Modern DiagBox requires an internet connection to "telecode" (program) new ECUs. Old versions of PP2000/Lexia operate entirely offline. This is critical for retrofitting features like cruise control, parking sensors, or swapping a BSI (Body Systems Interface) unit.
Based on the consensus from the PP2000 - LEXIA OLD versions thread on MHH Auto, here is a compatibility cheat sheet: PP2000 - LEXIA OLD versions - MHH AUTO - Page 1
| Vehicle Range | Recommended Software | Version | |---|---|---| | 1996-2002 Peugeot (106, 206, 306, 406) | PP2000 Standalone | v21 | | 2000-2005 Citroën (Xantia, Saxo, C5 Mk1) | Lexia | v22 | | 2004-2009 Citroën (C4, C5 Mk2, C8) | Lexia | v24 | | 2004-2010 Peugeot (307, 407, 607, 807) | PP2000 | v23 | | 2010+ PSA Vehicles | DiagBox | v7.83+ | Modern DiagBox requires an internet connection to "telecode"
If your car has a VAN bus (typically Citroën C5 until 2008 and Peugeot 407 until 2008), you must use Lexia v24 or older. Newer DiagBox versions will not see VAN modules. PP2000 - LEXIA OLD versions - MHH AUTO - Page 1
The infamous "activation" process for PSA diagnostic software has become increasingly complex. Older versions—specifically those from 2010 to 2015—have permanent, stable cracks. Versions like Lexia 5.02 or PP2000 22.14 can be installed without mandatory online updates, preventing the software from locking itself after a "trial period."
