Many Audi owners find the automatic tear wiping feature, designed to clear the headlights after washing, to be annoying. While a simple VCDS tweak can disable this on older C7 models, the process differs for C7.5 vehicles. This guide provides a clear solution for disabling tear wiping using VCDS specifically on C7.5 Audi models.
Disabling Tear Wiping on a C7.5 Audi using VCDS
The automatic headlight washer (tear wiping) can be deactivated within the Central Electrics module using VCDS. Here’s the step-by-step procedure:
- Connect VCDS: Connect your Ross-Tech VCDS interface to your vehicle’s OBD-II port and launch the VCDS software.
- Select Central Electrics: Navigate to [09 – Cent. Elect.].
- Access Coding: Go to [Coding – 07].
- Choose the Correct Control Module: In the dropdown menu, select the module ending with “x — 4G8 955 119 — WWS 57x”. This identifies the correct module for headlight washer control on C7.5 models.
- Open Long Coding Helper: Click on [Long Coding Helper].
- Modify Byte 1, Bit 3: Locate Byte 1 and change Bit 3.
- 1 = Active (Tear wiping enabled)
- 0 = Disabled (Tear wiping disabled) Set this bit to 0.
- Code and Confirm: Click “Do It!” to execute the coding change. Confirm the coding change was successful and clear any fault codes if necessary.
Important Considerations:
- Vehicle Compatibility: This procedure is specifically for C7.5 Audi models. Attempting this on other models may yield different results or potentially cause unintended consequences. Always double-check your vehicle’s exact module coding before making changes.
- Backup Existing Coding: Before making any changes, always save a backup of your existing coding. This allows you to revert back to the original settings if necessary.
- VCDS Version: Ensure your VCDS software is updated to the latest version for optimal compatibility and to access the most current coding information.
Conclusion
Disabling the tear wiping feature on your C7.5 Audi is a straightforward process with VCDS. By following these steps carefully, you can easily customize this setting to your preference. Remember to always back up your original coding before making changes. Enjoy a cleaner, less annoying headlight washing experience!
