(often referred to as the 7.xx/8.xx series) represent the final evolutionary stages of the software's standalone, offline-capable architecture before the transition to newer, heavily cloud-reliant versions like v9.x. Core Technical Overview

Before dissecting the specific version numbers, let’s establish a baseline. DiagBox is the official dealer-level diagnostic software developed by PSA Group (Peugeot Société Anonyme). It replaces the older PP2000 (for Peugeot) and Lexia (for Citroën) systems, unifying the diagnostic process across the entire PSA range. The software allows users to read and clear fault codes, perform actuator tests, program ECUs, code keys, reset service intervals, and perform complex calibrations like injector coding or steering angle sensor resets.
