One quality standard — zero compromise
Protocol

How it works.
In three steps.

01
step 01

Describe the symptom

Noise, warning light, OBD code, odd behaviour. You add the make, model, engine and mileage. You can attach a photo of the dashboard.

02
step 02

The AI diagnoses

Diaglo works out the failure mechanism for your exact car, ranks the likely causes, and checks part numbers against the Diaglo Parts catalogue and official recall databases.

03
step 03

You get the engineer report

A repair plan with OEM codes, labour estimate, and what to ask at the shop. You hand it over and stay in control of the conversation.

Deliverable

What's in the report.

The same document a workshop manager would write after a full inspection, built specifically for your car.
