The Audi B8.5 S4’s exterior lighting can be customized extensively using VCDS (VAG-COM) diagnostic software. This guide provides a comprehensive list of VCDS coding modifications specifically for the B8.5 S4’s exterior lights, enabling owners to personalize their vehicle’s appearance and functionality. This compilation gathers information from various online sources, offering a centralized resource for S4 enthusiasts.
Popular B8.5 S4 Exterior Lighting VCDS Tweaks
Below are some popular exterior lighting modifications achievable with VCDS coding:
- Disable Amber Corner Lights: Eliminate the amber corner lights for a cleaner, more modern look. Achieved by modifying Byte 10, Submodule 0, Bit 3 in Module 09 – Central Electrics.
- Disable Amber Side Markers: Deactivate the amber side markers, often preferred for aesthetic reasons. This modification also resides in Module 09 – Central Electrics, under Byte 10, Submodule 0, Bit 3.
- Enable DRLs (Daytime Running Lights): Activate or customize the Daytime Running Lights. Various options exist within Module 09 – Central Electrics, Byte 2, allowing DRL control via front side markers, high beams, fog lights, LEDs, side markers, and even tail lights.
- Enable Rear Tail Lights with DRLs: Illuminate the rear tail lights along with the DRLs for increased visibility. This can be adjusted in Module 09 – Central Electrics, Byte 2, Bit 7.
- Enable Euro Parking Lights: Activate the European-style parking lights, which utilize the turn signals at night. This is controlled in Module 09 – Central Electrics, Byte 9, Bit 0.
- Enable Front Turn Signals as Parking Lights: Utilize the front turn signals as parking lights for a unique aesthetic. Modify Byte 10, Bit 0 in Module 09 – Central Electrics. You can also enable these as DRLs by adjusting Byte 2, Bit 6 in the same module.
- Enable LEDs to Remain Bright for Parking Lights: Prevent dimming of LED parking lights for a more pronounced illumination. This is adjusted within Module 09 – Central Electrics, Byte 3, Bit 2.
- Adjust LED Brightness: Fine-tune the brightness of your LED lights to your preference. This requires Security Access to Module 09 – Central Electrics, and then adjusting Channel 3 in Adaptation.
- Enable Fog Lamp with Turn Signal: Activate the corresponding fog lamp when the turn signal is engaged for improved visibility during turns. This is controlled by Byte 4, Bit 0 in Module 09 – Central Electrics.
- Enable Independent Fog Light Control with High Beams: Allow independent operation of fog lights even when high beams are activated. Modify Byte 4, Bit 1 (Front) and Bit 2 (Rear) in Module 09 – Central Electrics.
Understanding VCDS Coding and its Risks
VCDS coding involves modifying the control modules of your vehicle’s systems. While offering extensive customization possibilities, it’s crucial to proceed with caution. Incorrect coding can potentially lead to malfunctions or damage to your vehicle’s electrical systems.
Before attempting any coding changes:
- Back up your existing coding: This allows you to revert to the original settings if any issues arise.
- Research thoroughly: Understand the specific function of each code before making changes.
- Consult reputable sources: Refer to Ross-Tech’s documentation and online forums dedicated to VCDS coding for accurate information.
This guide provides a starting point for exploring the exterior lighting customization options for your B8.5 S4. Always remember to prioritize safety and understanding before implementing any changes.
