Help with Audi A4 Radio Code

[NikolaClio]

Hello friends, I bought a 2006 Audi A4, and it didn’t have a radio in it, so I later bought an original one. The seller didn’t give me the radio code, so now my radio has no function at all. I kindly ask for your help, if anyone is able to send me the code.

Serial number: AUZ2Z3E2800211

Thank you in advance, and have a nice day.
