So any body can figure this part out?

Nope, it's a new car, no error messages or bad sensor anything. The closest i manage to find a clue about is in the link in the first post. Couldnt be buying a different tool just for a chirp (assuming it works) hence i'm head scratching here.

In that link the poster does say that they have only worked on one MLB A4 (and I couldn't see a date when that was posted), given that VAG/Audi have been changing a lot lately it's quite possible that the instructions are not applicable to your new A5.

I didn't spend a lot of time searching but I found this NAR 2019 A4 scan in our emails:

I can't share the scan directly but .. I wonder if the lack-of that Alarm horn / Subsystem 2 is the problem?

marble, I would keep an eye out for B9 A5 scans and see if any with factory beep also have a LIN alarm horn slave module in their scans.

Thanks Dana, i think you might be onto something. I wonder how to retrofit that part. whatever i googled looks like it's buried deep in the engine bay.
