The convenience of automatic door locking upon closing can significantly improve vehicle security and peace of mind. This feature, often referred to as “door slam locking,” can be enabled on many Volkswagen (VW) vehicles using VCDS (Vag-Com Diagnostic System), a powerful diagnostic and customization tool. This article clarifies the process and addresses a common point of confusion regarding module addressing within VCDS.
While some resources might incorrectly direct users to module 05 (Acc/Start Auth) for enabling door slam locking on VW MK7 models, the correct module is module B7 – Start System Interface. This discrepancy arises from differences in how various diagnostic tools, including VCDS and some other OBD-II scanners, identify and address control modules.
Understanding the Module Addressing Discrepancy
VCDS consistently identifies the Access/Start Authorization module at address hex05 across various MK7 models, including the Golf, GTI, Alltrack, and R. However, other diagnostic tools, may list this module at address hexB7. This difference doesn’t indicate a problem with either tool but rather reflects varying interpretations of the vehicle’s communication protocols. Crucially, for VCDS users, the correct target module for adjusting door slam locking remains hexB7 – Start System Interface.
Enabling Door Slam Locking with VCDS
To enable door slam locking on your VW using VCDS, follow these steps:
- Connect VCDS: Connect your VCDS interface to your vehicle’s OBD-II port and launch the VCDS software on your computer. Ensure proper communication is established.
- Select Control Module: Navigate to “Select Control Module” within the VCDS software.
- Enter Module Address: Input the address B7 to access the Start System Interface module.
- Access Long Coding: Select “Coding – 07” to enter the long coding helper.
- Modify Byte 2: Locate “Byte 2” within the long coding. Remember that byte numbering starts at 0.
- Enable Bit 4: Enable “Bit 4,” which corresponds to the “Locking for door slamming active” setting.
- Do It! Click on the “Do It!” button to save the changes and enable the door slam locking feature.
- Test Functionality: Test the functionality by closing your doors with moderate force. They should automatically lock.
Conclusion
Enabling door slam locking on your VW using VCDS is a straightforward process, but it’s essential to target the correct module address. Remember to use module B7 – Start System Interface, and enable bit 4 in byte 2 within the long coding. This simple modification can enhance your vehicle’s security and provide added convenience. Always refer to your specific vehicle’s documentation or consult with a qualified technician if you have any questions or concerns.
