No indicator flash when locking

Only had my Q5 a few weeks and getting along fine with it. However, I have a few minor niggles which I wondered if I could change:

-Making the Start/Stop system remember its last state rather than being ON at every start up.

-Have the auto handbrake automatically come on when the ignition is turned off.

-Having the option to turn on an audible signal when locking the car (having it as an option in case I decide I dont want it anymore 🤣).

-And finally, having the indicators flash once when locking. They already flash twice when unlocking so just thought (after reading about coding) that I'd be able to alter this.

So today I borrowed a work colleagues Carly. I've failed on all counts! The first one I thought I'd managed to disable the S/S but haven't. The 2nd and 3rd I couldn't find anyway in Carly to do them. But the fourth one, and the main reason for my topic, I'm wondering if there's an issue which is stopping the lock flash? I had the Carly options set as flash once for lock, twice for unlock but the lock still doesn't flash.

Whilst I have the Carly, I ran a vehicle check and it's showing 2 issues. One with "GSM antenna 2 break" and the other one showing as an issue with the Left Hand Rear Door - Central locking switch implausible signal, error code B122D29.

Does anybody know if this issue could be the reason for the indicators not flashing when I lock it? I've checked all the doors are locked when I lock it and they are.

Any help/suggestions muchly appreciated.
