Full Capabilities
DiagBox v9.208 is not a generic code reader. It is the actual OEM factory diagnostic platform developed by ACTIA for Stellantis. Here is what it covers.
Reads and clears manufacturer-specific fault codes across every installed ECU — engine, gearbox, ABS/ESP, airbag, BSI, climate, parking, infotainment, EPS, and more. Full PSA fault descriptions with status context, not just generic P-codes.
Stream up to 9 real-time parameters simultaneously in list or graph view. Coolant temp, boost pressure, lambda values, injection timing, fuel rail pressure, MAF, EGT, and hundreds more. Log to file for offline analysis of intermittent faults.
Activate components on command: injectors, EGR valve, turbo actuator, throttle body, fuel pump, cooling fans, door locks, windows, lighting, ABS valves, HVAC blower. Full bi-directional control — not just passive monitoring.
Access 300+ configurable BSI parameters. Activate/deactivate cruise control, DRL, speed locking, parking sensors, TPMS, blind-spot detection, comfort lighting, tow bar module, and dozens more. Fully offline for pre-2016 vehicles.
Program new transponder keys, register replacement keys, and perform immobilizer alignment procedures. Full key-to-BSI pairing for supported vehicle generations.
Flash updated firmware to engine ECU, automatic gearbox, ABS, airbag, and BSI modules using official Stellantis calibration files. Bring ECUs to the latest software revision.
Force particulate filter regeneration cycles directly from the software. Reset Eolys additive counters after refill. Clear soot accumulation faults and restore DPF system health.
Program IMA correction codes after injector replacement. Essential for maintaining proper fuel metering, emissions compliance, and smooth engine operation on common-rail diesel systems.
Battery registration (BMS reset), AdBlue/SCR counter reset, service interval reset, ABS electronic brake bleeding, steering angle calibration, throttle body adaptation, and guided diagnostic procedures with wiring diagrams.

Why DiagBox
No aftermarket tool matches DiagBox's depth on PSA vehicles — because DiagBox is the factory tool, not an approximation of one.

FAQ
Common questions from technicians and workshop owners.
Yes. This version is pre-configured to operate without needing Stellantis server authentication. All core offline functions — fault codes, live data, actuator tests, service resets, and telecoding for pre-2016 vehicles — work immediately after installation.
A Lexia 3 (PSA XS Evolution) interface is the primary supported hardware. Full-chip clones with 12 NEC relays and 7 optocouplers provide reliable performance for all diagnostic functions. The VXDIAG VCX SE is a modern WiFi alternative for 2006+ CAN-bus vehicles.
Yes. DiagBox v9.208 is compatible with Windows 7, 8, 10, and 11 — all 64-bit. It also runs inside VMware or VirtualBox virtual machines for macOS or Linux users.
Telecoding on vehicles manufactured after approximately 2015–2016 requires online authentication through the Stellantis Service Box portal. This is a server-side restriction built into the vehicle ECUs, not a software limitation. Pre-2016 telecoding works fully offline.
Yes. Multiple technicians confirm that v9.208 connects successfully to hybrid models. Coverage includes plug-in hybrid variants of the 3008, 508, C5 Aircross, DS 7, and others.
Yes — remote installation via TeamViewer or AnyDesk is available. We guide you through the complete setup process to ensure DiagBox is running correctly on your system.
Yes. DiagBox is developed by ACTIA for PSA Group (now Stellantis). It is the identical diagnostic platform used in every authorized Peugeot, Citroën, DS, and select Opel dealerships worldwide. No aftermarket tool replicates its full capability on PSA vehicles.
