How reports are generated

Each report is generated by AI using your exact fault code and vehicle details. The AI cross-references the code against UK repair-cost data, DVSA MOT standards, and vehicle-specific diagnostic patterns to produce a report tailored to your car — not a generic description that applies to every vehicle equally.

Reports are reviewed by the AI-Diagnostics-Pro editorial team before publication. Repair cost estimates are based on UK labour rates and parts pricing from AA, RAC and independent garage surveys. All content is for educational purposes and is not a substitute for professional mechanical diagnosis.
