Coming Home lights, a convenient feature that illuminates your path as you approach your car, can often be activated using VCDS. This guide explores how to enable this feature, specifically focusing on the challenges and solutions for certain vehicle models. We’ll delve into specific adaptation channels and coding modifications necessary to activate Coming Home lights using VCDS.
Understanding Coming Home Light Activation with VCDS
VCDS allows access to a vehicle’s control modules, enabling customization of various features, including Coming Home lights. However, the process can vary depending on the car model and its specific configuration. One common approach involves adjusting settings within specific adaptation channels related to exterior lighting.
One user, “LasseTheDude,” suggests investigating the adaptation channel ENG141656-ENG115656-Außenlicht_uebergreifend-Coming Home Leuchten. This channel often controls the Coming Home light behavior, allowing users to select which lights (e.g., low beam, DRL, fog lights) should illuminate. Examining your vehicle’s current settings within this channel using VCDS is crucial before making any changes. The current setting might be “Low beam,” and while there might be options for DRL or fog lights, this depends on the specific car model.
Alternative Activation Methods Using VCDS
If the aforementioned adaptation channel doesn’t provide the desired DRL option for Coming Home, “LasseTheDude” proposes an alternative approach. This involves reverting all modifications within a specific coding spreadsheet (likely “Akkipen’s spreadsheet”) back to their original factory settings. Following this, only the settings for Leuchte6ABL LC5 (left-side low-beam lamp) and Leuchte7ABL RB1 (right-side low-beam lamp) should be adjusted.
This suggests a potential mismatch between the spreadsheet’s coding and the specific vehicle model in question, highlighting the importance of verifying compatibility before implementing any changes.
Specific Coding Adjustments for DRL Activation
The alternative method also includes specific modifications for activating DRLs as Coming Home lights:
Left-side DRL:
Leuchte4TFL LB4-Lasttyp 4: Change to>1 - LED Tagfahrlichtmodul Versorgung(currently not active).Leuchte4TFL LB4-Lichtfunktion A 4: Change to>Coming Home oder Leaving Home aktiv(currently not active).Leuchte4TFL LB4-Dimmwert AB 4: Change to>100(currently 0).
Right-side DRL:
Leuchte5 TFL RB32-Lasttyp 5: Change to>1 - LED Tagfahrlichtmodul Versorgung(currently not active).Leuchte5 TFL RB32-Lichtfunktion A 5: Change to>Coming Home oder Leaving Home aktiv(currently not active).Leuchte5 TFL RB32-Dimmwert AB 5: Change to>100(currently 0).
These adjustments aim to enable the DRL modules, assign the Coming/Leaving Home function to them, and set the dimming value to 100% for full brightness.
Conclusion
Activating Coming Home lights with VCDS can enhance convenience and safety. By understanding the relevant adaptation channels and coding modifications specific to your vehicle, you can successfully enable this feature. Remember to always back up your original coding before making any changes and proceed cautiously, verifying compatibility to avoid potential issues. If uncertainties arise, consult reputable VCDS forums or documentation for expert guidance tailored to your specific vehicle model.
