Enabling the automatic rain closing feature on your Volkswagen using VCDS can enhance convenience and protect your car’s interior. However, sometimes this feature doesn’t work as expected. This article will walk through troubleshooting steps for a 2015 MK7 GTI experiencing issues with Vcds Auto Close Windows and rain closing.
Common VCDS Rain Closing Setup Issues and Solutions
A common issue when setting up rain closing with VCDS is incorrect coding or adaptation channel settings. Let’s review the typical setup process and potential problems:
Adaptation Channels in Module 09 – Central Electronics
- Channel 15 (Access Control 2 – Regenschliessen_ein aus): This channel activates or deactivates the rain closing feature. Ensure it’s set to “Active.”
- Channel 16 (Access Control 2 – Regenschliessen_art): This channel defines the rain closing type. The setting “Permanent” should enable automatic closing.
- Channel 28 (Access Control 2 – Menuesteuerung Regenschliessen): This channel allows control of the rain closing feature through the car’s menu. It should be set to “Active.”
Potential Issue: Incorrect values in these adaptation channels can prevent rain closing from functioning. Double-check that each channel is set to the correct value using your VCDS software.
Coding in Module 09 – Central Electronics (Byte 0)
- Bit 2 (Rain Closing Active): This bit must be enabled for the rain closing function to work.
- Bit 1 (Rain Light Active): This bit enables automatic rain-sensing headlights. While not directly related to window closing, ensuring this is correctly set can help diagnose broader sensor issues.
Potential Issue: The provided coding change from 00A8DD to 06A8DD in Byte 0 should enable Bit 2. However, verify the entire coding string for your specific vehicle using a reliable source like the official Ross-Tech VCDS website to eliminate any potential coding errors. Different equipment levels and regional variations can affect the correct coding.
Additional Troubleshooting Steps
- Mirror and Window Reset: Performing a reset procedure after making changes with VCDS can sometimes resolve communication issues. Consult your vehicle’s owner’s manual for the correct reset procedure.
- Car Setup Menu: Ensure the rain closing option is checked within the car’s infotainment system settings.
- Environmental Conditions: Test the feature with the wiper stalk in the intermittent position and the light switch in the “Auto” position. Ensure there’s sufficient rainfall to trigger the sensor.
- Key Proximity: While the original post mentions the key being 20 feet away, try testing with the key closer to the vehicle to rule out any remote locking interference.
Rain/Light Sensor (RLS) Compatibility
The diagnostic scan reveals the RLS module (Slave 2, Subsystem 2) has the coding 06A8DD. While this appears correct based on the original post’s modification, it’s crucial to verify compatibility.
Potential Issue: An incompatible or faulty RLS could prevent rain closing from working. Using VCDS, compare the part number and software version of your RLS ( 5Q0 955 559 A) with the latest version listed for your specific vehicle model year in the Ross-Tech VCDS database. This will confirm compatibility and identify any available firmware updates for the RLS.
Conclusion
Troubleshooting VCDS auto close windows requires meticulous attention to detail. By systematically checking adaptation channels, coding, and RLS compatibility, you can identify and resolve the issue. If problems persist, consult the official Ross-Tech forums or a qualified Volkswagen technician for further assistance. Remember to always double-check coding and adaptation values with trusted sources before making changes to your vehicle’s control modules.
