Does the 2011 Audi A5 have Bluetooth Audio?

There is no bluetooth Audio present on the 2011 AudiA5; Audi didn't start including this standard until their 2013 vehicles. Don't give up hope though, You can use an adapter to polyfill, as it were, and bring bluetooth Audio to Your vehicle. You can probably find the parts locally, but given the pandemic (at least, when I saw Your question, it was still going on) You might want to just order online. Amazon has the Bovee Wireless Car Kit for $89 with free shipping. This lets You stream music from Your Android phone, and is a simple plug and play that doesn't require any installation.
