Enabling automatic mirror folding on your Volkswagen vehicle adds convenience and can protect your mirrors from damage. This guide provides a comprehensive walkthrough of how to activate this feature using VCDS (Vag-Com Diagnostic System). We’ll cover two primary methods: using Adaptation channels and Long Coding.
Method 1: Adaptation with VCDS
This method involves adjusting specific adaptation channels within your vehicle’s door electronics module.
-
Connect and Access Module 42: Connect your VCDS interface to your vehicle’s OBD-II port and launch the software. Navigate to module 42 – Door Elect, Driver Side.
-
Security Access: Enter “Security Access – 16”. Input the security code: 04354 and click “Do It!”.
-
Adaptation – 10: Return to the previous menu and select “Adaptation – 10”.
-
Locate ENG109285: Scroll down the list and find the adaptation channel labeled “ENG109285-System_Parameter_14”.
-
Modify the Value: The current value will be a hexadecimal string. You’ll need to change the second pair of characters (octet) to either “E9” or “E5”. For example, if the original value is “74E01EE40000000000000000000000”, you would change it to “74E91EE40000000000000000000000” or “74E51EE40000000000000000000000”.
- E5: Mirrors will fold when the lock button is held and unfold when the engine is started.
- E9: Mirrors will fold when the lock button is held and unfold when the driver’s door is opened.
-
Save Changes: Click “Do It!” to save the new adaptation value.
-
Fault Code Check: After making changes, it’s recommended to check for any fault codes and clear them if necessary.
Method 2: Long Coding with VCDS
This method involves modifying the Long Coding within module 42. Proceed with caution when using Long Coding, as incorrect changes can potentially cause issues.
-
Access Module 42 and Coding: Navigate to module 42 – Door Elect, Driver Side, and select “Coding – 07”.
-
Long Coding Helper: Click “Long Coding Helper”. This will display a breakdown of the coding bytes.
-
Analyze Existing Coding: Carefully review your current coding. Pay close attention to Byte 0, Byte 1, and Byte 2. The original post provides examples of how these bytes might look and what specific bits represent (e.g., start/stop system, folding mirrors, exit warning lights).
-
Modify Byte 0: Based on the original post, changing Byte 0 from “02” to “32” might enable one-touch mirror folding. However, this modification is experimental and could have unintended consequences. Proceed with extreme caution and research thoroughly before making changes to untested bits.
-
Mirror Fold-In Bits: The Long Coding Helper should have options for “Mirror fold-in: comfort” in Bit 4 and Bit 5. Ensure these are activated.
Enabling Convenience Features in MFD
After completing either coding method:
-
Access MFD Convenience Menu: Go to your Multi-Function Display (MFD) and access the Convenience menu.
-
Window Operation Settings: Ensure the “Window Operation” setting is set to either “Driver” or “All”. This allows control of the windows and mirrors through the key fob.
-
Test Functionality: Test the auto-folding feature by holding down the lock button on your key fob. Your mirrors should fold in. Unlock the car to confirm they unfold according to your chosen setting (engine start or driver door open).
This guide provides detailed steps for enabling Vcds Auto Fold Mirror functionality. Always exercise caution when modifying your vehicle’s coding and consult reputable sources for specific instructions related to your car model and year. Remember to back up your original coding before making any changes.
