Hello to all those who know, and those who aspire to know.
I have now received my VCDS HEX-V2. Unfortunately, after reinstalling (directly downloaded from the shop) and searching online, I can't see any information about the access permissions (speech bubble) in the control units. With my old Q3, I was able to adjust all sorts of things using the older version. My new vehicle is an Audi Q4 Sportback 2023. First, I want to increase the number of comfort indicators, but I don't have access to control unit 19.
Adjust comfort blinker cycle.
STG19 - Diagnostic interface - Adjustment.
ENG174381-MAS07991-light_control-Comfort blinking: Set value - Adjust the value as desired (default: 3).
Here's another function of the STG19.
Activate the daytime running light as a turn signal.
STG 19 - Diagnostic interface _ Adjustment _
MAS09325-ENG116593-Daytime running light - Daytime running light - Continuous running light enabled. Set the value to "active" in addition to the parking light.
This function is also not accessible due to permission restrictions.
Deactivate seatbelt warning.
STG17 - Distribution board insert.
[Encoding-07] _
Byte 00: _
Bit 2-4: 00 - Seatbelt warning, off.
And now, the reason why I bought VCDS and have already ordered a used trailer hitch:
Aftermarket trailer hitch unlocking.
[STG19 - Diagnostic Interface]
Sure, here's the translation:
"Bill of materials" or "List of materials"
Add STG69 (SFD not required for ID Software version 3.0!).
[STG 10 - Parking Assist System II]
[Encoding-07] _
Byte 3:
Bit 0-1: Adjust value according to installation.
01, Trailer, Tow hitch (manually detachable)
02, Trailer, pivoting trailer hitch.
[STG 13 - Adaptive Cruise Control]
[Access permission - 16]
20103 _
[Encoding-07] _
Byte 01 _
Bit 7: Control module for towing sensor, 0 = not installed / 1 = installed.
[STG 17 - Switchboard]
[Encoding-07] _
Byte 0: _
Bit 3 Trailer, requires SFD.
[STG 3C - Lane Change Assist]
[Encoding-07] _
Bytes 4-5: Adjust the value according to the specific application.
10. ECU for draw bar, no ECU for draw bar.
ECU for draw bar, with draw bar ECU.
[STG 6C - Reverse camera]
[Encoding-07] _
Byte 2: _
Bit 0: equipment_ahk, installed.
[STG 6D - Rear cover]
[Encoding-07] _
Byte 01 _
Bit 7: Trailer support, 0 = not installed / 1 = installed.
[STG A5 - Apron Camera]
[Encoding-07] _
Byte 05 _
Bit 7: AAG, 0 = not coded / 1 = coded.
The access permission for the tailgate control unit (STG6D) is indicated by the speech bubble icon!
Please help me understand how I can code my functions.
Best regards, Reiny.

Hello Reiny,
Your vehicle is simply too new. VCDS is a tool that is not developed by the vehicle manufacturer, but by the company Ross-Tech. LLC.
I.e. Testing and development for new vehicles can only take place after they are released to the market.
You can help ensure your new vehicle is supported as quickly as possible by sending an email to support [at] ross-tech.com with the subject line "New car, labels missing".
Generally, it's always best to use the latest version of VCDS to avoid unnecessary complications, which is why I mentioned it in my previous post.
Best regards, Rainer.

Good evening, Reiny,
Your control units 17 & 19 are protected with SFD.
You can see this in your scan, specifically at the end of line 7 for each respective control unit.
VCID: xxxxxxxxxxxxxxxxxx -SFD
That means you first need to disable or have disabled the vehicle diagnostic protection. You will need the corresponding token for this.
You can read more about it here:
Okay, I understand. Please provide the German text you want me to translate into English. I will only provide the translation.
Best regards,
Michael.
