An “Inspection Due” warning on your Audi dashboard can be frustrating, especially if you perform your own maintenance. This article discusses a common issue encountered when attempting to reset the inspection reminder using VCDS Lite and provides a potential solution. We’ll explore the error messages, analyze VCDS log files, and explain the steps taken to resolve the problem.
Understanding the “Inspection Due” Warning and VCDS Lite
Modern Audis utilize sophisticated onboard diagnostic systems that track service intervals. When an inspection is due, a warning message appears on the dashboard. VCDS Lite, a diagnostic software package, allows users to interact with these systems, enabling tasks like resetting service reminders. However, this process isn’t always straightforward.
Encountering the Error: “This equipment number is invalid”
When attempting an inspection reset using VCDS Lite, a user encountered the error message: “This equipment number is invalid: Equipment number must be 5-6 digits; 00001-999999.” This error suggests an issue with the equipment number stored in the vehicle’s control module. Further attempts to reset resulted in another error: “Specified values could not be saved on channels 11,12.”
This sequence of events suggests a connection between the invalid equipment number and the inability to save the reset values. The user’s log files, generated by VCDS Lite, provide further insights.
Analyzing the VCDS Lite Log File
The log file reveals repeated attempts to reset the service reminder interval (SRI). Key data points from the log include:
- Control Module Part Number: 8W5 920 890 D
- Component: FBenUSA H18 0373
- Operation: Reset FIX&ESI / INSP
- IDE03352-FIX: Time since last time-dependent inspection: Initially 729 d, eventually reset to 0 d
Despite numerous failed attempts and the persistent error messages, the user eventually succeeded in resetting the inspection reminder. This was achieved by repeatedly selecting the “YES” option on the three-option error message that appeared after attempting the SRI reset. After the third attempt, VCDS Lite successfully cycled through the reset procedure, changing the “Time since last time-dependent inspection” value to 0.
Potential Cause and Solution
The root cause of the initial failure likely stems from the invalid equipment number (potentially 00000) present in the system. While the exact reason for this invalid number is unclear (possibly a dealer entry error), repeatedly attempting the reset procedure seems to have forced VCDS Lite to bypass the invalid equipment number check and successfully reset the inspection timer.
While this solution worked in this specific instance, it’s not necessarily recommended. A more reliable approach would involve identifying and correcting the invalid equipment number within the control module. This may require more advanced VCDS functions or professional assistance.
Best Practices for Using VCDS Lite for Audi Inspection Reset
- Ensure Genuine Software: Use a licensed version of VCDS Lite to ensure compatibility and avoid potential issues.
- Consult Documentation: Refer to the official Ross-Tech VCDS documentation for detailed instructions and troubleshooting guidance specific to your Audi model.
- Proceed with Caution: Modifying vehicle settings with diagnostic software can have unintended consequences. Proceed carefully and understand the potential risks.
- Seek Professional Help: If you encounter persistent errors or are unsure about any steps, consult a qualified automotive technician or Ross-Tech support.
Conclusion
Resetting an Audi inspection reminder with VCDS Lite can sometimes be complicated by invalid equipment numbers. While repeated attempts may resolve the issue, a more thorough solution involves correcting the underlying problem. Always prioritize safe and informed practices when using diagnostic software. Understanding the error messages and analyzing the log files can provide valuable clues for troubleshooting and resolving these issues.
