Is your MINI’s check engine light illuminated? This indicates a problem that your car’s On-Board Diagnostics (OBD) system has detected and flagged with a specific code. Understanding these Mini Obdii Codes can provide valuable insight into the issue before you even visit a mechanic. This guide will provide a comprehensive list of common OBDII codes for MINI vehicles. Use an OBD-II scanner to retrieve the code and then reference the table below for potential problems.
Common Mini OBDII Codes and Their Meanings

Decoding Unlisted or MINI-Specific Codes
If you encounter a code not listed here, especially one starting with “P1” (MINI-specific), it’s recommended to consult a qualified MINI technician. These codes require specialized diagnostic equipment and expertise for accurate interpretation.
Conclusion: Mini OBDII Codes and Your Next Steps
While this list provides a helpful starting point for understanding mini obdii codes, remember that a proper diagnosis requires a comprehensive assessment by a trained professional. If your check engine light persists or you’re unsure about the next steps, schedule an appointment with a certified MINI service center. They have the tools and knowledge to accurately diagnose and repair your vehicle.
