i20 Incorrect Vehicle Coding Error
Summary of the thread
A 2018 Hyundai i20 displayed a fault code at 26,288 km, indicating an incorrect vehicle coding error, with messages appearing in the infotainment and speedometer. This issue is often linked to central communication problems, possibly due to recent software changes or module swaps. The suggested solution was to consult a qualified workshop for diagnosis and correction, which successfully resolved the issue.

I have a scanner, but I'm not sure how to interpret the results for coding. How do specific fault codes point to a coding error, and what should I look for?

Fault codes related to configuration errors, module incompatibility, or implausible data often mean coding problems. For example, codes for a missing module, incorrect variant coding, or communication errors are strong indicators. Interpreting these needs advanced software and understanding of the car's electrics. Given the symptoms and complexity, I'd suggest a qualified workshop. Incorrect coding can cause further issues and damage.

I appreciate the clarification. I went to a local workshop, and they confirmed and fixed the incorrect vehicle coding. The total cost was 360€. Thanks for your help.

That's frustrating. Error messages across multiple systems point to a central communication problem, often from coding errors. Did this start after any recent work, like software changes or module swaps? Have you scanned for specific fault codes? Knowing those would help narrow things down. Do you have a scanner?
