Enabling the Coming Home (CH) and Leaving Home (LH) features on a Volkswagen Golf MK7 GTI can be a rewarding customization. However, even with VCDS (Vag-Com Diagnostic System), issues can arise. This article addresses common problems encountered when activating CH/LH on a Golf 6 platform, specifically focusing on a MK7 GTI retrofit.
After successfully installing and coding a rain and light sensor on a MK7 GTI, the CH/LH functions might not work as expected. This article will delve into possible coding discrepancies and solutions based on a user’s experience and provided VCDS autoscan. The user has already confirmed the rain/light sensor and auto switch functionality.
The user has provided several screenshots of their current VCDS coding in various modules:
A thorough review of these screenshots reveals that some critical coding adaptations for CH/LH might be missing or incorrect. While the time menu on the Discover Pro indicates partial success, the core functionality remains disabled. Possible areas to investigate include:
- Byte 18 in Module 09 (Central Electrics): Verify the correct bits are activated for CH/LH based on the installed hardware (e.g., rain/light sensor, auto headlight switch). Compare the coding with a known working configuration for a similar vehicle.
- Adaptation Channels in Module 09: Check the settings for “Coming Home Time” and “Leaving Home Time” to ensure they are configured appropriately. Values of zero will disable the functions. Also, verify settings related to activation triggers, such as unlocking/locking doors or using the remote.
- Module 5F (Information Electronics): This module might contain settings related to CH/LH behavior and interaction with other systems. Consult the VCDS label files for this module to identify relevant adaptation channels.
- Terminal 15 Delay: Ensure sufficient power is available after the ignition is turned off for the CH function to operate. This can be adjusted through coding or adaptation channels.
The provided autoscan confirms the presence of the necessary hardware, including the rain/light sensor (RLHS) in Module 09. No fault codes related to CH/LH were found. However, the absence of errors doesn’t guarantee correct coding. The autoscan provides detailed information about the installed modules and their software/hardware versions:
[Autoscan data as provided in the original post]This data is crucial for cross-referencing coding information and ensuring compatibility with available documentation.
By meticulously reviewing the VCDS coding in the suggested modules and comparing it to known good configurations, the issue with the CH/LH functionality can likely be resolved. Utilizing online forums and resources specific to VCDS coding and Golf MK7 modifications can provide further assistance. Using the provided autoscan information, compare the coding with a known working vehicle configuration for a similar setup. Double-check all coding changes and ensure a proper understanding of each modification before implementation.
