Turiu nusikopinęs iš kažkokio forumo tokį aprašymą,bet neteko bandyt pačiam:

Q:
C5 A6 Alarm beeps.Anybody know if this is possible, along with anti-hijack on a C5 A6, 2001 X reg 2.4 V6?
There's nothing about it on the Ross Tech website.

A:
The anti hijack should be ECU 35 - comfort module
Then in the coding - function 07 add 32 to the number already there.
For the alarm to beep on locking, same module but add 1024 to the value.
