Xentry Passthru Openport 2.0 (480p — 2K)

The Openport 2.0 uses a standard 16-pin OBD-II male connector. However, newer Mercedes (W204, W212, W166 etc.) require pin 1 (Switched Ignition). Some cheap OBD extension cables omit this. Ensure your cable supports full pinout or use a Y-cable to supply external 12V if the car’s OBD port provides low voltage.

Xentry Passthru paired with a Tactrix Openport 2.0 is a popular, cost-effective setup for Mercedes-Benz diagnostics and coding. It allows enthusiasts and independent shops to access dealer-level software without the high cost of a dedicated SD Connect C4 or C6 multiplexer. How the Setup Works Xentry Passthru:

This version of the Mercedes diagnostic software is specifically designed to work with J2534-compliant hardware (like the Openport 2.0). Openport 2.0:

Originally designed for tuning Subarus and Mitsubishis, this device acts as the bridge between your laptop's USB port and the vehicle’s OBD2 port. Compatibility: This setup generally works best on vehicles from 2006 onwards

(CAN-bus models). It typically does not support older K-Line vehicles or specialized functions like DoIP (required for flashing new head units or digital instrument clusters). Core Capabilities Fault Diagnosis:

Read and clear fault codes (DTCs) across all modules (Engine, Transmission, ABS, Airbags, etc.). Live Data:

View real-time sensor data to troubleshoot intermittent issues. Actuations:

Test specific components like cooling fans, fuel pumps, or electronic parking brakes.

Perform "Variant Coding" to enable or disable hidden features (e.g., seatbelt chimes or Agility mode). Key Considerations Driver Setup:

The Openport 2.0 requires specific J2534 drivers to be recognized by Xentry. Voltage Reliability:

While great for diagnostics, the Openport 2.0 can sometimes be unstable during long ECU flashing sessions. Always use a battery maintainer to keep voltage steady. Software Versions:
