If you’re struggling with a persistent VCDS code, you’re not alone. Many VW and Audi owners have found themselves in similar situations, often turning to online forums like VWVortex for help. This article summarizes common advice found on VWVortex regarding recurring Diagnostic Trouble Codes (DTCs) after clearing them with VCDS.
Common Advice for Recurring DTCs
A typical recommendation on VWVortex for dealing with stubborn codes involves a systematic approach:
- Clear All DTCs: Start by clearing all Diagnostic Trouble Codes using VCDS. You can do this either within the specific module showing the fault or by using the “Clear all DTCs” function after an Auto-Scan. This function clears codes across all modules. Clearing codes in the engine module, with or without existing DTCs, will reset readiness and trim. Other modules will not have readiness or trim reset unless there’s a DTC present.
- Cycle the Key and Drive: After clearing the codes, cycle the ignition key, and take the car for a drive. This allows the vehicle’s systems to run through their checks and potentially re-register the fault if it’s a persistent issue. Activating various components, like the front and rear door controls, can also help trigger the fault.
- Re-scan: After the drive, perform another Auto-Scan with VCDS to see which codes have returned. This information is crucial for diagnosing the underlying problem.
Understanding Readiness Monitors and Inspections
Clearing codes in the engine module resets readiness monitors, which can impact vehicle inspections. Regulations regarding readiness monitors vary by location. Some areas allow one or two incomplete monitors to pass, while others require all monitors to be set. Consult your local regulations for specific requirements.
Exercise Caution When Clearing Codes
While clearing codes is a valuable diagnostic step, it’s important to proceed with caution. Certain codes, such as those related to airbags or ABS, should be investigated thoroughly before clearing. Clearing a code related to a short circuit could potentially trigger unintended airbag deployment or exacerbate existing issues. For specific issues, like ABS problems on certain VW models, consult the forums for known issues and recall information before clearing codes. For instance, the MK60EC1 module on some 2009-2010 models has known issues, and clearing codes without understanding the specific DTCs could affect potential warranty claims.
VWVortex: A Valuable Resource
Forums like VWVortex provide a wealth of information from experienced VW and Audi owners and technicians. They are invaluable for troubleshooting persistent VCDS codes and understanding the nuances of specific models and systems. Searching the forums for your specific code and vehicle model is highly recommended.
