Free Download Diagbox 9.129, 9.143, 9.150, 9.186 and up.

Diagbox is diagnostic software for Peugeot and Citroën vehicles, used in conjunction with the Lexia/PP2000 interface. Versions 9.129, 9.143, 9.150, 9.186, and higher provide a full set of tools for reading and clearing DTCs, coding control units, performing actuator tests, and updating the configuration of electronic modules.

• Support for Peugeot / Citroën / DS models, and in some cases, multi-brand models within the PSA group.
• Diagnostics of electronic control units (ECU), ABS, Airbag, BSI, and more.
• Ability to reset counters, adaptations, and perform service operations (e.g., Eolys reset / regeneration / additive refilling).
• Support for installation on Windows 7 / 8 / 10 and operation in multiple languages.
• The version is often distributed in a "pre-activated" form—with a pre-installed activation or patch to bypass licensing restrictions.

• Version 9.143 is used for diagnostics and repairs of Peugeot, Citroën, and PSA Group vehicles.
• Extended model support – covers all recent Peugeot, Citroën, and Opel/Vauxhall models (within the PSA ecosystem).
• Multilingual support – the software is available in multiple languages: English, German, French, Polish, Russian, and others.
• System requirements: Windows 10 (64-bit), Intel (i3/i5/i7) or Ryzen CPU, RAM ≥ 4 GB, hard drive ≥ 80 GB (SSD recommended).
• Offline option coding (telecoding) – for vehicles up to ~2015. After 2015, this capability is still limited and is only implemented in certain cases (DPF, AdBlue, keys, VIN, etc.).
• Supported functions: reading/clearing errors, scanning, displaying live data, actuator tests - similar to the basic diagnostic functions from 9.129.
