After Xentry is fully installed and activated, connect your Openport 2.0 to the PC via USB. Windows should automatically install the J2534 drivers, but you may need to install them manually from the Openport installation directory if not.
is a specialized version of Mercedes-Benz’s diagnostic software designed to comply with Euro 5/6 regulations, which require manufacturers to allow independent workshops access to diagnostic data using standardized interfaces.
Xentry is a resource-intensive program. Ensure your laptop meets or exceeds these specifications before installation:
Never run diagnostic scans—and absolutely never attempt variant coding or adaptations—running solely on the car’s battery. If the vehicle's voltage drops below ~12.5V during a procedure, modules will shut down, disrupting data flow. Connect a dedicated, clean automotive battery maintainer/charger (capable of supplying at least 30–50 Amps) to the under-hood terminals while working. 2. Boot Sequencing Xentry Passthru Openport 2.0
One of the biggest fears with cheap multiplexers is bricking an ECU during a flash due to voltage drops. The Openport 2.0 has a dedicated 12V auxiliary power port. Connect it to a battery charger, and you have rock-solid voltage for those tense 10-minute firmware updates.
If you are determined to go the Passthru route, follow this checklist:

Mastering Mercedes-Benz Diagnostics: A Comprehensive Guide to Xentry Passthru with Openport 2.0
It is notably slower at running "Quick Tests" compared to a dedicated C4/C5 multiplexer. Installation & Configuration Setting up the system involves several technical steps: After Xentry is fully installed and activated, connect
The OpenPort 2.0 has , meaning it cannot communicate with modules on older Mercedes-Benz cars that rely on the K-Line protocol.
is a specialized diagnostic software used for troubleshooting, coding, and vehicle health assessment on Mercedes-Benz vehicles. Unlike the standard OpenShell version designed for factory multiplexers, the Passthru version is built for the SAE J2534 standard, allowing it to work with third-party vehicle communication interfaces (VCIs).
Perform a "Quick Test" to scan all modules, read fault codes (capital F for current, lowercase f/i for stored), and clear them. Xentry is a resource-intensive program
Xentry Passthru works seamlessly with newer Mercedes models that use modern OBD2 communication protocols. 4. Setting Up Xentry Passthru and Openport 2.0
If you work on modern Mercedes-Benz vehicles, you know the name . It is the gold standard for dealer-level diagnostics. However, the official hardware (the SDconnect C4 or C5 multiplexer) costs thousands of dollars.
