The Audi B8 (A4/S4) platform offers a plethora of customization options hidden within its electronic control units (ECUs). Accessing these features requires a diagnostic tool like the VCDS (VAG-COM) interface. This guide compiles a comprehensive list of VCDS tweaks specifically for the Audi B8, empowering owners to personalize their driving experience.
Common VCDS Modifications for Audi B8
This compilation draws from various online resources and forums, centralizing information on VCDS modifications for the Audi B8. Remember to proceed with caution and at your own risk. While these modifications are generally safe, inaccuracies or improper execution could lead to unintended consequences. Always double-check coding procedures before implementation.
Lighting Adjustments
- Disable Amber Corner Lights: Eliminate the amber corner lights for a cleaner aesthetic. Access Module 09 (Cent. Elect.), Coding – 07, Long Coding Helper, Byte 10 Submodule 0 Bit 3, and set to 0.
- Disable Amber Side Markers: Deactivate amber side markers, common in US models. Module 09, Coding – 07, Long Coding Helper, Byte 10 Submodule 0 Bit 3, set to 0.
- Enable DRLs with Rear Taillights: Activate rear taillights along with daytime running lights (DRLs). Module 09, Coding – 07, Long Coding Helper, Byte 2 Bit 7, set to 1.
- Enable Euro Parking Lights: Activate parking lights that also function as turn signals at night. Module 09, Coding – 07, Long Coding Helper, Byte 9 Bit 0, set to 1.
- Adjust LED Brightness: Fine-tune the brightness of LED lights. Module 09, Security Access – 16 (Code: 20113), Adaptation – 10, Channel 3, adjust value between 5 and 100.
- Enable Front Turn Signals as Parking Lights: Utilize front turn signals as parking lights. Module 09, Coding-07, Long Coding Helper, Byte 10 Bit 0, set to 1; then Byte 2 Bit 6, set to 1 to enable as DRLs.
Convenience and Functionality
- Disable Seatbelt Chime: Deactivate the audible seatbelt warning chime. Module 17 (Instruments), Coding – 07, Long Coding Helper, Byte 0 Bit 2-4, set to inactive.
- Enable Automatic Hill Hold Assist ‘lite’: Activate a basic version of hill hold assist. Module 03 (ABS Brakes), Security Access – 16, Coding – 07, Long Coding Helper, Byte 1 Bit 6, set to 1. Refer to online resources for specific coding procedures.
- Enable Hidden Menu in MMI: Access the hidden MMI menu for advanced settings. Module 5F (Information Electr.), Adaptation – 10, Channel 6, change 0 to 1. Proceed with extreme caution in this menu.
- Enable Gauge Test/Needle Sweep: Activate the gauge test and needle sweep function. Module 17 (Instruments), Coding – 07, Long Coding Helper, Byte 1 Bit 0, check “Gauge Test/Needle Sweep active”.
- Enable Remote Operation Windows and Sunroof: Control windows and sunroof with the remote key fob. Module 46 (Cent. Conv.), Coding – 07, Long Coding Helper, Byte 2 Bit 2, set to 1.
- Disable After-wipe of Windscreen Wipers: Deactivate the after-wipe function of the windshield wipers. Module 09 (Cent. Elect.), Coding – 07, Long Coding Helper, find string “x 8K1 955 119 WWS xxxx”, Byte 1 Bit 3, uncheck (1 = active).
Display and Instrumentation
- Enable Battery Meter: Display the battery voltage in the MMI. Enable “Battery” in Hidden Menu (car -> cardevextdevicelist), then set “Battery” to 5 in Hidden Menu (car -> carmenuoperation). Alternatively, in Module 56 (Radio), Adaptation, Channel 39, add 16 to existing value. Requires MMI reset.
- Enable Lap Timer: Activate the lap timer function in the instrument cluster. Module 17 (Instruments), Coding – 07, Long Coding Helper, Byte 1 Bit 3, check “Lap Timer active.”
- Adjust Consumption in DIS: Calibrate the fuel consumption display in the Driver Information System (DIS). Module 17 (Instruments), Adaptation – 10, Channel 3, adjust the value. Consult online resources for calculation formulas based on your region (l/100km or MPG).
Important Considerations
Before attempting any VCDS modifications, it’s strongly advised to:
- Back up your existing coding.
- Thoroughly research each modification.
- Consult reputable sources and forums.
- Proceed step-by-step and double-check your work.
This guide provides a starting point for exploring VCDS modifications on your Audi B8. Always prioritize safety and responsible coding practices. Enjoy personalizing your Audi!
