When modifying settings in certain modules of Volkswagen, Audi, Seat, and Skoda vehicles using VCDS (Vag-Com Diagnostic System), you might encounter a message indicating an uninitialized module and requesting valid WSC (Workshop Code), Importer, and Equipment data. This often occurs when the module has a default or null WSC, such as “WSC 00020 999 00000.” This guide addresses the common question: what WSC and equipment number should you use in this situation?
VCDS typically offers three options:
-
Use Default Values (12345/123/12345): Selecting “Yes” allows VCDS to use these default values. However, there are reports of this leading to settings not being accepted, unintended changes, or the inability to revert to original settings, particularly with unofficial VCDS interfaces.
-
Try Current Module Values: Choosing “No” instructs VCDS to attempt using the existing values in the module. This might work in some modules but not others.
-
Manually Edit Values: Selecting “Cancel” returns you to the previous screen, enabling manual modification of the equipment number. A common suggestion is changing the “00000” to “00200,” which appears to be a factory default in various other vehicles.
The safest approach is to avoid using the default 12345/123/12345 option, especially with non-genuine VCDS interfaces. Using the existing module values (“No”) can be successful if they are valid. However, if the module genuinely lacks initialization, manually changing the equipment number to “00200” might be a viable solution. “00200” frequently represents a general or factory default equipment code.
It’s crucial to remember that coding changes are often permanent. Thorough research and understanding the specific module and coding procedure are vital before making any alterations. Incorrect coding can lead to unexpected vehicle behavior or even damage to the module. Consulting official documentation, reputable online forums dedicated to VCDS, or experienced professionals is strongly recommended before proceeding. This ensures informed decisions and minimizes the risk of irreversible modifications. Always prioritize a cautious approach when dealing with vehicle coding.
In conclusion, selecting “Cancel” and inputting “00200” for the equipment number might be the most stealthy and reliable solution for uninitialized modules with null WSC values. However, proceed with caution, research thoroughly, and seek expert advice if unsure. Understanding the potential consequences of incorrect coding is paramount.
