Diagolia · Automotive diagnostic assistance
Diagolia cross-checks fault codes, symptoms, technical documentation and field cases to rank likely causes and guide checks before replacement.
3 free diagnostics The technician makes the final decision
The challenge
Without cross-checking symptoms, measurements and vehicle context, a familiar lead can result in a rushed repair.
On its own, it does not account for the full context.
Symptoms, measurements and previous work can support or challenge the first hypothesis.
A cause remains a hypothesis until the technician validates it.

AdBlue injection, fluid quality, NOx readings and adaptations to checkThe diagnostic in Diagolia
Diagolia connects each cause to the supporting evidence and the checks to perform. Leads remain hypotheses to confirm.
Prioritized from the evidence available in this case.
Priority cause to check
Fault scan A cause to rule out before the catalyst The injector is consistent with the SCR context and the recorded code.
Field case Similar symptoms Comparable cases point to dosing and blockage checks before replacement.
Other causes to confirm
Fault codes, documentation, web research and field cases.
The most consistent hypotheses rise to the top.
Each lead comes with concrete checks.

FAQ
No. It brings case information together, cross-checks sources and ranks possible causes. Checks and the final decision remain with the professional.
No. Causes are ranked by plausibility and must then be confirmed through physical checks before any intervention.
Fault codes, symptoms, measurements, technical documentation, web research, field cases and added photos, depending on the plan and available information.
It is recommended. Diagolia uses the codes, measurements and observations already recorded; it complements the scan tool without replacing it.
Three free credits, equal to three diagnostics, with technical documentation, lighter web research and limited AI conversation. Photos are not included and vehicle information is limited.
Yes. Diagolia is designed for workshops, technicians and diagnosticians, especially for complex faults, ambiguous codes and intermittent cases.
Yes. Credit volume and some features depend on the selected plan.
