Unlock/lock chirp or horn

If you have factory alarm then make sure last option in the "guide" is set to not active


Central electrics
- Adaptation
-- Acknowledgement Signals
--- Akustische Rueckmeldung global: Active
--- Menuesteuerung akustische Rueckmeldung: Active (Menu option in infotainment system)
--- Akustische Rueckmeldung entriegeln: Active (Unlock beep/chirp)
--- Akustische Rueckmeldung verriegeln: Active (Lock beep/chirp)
--- Rueckmeldung Signalhorn: Not active (Not active for alarm installed ||| Active for no alarm installed)
Press and hold green tick. it might ask for security code, enter 31347

And is the "Audible confirmation of central locking" / "Acoustic confirmation" enabled in the menu as shown above?
If that doesnt work, try changing

Lastly if it still doesnt work

What a bummer.
I have coded the exact mod on a 2016 Polo 6c however it had no factory alarm installed, and a 2016 Passat with factory alarm, and both of them works normally. the Passat with the alarm makes a chirping noise while the Polo used the regular horn.
I cant think of any other settings that we might have forgotten.

Edit.
might aswell change this back to "orginal"

Have you factory reset infotainment system inside the settings ? sometimes it helps

Hello,

I’ve still not given up on this, even though my efforts seem more futile with every failed attempt.

I’ve seen that video too and it got my hopes up that it would work on my car, too.

In another thread somewhere, maybe even on another forum cause I’ve read so much about this, someone had the issue that it would only work with one of the two car keys, so I got my spare key and tried again, even fully removing the feature in obd eleven to enable it again - no luck. I have reset all settings in the infotainment car menu as well, same outcome.

Now, I’m pretty much left with two more ideas, both of which I don’t know how to accomplish.

1) I’ve read somewhere that relearning your key to the car can help. I have absolutely no idea how to do that, though. Maybe someone here does?

2) I have maybe messed up some bits or bytes in the long coding. I’ve changed around quite a bit on my car and of course I did so without creating a backup first. I know, stupid. It’s been quite a while ago when I first started using OBDeleven on this car and I may have tried coding some stuff off stemei for the golf VI.
I don’t have a clue what I had changed and if I reverted it all after I had no success, and without a backup of factory settings I will probably never find out either - unless you know a way to factory reset the car.

Again, thanks for all your efforts and help!
