Volkswagen vehicles often have hidden features and customizable settings that can be accessed and modified using VCDS (Vag-Com Diagnostic System). This comprehensive VCDS coding list for VW models provides a wealth of tweaks to personalize and enhance your driving experience. From comfort and convenience adjustments to performance optimizations, explore the possibilities below.
Enhancing Comfort and Convenience with VCDS Coding
Several VCDS coding modifications can significantly improve the comfort and convenience of your Volkswagen.
Heated Seat Memory
Enable your heated seats to remember your last setting. This eliminates the need to readjust the temperature every time you enter the vehicle. Access Control Unit 08 – HVAC Adaptation and activate “Retention of the seat heater level driver” and “Retention of the seat heater level passenger.”
Auto Close Windows When Raining
Automatically close your windows when rain is detected by the sensor. This convenient feature prevents water from entering your car if you forget to close the windows. Modify settings within Control Unit 09 – Central Electrics using Security Access Code 31347. Adjust “Access Control 2-Regenschliessen_ein_aus,” “Access Control 2-Regenschliessen_art,” and “Zugriffskontrolle 2-Menuesteuerung Regenschliessen.”
Mirror Dip in Reverse
Enable the passenger-side mirror to automatically dip when reversing, providing improved visibility of the curb and surrounding obstacles. Adjust settings in Control Unit 52 and Control Unit 09 using Security Access Code 31347.
Coming Home/Leaving Home Lighting Duration
Customize the duration your headlights remain on after you turn off the engine (Coming Home) or unlock the car (Leaving Home). Modify settings in Control Unit 09 – Central Electrics using Security Access Code 31347 and adjust the “Comfort illumination-Menueeinstellung Cominghome” value.
Closing Windows with Ignition Off
Operate your windows even after the ignition is off and the doors are open. This provides flexibility for ventilation and convenience. Adjust settings in Control Unit 09 – Central Electrics, Security Access 31347, Adaptation (13).
Performance and Handling Tweaks with VCDS
Starting Vibration Reduction
Deactivate the Starting Vibration Reduction system in Control Unit 03 – Brake Adaptation. This can improve launching and acceleration, particularly for performance-oriented driving.
Haldex All-Wheel-Drive Adjustment
Optimize your all-wheel-drive system’s behavior by selecting “Increased Traction” in the AWD Control Unit Adaptation Logic. This can enhance handling and provide a more permanent AWD feel.
XDS Differential Lock Adjustment
Fine-tune the aggressiveness of the XDS electronic differential lock in Control Unit 03 – ABS Adaptation. Choose from “Weak,” “Normal,” or “Hard” to tailor the system to your driving style.
Display and Instrumentation Customization
Oil Temperature Display in Cluster
Enable the display of engine oil temperature within the instrument cluster. This provides valuable information for monitoring engine health. Modify Control Unit 17 – Dashboard, Long Coding, Byte 10, Bit 01.
Refuel Amount in Cluster
See the amount of fuel added in liters displayed in the cluster after refueling. Adjust settings in Control Unit 17 – Dashboard, Long Coding, Byte 10, Bit 4.
Cluster Display Carbon Background
Change the instrument cluster background to a carbon fiber style for a sportier look. Modify the “Screen view” value in Control Unit 17 Adaptation.
Lap Timer Activation
Activate the Lap Timer functionality in the instrument cluster for track driving or performance testing. Modify settings in Control Unit 17 – Dashboard, Long Coding, Byte 1, Bit 3.
Conclusion
This VCDS coding list provides a starting point for exploring the hidden potential of your Volkswagen. Remember to research and understand each modification before implementing it. Always back up your original coding before making any changes. While these tweaks can enhance your VW, proceed with caution and consult reputable sources for detailed instructions and potential risks.
