The ABS module in a MK6 Jetta GLI can be a source of frustration when it fails. Replacing the module is often straightforward, but coding it correctly can be tricky. This article discusses a common issue encountered when replacing an ABS module in a MK6 GLI with VCDS and offers potential solutions.
Common MK6 GLI ABS Module Coding Issues with VCDS
Recently, a MK6 Jetta GLI owner experienced ABS module failure. The original module (part number: 1K0 907 379 BM) was replaced with a new one (part number: 1K0 907 379 BK). Attempting to input the original long coding string (A14B600C492800FD850C06E992220041A1180022) into the new module using VCDS proved unsuccessful. After further troubleshooting, the last two digits were removed from the coding string (A14B600C492800FD850C06E992220041A11800), and the module accepted the shortened code. However, this resulted in incorrect module programming.
The VCDS scan from before the original module failed provides valuable information about the vehicle’s state:

... (Full VCDS scan as provided in the original post) ...This scan reveals that several modules reported malfunctions, including the ABS module itself with a “Control Module – Electrical Error” (error code 16352). This error suggests a pre-existing issue within the ABS system before the module replacement. Additionally, there’s an “Implausible Data Received from ABS Control Module” error (U0415) in other modules, further indicating communication problems stemming from the faulty ABS module.
Possible Solutions for Incorrect MK6 GLI ABS Module Coding
The inability to correctly code the new ABS module suggests a potential incompatibility between the original and replacement modules, despite seemingly minor part number differences. The truncated coding string accepted by the new module likely doesn’t account for specific vehicle options and configurations.
Here are some steps to troubleshoot this issue:
-
Verify Coding String: Double-check the original long coding string against the vehicle’s factory specifications. Even a single incorrect digit can cause issues. Online resources and forums dedicated to VW/Audi vehicles can be helpful in finding the correct coding for your specific GLI.
-
VCDS Compatibility: Ensure that you are using the latest version of VCDS software. Older versions might not have the necessary updates for newer ABS modules.
-
Module Compatibility: Confirm that the replacement ABS module (1K0 907 379 BK) is indeed the correct part for your specific MK6 GLI model year and options. Subtle variations in trim levels can require different modules. Consulting a VW/Audi parts specialist is recommended.
-
Component Protection: VW/Audi vehicles often utilize component protection, which requires online dealer programming for certain modules. The replacement ABS module might need to be “married” to the car using dealer-level diagnostic tools.
-
Professional Help: If the above steps fail, seeking professional help from a VW/Audi specialist or dealership is the best course of action. They possess the expertise and equipment necessary to diagnose and resolve complex coding issues. Continuing to experiment with incorrect coding can potentially damage the new module.
Conclusion
Coding an ABS module in a MK6 GLI with VCDS can be challenging. While minor part number differences might seem insignificant, they can lead to coding incompatibilities. Always ensure you have the correct coding string and that the replacement module is compatible with your specific vehicle. If you encounter difficulties, consulting a professional is advisable to prevent further complications.
