, complete wiring diagrams, component locations, repair manuals, body repair, TSBs etc...
The website allows you save or print to pdf files for later reference. Use your VIN number to find the exact / correct information you need.
If you have more than one Audi, you can download/print all the information you want, from 2020 and older!

I think it is totally worth it, better than other sources because, this is Audi, information straight from the manufacture!
Hope this helps,
