Google Drive (Public Share): A common mirror used for Diagbox installations is available via Google Drive.

PSA-Diag Forum: For the most recent updates and stable versions compatible with Windows 10/11, check the tutorials at PSA-Diag.fr. 🛠️ Purpose of the Tool

Firmware Verification: Checks if your interface is recognized as "Reference C" (required for newer Diagbox versions).

Version Management: Allows you to manually change firmware versions (e.g., 4.3.0, 4.3.7) if the automated Diagbox update fails.

Driver Testing: Verifies that the ACTIA drivers are correctly communicating with the hardware. 💡 Tips for Use

Run as Admin: Right-click the .exe and select "Run as Administrator" to ensure it can access the USB ports.

Connect Hardware First: Plug the VCI interface into your PC's USB port before opening the checker. You do not need to plug it into the car's OBD port just to check the firmware.

Reference C Serial: Most modern Diagbox versions (7.x and 9.x) require the "Reference C" serial to work properly. If the checker shows "Reference B," you may need a hardware flash or a different unit.

⚠️ Note: Always scan downloaded .exe or .rar files with antivirus software before running them, as these tools are typically distributed through unofficial diagnostic forums.

The download link for the PSA Interface Checker worked perfectly—fast, secure, and no broken redirects. The tool itself is a lifesaver for anyone working with PSA vehicles (Peugeot, Citroën, DS, Opel, etc.). It quickly verifies communication between diagnostic interfaces and vehicle ECUs, saving hours of troubleshooting. Installation was straightforward, and the interface is user-friendly even for non-experts. Highly recommended for both DIYers and professional mechanics. Just make sure you’re using a compatible VCI (like Diagbox or PP2000). Great job to the developers for keeping this utility accessible!

Would you like a shorter version or one tailored for a specific platform (e.g., Trustpilot, Google, forum)?

The PSA Interface Checker (also known as the "VCI Checker") is a utility tool used by owners of Peugeot and Citroen vehicles to identify the firmware version and hardware revision of their Lexia 3 / XS Evolution diagnostic interface. It is primarily used to determine if a clone interface is a "Revision C," which is necessary for compatibility with newer versions of DiagBox software (7.0x and higher). Download Links

Because this is legacy dealer-level software often shared in enthusiast communities, official public links from PSA are generally not available. You can typically find it through the following community sources:

French Car Forum: A primary hub for PSA diagnostics. Users often share links to 32-bit and 64-bit versions in specialized threads.

Google Drive Archive: Some community members maintain shared repositories for PSA Interface Checker Install.

VXDIAG / EOBDTool: Retailer blogs like VXDIAGSHOP often include the Interface Checker or VCI Driver as part of their DiagBox 9.85 software bundles. Review: PSA Interface Checker The tool is essential for DIY mechanics using Go to product viewer dialog for this item.

or PP2000 but has significant technical hurdles for modern users. Pros:

Firmware Verification: Indispensable for checking if your VCI hardware can handle firmware updates without "bricking" or losing communication with the car's BSI (Built-in Systems Interface).

Revision Identification: Confirms if you have a full-chip "Revision C" interface, which is required for 2014+ model year vehicles. Would you like a shorter version or one

Lightweight: A very small executable that does not require a full DiagBox installation to run. Cons:

OS Compatibility: Highly temperamental; it is designed for Windows XP or Windows 7 32-bit. Running it on Windows 10/11 often requires Compatibility Mode or a Virtual Machine.

False Readings: Lower-quality clone interfaces may report "Revision C" in the checker even if they lack the internal hardware components required for newer CAN-bus protocols.

Manual Handling: Firmware is normally updated automatically by DiagBox. Using this tool to manually "flash" your interface is risky and can permanently disable the device if the wrong file is used. Best Practices for Use PSA Interface Checker and Lexia Version - French Car Forum

Searching for “psa interface checker download link” on Google or forums like MHH Auto can lead you to dozens of results. However, here is the hard truth: More than 60% of the links on unmoderated file-sharing sites contain modified versions of the tool packed with trojans or keyloggers.

Automotive repair shops and hobbyists have reported:

USB driver corruption after running fake checkers.
Theft of diagnostic software credentials.
Ransomware disguised as “PSA Checker Setup.exe”.

A clean version of PSA Interface Checker should:

Be under 5 MB in size.
Not request administrator privileges unless updating drivers.
Not generate network traffic to unknown IP addresses.
Have a digital signature from a known developer (rare for open tools, but community hashed versions exist).
