The ePER acronym stands for (commonly referred to simply as the Electronic Parts Catalog). It is a database containing exploded technical diagrams, part numbers, modifications, and supersessions for vehicles manufactured by the Fiat Group.

The openPER project is a remarkable feat of reverse engineering. A dedicated community developer analyzed the Microsoft Access database and ZIP file archives from the original ePER DVD. They then rebuilt it as a modern, open-source web application using C# .NET Core and a MariaDB database. The result is a robust, searchable platform that ensures this priceless technical data will never be lost to time. The version currently used on the Fiat Forum ( eper.fiatforum.com ) is powered by openPER and uses database v84.

: Enter your 17-character Vehicle Identification Number to see the exact build of your car, including options and production date .

: Official documentation often specifies that older versions (such as the DVE version) were optimized for Microsoft Internet Explorer .

Official full access typically requires a paid subscription through Technical Information Fiat , which may be costly for casual home mechanics.

The Fiat Eper Catalog boasts an impressive array of features that make it an indispensable resource for anyone working with Fiat vehicles. Some of the key features include:

If you do not have a VIN, manually select the Brand →right arrow →right arrow →right arrow Engine type.

Do you prefer to use or are you looking to set up an offline version ?

The factory designation for that specific car configuration.

Example: If you need a front brake pad, you would look for the "Brakes" group (often Group 33 or similar).

Users can access the database through a few different channels depending on their needs.

While the catalog is robust, some older public ePER mirrors may not have the absolute latest 2026 updates for the newest Stellantis models.

While ePER is a powerful tool, it does have some limitations, particularly with the public-facing version.

Introduction to Fiat ePER The automotive industry relies heavily on precise component mapping to ensure that vehicles are serviced, repaired, and maintained with accuracy. For vehicles manufactured under the Fiat Chrysler Automobiles (FCA) umbrella—now a core part of Stellantis—the definitive tool for this task is the Fiat ePER (electronic Parts ExchanGe / electronic Parts Catalogue). It serves as the primary web application and database used by dealer networks, independent mechanics, and automotive enthusiasts to consult technical parts catalogues, cross-reference part numbers, and analyze vehicle assemblies.
