Hi,
I've been trying to get an audible horn, or beep to sound when I lock/unlock my Mk7 (with the key-fob) using a VCDS tweak. There's lots of stuff on the web in the Europe forums that confirms that the Mk 7 can do this, but I've been singularly unsuccessful in my many attempts. Most of the VCDS tweaks use the instructions below (or a variant of the instructions below).

Has anyone tried to get audio feedback when locking/unlocking their car? If so, how did you do it?

Alarm beep on lock / unlock (from VW GTI mk7 forum)
Go into [09] Central Electronics
Go into Secuity Access and enter 31347
Adaptation channels, and you are looking for:
(1)-Acknowledgement Signals -Akustische Rueckmeldung entriegen (un-lock acoustic feedback)
(2)-Acknowledgement Signals -Akustische Rueckmeldung verriegeln (lock acoustic feedback)
Set one or both to on if you wish.
Then set the following to "on"

(7)-Acknowledgement Signals -Menuesteuerung akustische Rueckmeldung (Acoustic lock menu)
This enables a menu setting in the "car" settings, "Locking" menu of the infotainment screen to set alarm chirp on or off when locking /unlocking the car and have the option to switch it on or off from the head unit.
