Code Reader Scan Tool Diagbox V9.91 PP2000 Lexia3 PSA Diagnostic

This is a full diagnostic suite for PSA vehicles — the kind of kit that lets you pull codes, clear faults, and understand what's actually going on under the bonnet without paying a dealer's rates. It combines Diagbox software with PP2000 and Lexia3 functionality, covering everything from straightforward fault reading to deeper system interrogation across Citroën and Peugeot models.

The hardware reference is 921815C with full chip architecture. Software comes in both V7.83 and V9.91 versions, with multi-language support across English, French, German, Spanish, Italian, Polish, Portuguese, Czech, Hungarian, Russian, Swedish, Turkish, and Japanese. Updates are included. OBD2 connectivity means it works with standard diagnostic protocols.

Important: PP2000 and Lexia3 require Windows XP; Diagbox runs on Windows 7 and later. Don't install multiple packages on the same machine — Diagbox already includes PP2000 and Lexia3 functionality. Close your antivirus and network connection before installation to avoid false triggers and errors. This isn't a plug-and-play consumer gadget; it's a proper technician's tool that needs careful setup, but once it's running, it does the job thoroughly.
