This guide provides a comprehensive list of VCDS modifications specifically for Audi S4 (B8 platform) vehicles. It consolidates information from various sources, including Audizine and AudiEnthusiasts forums, offering a concise and centralized resource for VCDS tweaks. This “Audizine Vcds How To” will walk you through each coding change.
Common Audi VCDS Tweaks:
- Disabling After-Wiper: Navigate to [09 – Cent. Elect.], [Coding – 07], then use the Long Coding Helper to access Byte 1, Bit 3. Uncheck this bit to deactivate the after-wipe function.
- Disabling Amber Corner Lights: In [09 – Cent. Elect.], [Coding – 07], access Long Coding Helper. Within Byte 10, Submodule 0, Bit 3, set the value to 0 to disable the amber side markers commonly found on US models.
- Disabling Key Warning (Keyless Models): Go to [46 – Central Conv.], [Coding – 07], and in the Long Coding Helper, uncheck Byte 9, Bit 7.
- Modifying LED Turn Signal Behavior: Within module [09 – Cent. Elect.], [Coding – 07], use the Long Coding Helper to adjust Byte 3. Bit 2 controls LED brightness with parking lights (1 = full brightness), while Bit 7 disables the LED strip DRLs with turn signals (1 = disabled).
- Disabling “Lights On” Warning: In [09 – Cent. Elect.], [Coding – 07], use the Long Coding Helper to set Byte 5, Bit 3 to 0. This disables the warning chime when opening the door with the lights on.
- Suppressing NAV/Phone Warnings While Driving: Access module [5F – Information Electr.], then go to Adaptation. Set both Channel 2 and Channel 3 to a value of 250.
- Disabling Seatbelt Chime: Navigate to module [17 – Instruments], [Coding – 07]. In the Long Coding Helper, set Byte 0, Bits 2-4 to inactive to disable the seatbelt chime.
Advanced VCDS Modifications:
-
Enabling Adaptive Brake Lights: In [46 – Comfort System], [Coding – 07], the Long Coding Helper allows activation of adaptive brake lights. Set Byte 8, Bit 0 to active (1) for flashing via turn signals, and Bit 1 to active (1) for flashing via brake lights.
-
Controlling Ambient Interior Lighting: Access the Hidden menu, navigate to [car], [carmenuoperation], [interior light], and set the value to 5. Also, enable the interior light within [car], [cardevicelist] in the Hidden menu and reset the MMI.
-
Displaying Gear Selection in DIS: Go to [02 – Auto Trans], [Adaptation – 10]. Select “Single Gear Display” in the channel dropdown, then choose “D on/S on” as the new value.
-
Activating Hill Hold Assist ‘Lite’: In module [03 – ABS brakes], gain Security Access (code provided by VCDS). Then, in [Coding – 07], use the Long Coding Helper to set Byte 1, Bit 6 to 1.
-
Enabling Auxiliary Ventilation: This requires modifications in two locations. First, in [5F – Information Electr.], [Coding – 07], set Byte 6, Bit 1 to 1 using the Long Coding Helper. Then, in the Hidden menu, enable Auxiliary Heating within [car], [cardevicelist]. Finally, in [08 – Auto HVAC], [Coding – 07], set both Byte 1, Bit 3 and Bit 4 to 1 via Long Coding Helper.
-
Enabling Battery Meter: Enable the Battery option in the Hidden menu under both [car], [cardevextdevicelist] and [car], [carmenuoperation], setting the latter to 5. Reset the MMI or, alternatively, add 16 to the existing value in Channel 39 within module [56 – Radio] under Adaptation.
This guide offers a starting point for VCDS modifications on your Audi S4. Remember to always back up your original coding before making changes and proceed with caution. Incorrect coding can potentially lead to malfunctions. Always refer to the official Ross-Tech documentation for the most accurate and up-to-date information.
