Before attempting to download or install the 7.58 update, your environment must be correctly configured. Diagbox is notoriously sensitive to operating system changes.

Diagbox is the official professional diagnostic software suite for the PSA Group—now part of Stellantis—which manufactures Peugeot, Citroën, and DS Automobiles. Its predecessor tools were known as PP2000 (for Peugeot) and Lexia (for Citroën), but Diagbox consolidated them into one powerful, all-encompassing platform.

Official diagnostic software is often distributed through manufacturer portals like the Peugeot Citroen ServiceBox , which provides tools for professional technicians. However, many DIY users rely on community-shared incremental updates.
Disconnect your laptop from Wi-Fi or Ethernet before running the update setup file.
DiagBox was designed as a comprehensive interface that integrates multiple legacy diagnostic tools into a single platform. Version 7 was a milestone in this transition. The move from version 7.57 to 7.58 represents a specific incremental update intended to fix bugs, expand the database of vehicle parts, and improve communication protocols with the vehicle’s Electronic Control Units (ECUs). In a professional environment, these updates are delivered through an official subscription service that ensures the integrity of the software and the safety of the vehicle's onboard computers.
