Do I need an OBD-II dongle or scanner to use DIAGLO?

No. DIAGLO diagnoses your car purely from your described symptoms and optional photos of warning lights. If you already have OBD-II trouble codes (DTCs) such as P0301, you can paste them in for extra precision, but a dongle or scan tool is not required.

How much does DIAGLO cost?

DIAGLO is pay-per-report, not a subscription, and a free trial is available. Reports are TURBO at €7.99, PRO at €14.99, and MAX at €24.99. Prices are shown in your local currency at checkout.

What is included in a DIAGLO diagnostic report?

Each report includes an executive TL;DR (recommended action, risk, estimated cost, urgency score), ranked probable causes, deep-dive technical analysis, exact OEM part numbers with cross-references, step-by-step repair instructions, cost estimates, and a built-in AI chat for follow-up questions.

What car information does DIAGLO need?

Your vehicle's year, make, and model (or VIN) and a description of the symptom. You can optionally add photos of the dashboard or fault area, a short video (MAX tier), and any OBD-II trouble codes you have.

Protocol

How it works.
In three steps.

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.

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 TecDoc catalogue and official recall databases.

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.
