Watch what your technician is doin! That's what I did today!
It's possible to change the alarm setting to three different alarm sirens. My choice was US. That's sort of a police siren...well..comparable.
With the BMW Programming Terminal your work shop is also able to change the indication time of the indicators.
It sounds odd that your settings don't stick. I saw the technician clicking at two points. One was called somehow "Alarm indication ON/OFF" and the other one for the alarm sound was just called "US".
Anyway, that guy had to confirm these settings two times before he was able to send the changes to the bike. No probs so far beside the fact, that my board computer had been completely resettet after upgrading.
When I turn off the ignition now I hear a double beep after 30 seconds. Actually a warning "don't touch me"....
I bet it's not your bike with an issue, it might be your service technician the ole klotenzack
