Excellent stability and widely regarded as the best overall Passthru device for Mercedes.
Designed to work with standard SAE J2534 devices. It allows third-party hardware to act as a bridge between your laptop and the vehicle’s OBD-II port. Supported J2534 Passthru Devices
Running Xentry Passthru within a virtual machine offers several distinct advantages over a native "bare-metal" Windows installation:
Applying the XDOS or Passthru fix to bypass server-side dealership login screens. xentry passthru vmware
Combining is currently the most accessible and robust method for independent technicians to perform dealer-level diagnostics on Mercedes-Benz vehicles using affordable hardware. By isolating the fragile diagnostic environment within a virtual machine, you protect your main operating system, ensure hardware portability, and can quickly recover from software failures using snapshots.
This is the most common point of failure. If the VM does not see your VCI, Xentry will not detect the car.
While it is exceptional for scanning codes, reading parameters, actuation tests, and basic adaptations, it operates over standard J2534 protocols. Avoid using a Passthru setup over a virtual machine to perform critical, high-risk operations like flashing firmware to powertrain modules (ECU/TCU) unless you are using a premium, highly stable interface like a Scanmatik 2 Pro with a stable, dedicated external power supply hooked up to the vehicle's battery. For daily diagnostics, maintenance resets, and deep fault finding, the XENTRY Passthru VMware setup is one of the safest and most efficient tools you can build.

| Metric | Native (bare metal) | VMware Passthru (optimized) | VMware (default USB 2.0) | |--------|---------------------|-----------------------------|---------------------------| | Average CAN frame latency | 0.8 ms | 1.1 ms | 3.4 ms | | Max burst latency (1 sec window) | 2.3 ms | 3.0 ms | 12.7 ms | | J2534 PassThruReadMsgs timeout errors | 0% | 0.02% | 2.3% | | Xentry “Communication timeout” dialogs | None | None (after tuning) | Frequent |
The installation of the software requires strict adherence to "crack" or "fix" procedures because the software checks for licensing authorization remotely.
Modifying Xentry to run in an unsupported environment may violate Mercedes-Benz license agreements. Use this guide for educational and offline diagnostic purposes only. Always verify functionality on a non-critical vehicle first. This is the most common point of failure
Ensure your device is fully passed through to the VM (check the bottom right corner of VMware for the green lit-up USB icon). Open the Windows Registry ( regedit ) and check HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PassThruSupport.04.04 to ensure your tool is set as the default device. XENTRY Opens But Demands a Login / Password Cause: Missing offline patch or modified daemon files.
Solid State Drive (SSD) is mandatory. XENTRY on a mechanical HDD is unusable. Free space required: 200 GB to 300 GB (depending on how many data packages and add-ons you install). Software & Drivers
