Autokodovi – OBD Dijagnostika

Autokodovi – OBD Dijagnostika is a Serbian-language app that combines vehicle diagnostics, maintenance tracking and used-car inspection tools for mechanics, car owners and buyers. Autokodovi – OBD Dijagnostika puts a searchable fault-code library and OBD-II monitoring in one place and also includes service records and a guided inspection workflow to help with everyday maintenance and pre-purchase checks.

Key features

The app includes a searchable database of over 40,000 diagnostic codes with Serbian descriptions, typical symptoms, common causes and suggested checks covering 42 passenger car brands such as BMW, Mercedes-Benz, Audi, Volkswagen, Opel, Ford, Renault, Peugeot and Fiat, plus organized lists for truck makes like DAF, IVECO, Mercedes and Volvo.

OBD II connection and live data

Live monitoring works with an ELM327 Bluetooth/BLE adapter to read and clear ECU fault codes, display real-time engine parameters (RPM, speed, temperatures, pressures, airflow) and present graphs for up to ten metrics. The app requires a compatible scanner to access live vehicle data; it cannot read ECU data without an adapter.

Service records and inspections

The digital service book supports ten service types (oil, tires, brakes, battery, air conditioning and more), records expenses and mileage, stores vehicle photos and exports service history to PDF. The built-in inspection assistant guides a 51-point used-car check across six categories, offers manual or AI-advisor modes, captures photo evidence, looks up spare-parts prices and generates a full PDF report. The app also includes an in-app blog with news and tips in Serbian.

Advantages include a localized Serbian code database and consolidated tools that reduce the need for multiple utilities while making it easier to share exportable PDF reports and keep maintenance reminders and registration expiry alerts. Autokodovi – OBD Dijagnostika aims to be a practical tool for diagnosis, record keeping and pre-purchase evaluation.

Limitations: the entire interface and content are available only in Serbian, live OBD functions require a compatible ELM327 Bluetooth/BLE adapter, and coverage focuses on the listed passenger and truck brands so some manufacturers or proprietary systems may not be included.
