Autokodovi – OBD Dijagnostika

Autokodovi – OBD Dijagnostika is a Serbian-language car diagnostics and maintenance app that combines a comprehensive OBD error-code library, live ECU data reading via ELM327 Bluetooth or BLE adapters and a digital service book in one tool for mechanics, private owners and used-car buyers.

Key Features

Autokodovi – OBD Dijagnostika includes a searchable database of over 40,000 diagnostic codes covering 42 passenger vehicle brands and structured truck codes (DAF, IVECO, Mercedes, Volvo) with Serbian descriptions, common causes and suggested checks. The app supports OBD-II Bluetooth scanners based on ELM327 (BLE) to read and clear diagnostic errors, display live engine parameters such as RPM, speed, temperature, pressure and airflow, and plot up to ten parameters on real-time graphs. A digital service book stores multiple types of service entries, expense and mileage records, vehicle photos, PDF export and registration expiration reminders. The Polo Assistant provides a 51-item inspection checklist across six categories with two review modes (manual or AI advisor), photo evidence and exportable PDF reports. The app also contains a built-in blog with maintenance tips and news and the entire interface and code descriptions are in Serbian.

Advantages

Autokodovi – OBD Dijagnostika helps speed up fault identification through an organized code library and live telemetry, and the graphical data view makes it easier to observe engine behavior during testing. The integrated service book and reminders assist in tracking maintenance history and preserving vehicle value, while the Polo Assistant produces clear inspection reports. Compatibility with low-cost ELM327 Bluetooth adapters makes many diagnostic checks accessible without professional equipment.

Disadvantages

Live OBD functions require a compatible ELM327 Bluetooth or BLE adapter, so without one the app is limited to reference materials and manual inspection tools. The application is currently available only in Serbian, which may be a barrier for non-Serbian-speaking users.
