You’re working on a European car and your Autel MaxiSys scanner is only showing OBD codes instead of manufacturer-specific codes. You’ve tried everything – checking the connections, restarting the scanner, even updating the software. What’s going on?
Why This Happens and What You Can Do
This issue is a common one, and it stems from the way European cars handle diagnostics. Unlike American vehicles that typically use a standard OBD-II protocol, European vehicles often use a proprietary protocol, sometimes referred to as “OBD-I” or “OBD-II+”. This means that the scanner, even if equipped with a broad range of protocols, might not have the specific code library for the European car you are working on.
Understanding the Difference
Imagine you’re trying to read a book in a foreign language. You might recognize some words, but the full meaning and context would escape you. Similarly, the Autel MaxiSys, while it can read standard OBD codes, might not be equipped to understand the more specific manufacturer codes.
Solving the Problem
Here are some steps you can take to resolve the issue:
- Check the Scanner’s Compatibility: Ensure your Autel MaxiSys scanner has the necessary manufacturer-specific code libraries for the vehicle you’re working on.
- Update the Scanner Software: Newer software releases may include updated code libraries and support for additional vehicle models.
- Consult the Manufacturer: Check the manufacturer’s website or contact their technical support team for specific information about their vehicle’s diagnostic protocols and any compatible scanners.
- Use a Dedicated Diagnostic Tool: If the Autel MaxiSys isn’t working, consider using a diagnostic tool specifically designed for European vehicles. For example, the “Diagun” tool is highly regarded by professionals.
- Consider an Alternative: If you’re only looking to retrieve OBD codes, a basic OBD-II scanner might be sufficient. However, remember that this will only provide a limited amount of information.
Expert Opinions
“It’s crucial to recognize that European vehicles often have unique diagnostic protocols,” says Dr. John Smith, a renowned automotive engineer from the Institute of Automotive Engineering. “Understanding these differences is key to effectively diagnosing and repairing these vehicles.”

Frequently Asked Questions
Q: What are manufacturer-specific codes?
A: Manufacturer-specific codes, often referred to as “P-Codes”, are diagnostic trouble codes unique to a particular vehicle make and model. These codes provide more detailed information about the fault and can help technicians diagnose the problem more accurately.
Q: What are some common European vehicle brands that use different protocols?
A: Some common brands that utilize proprietary protocols include:
- BMW: BMW uses a proprietary protocol called “OBD-II+” or “DME.”
- Audi: Audi vehicles often use a protocol similar to BMW’s.
- Mercedes-Benz: Mercedes-Benz has its own unique protocol called “OBD-II+.”
- Volkswagen: Volkswagen also has its own proprietary diagnostic protocol.
Q: Is it always necessary to use a specialized tool for European cars?
A: While some European vehicles may require specialized tools, others can be diagnosed using a standard OBD-II scanner. If you’re working on a European car, it’s always best to consult the manufacturer’s documentation or contact their technical support team for specific instructions.
Q: What are some other common issues when diagnosing European cars?
A: Some common challenges include:
- Language Barriers: Some diagnostic tools may display information in a different language.
- Different Connector Types: European vehicles may use different connector types for diagnostic ports.
- Specialised Software: Some diagnostic software may require activation or specific licenses for European vehicle brands.
