Your car would normally have a factory alarm build in which will be classed as antitheft alarm .
Now if you want to lock / unlock and have your indicators flash mirrors and headlights try rhis link ( https://www.audi-sport.net/xf/threads/activating-alarm-beep-by-vagcom.73485/ ) it wont be in the module 46 but have a look there as well as Module 09 as these were migrated as one in later models which i think started on the 2010 models , but stand corrected if some can tell me better.
I dont see you having a problem with the modules that allow this function as your car should have . Get an autoscan done PM me and i can compare my modules to yours as i have a 2010 model but 3dr if that helps.

Try given your car a good rocking once you come out off it and see if you hear an alarm if you do tgen its the antitheft factory fitted other than that like you i am lost . Did you read the rosstech as it explains why you would have this fault , might be an old fault thats not been cleared so clear the code and scan later to see if fault is still there.
Check this out ( https://www.audi-sport.net/xf/threads/alarm-horn.361473/ )

You’ll have an alarm but you’ll have a common issue that is a faulty alarm siren

I dont even have fuse installed in f17,i think that somebody coded alarm installed option so i can get horn notification when lock/unlock...
Can somebody just say is it possible to code this car a3 2010 to use standard car horn for beep when unlock/lock...
