When it comes to diagnosing Mercedes-Benz vehicles with Xentry software, two popular J2534 passthru devices often come up for comparison: the VXDIAG VCX SE for Benz and the Scanmatik 2 Pro (SM2 Pro). Both devices support passthru functionality, but they serve different needs and scenarios. Here’s a breakdown of each device’s strengths and weaknesses in the context of Xentry Passthru.
Scanmatik 2 Pro (SM2 Pro) – Great for Small to Medium Repair Shops
The Scanmatik 2 Pro is a solid choice for small to medium repair shops where Mercedes-Benz is a frequent but not primary brand. This device allows you to use key Mercedes-Benz diagnostic tools such as DAS, Xentry, Vediamo, and Monaco with great functionality. It can handle most models from Mercedes, especially newer cars, but with a few limitations:
- Older Models (Pre-2005): Scanmatik 2 Pro may struggle with older vehicles. Some control units may not be detected, and certain older vehicles may fail to connect with Xentry.
- Trucks: Vehicles that require DAS for trucks are generally not supported by Scanmatik 2 Pro.
- Newer Models: On the other hand, the Scanmatik 2 Pro can work well with newer models, including Xentry Cars 2024.09 and Xentry Trucks 23.12, as well as more recent versions of Xentry, when used in passthru mode.
VXDIAG VCX SE – A More Universal and Reliable Solution
The VXDIAG VCX SE stands out as the more versatile and powerful device, especially for those looking to work with the latest versions of Xentry. It supports DoIP (Diagnostics over Internet Protocol), making it future-proof and highly compatible with the latest Xentry versions. The VXDIAG VCX SE has several advantages:
- DoIP Support: This device works seamlessly with modern cars, including those with advanced DoIP diagnostics, which are increasingly common in new Mercedes-Benz models.
- Xentry XDOS Compatibility: The VXDIAG VCX SE works flawlessly with both Xentry Openshell and Xentry Passthru versions. When tested with Xentry 2023.12 XDOS, it provided full functionality for diagnostic tasks, including with newer models like the Mercedes-Benz W167 (2021).
- Performance: In a real-world test, the VXDIAG VCX SE performed better than the Scanmatik 2 Pro when diagnosing the Mercedes-Benz W167 2021, where the Scanmatik 2 Pro failed to connect, while the VXDIAG VCX SE worked without issues.
Key Differences and Which One to Choose
- Compatibility with Newer Software: The VXDIAG VCX SE is better suited for users who require compatibility with the latest software versions like Xentry 2023.12 and beyond. It also offers better performance in passthru mode for recent vehicles.
- Older Vehicles and Budget: If your shop primarily deals with older models (pre-2005), or if Mercedes-Benz is not the core brand in your business, the Scanmatik 2 Pro could be sufficient for your needs, offering a more budget-friendly solution for basic diagnostic tasks.
- Versatility and Future-Proofing: If you plan to work with a broad range of Mercedes models, including the latest vehicles, the VXDIAG VCX SE is a more reliable and future-proof option. It offers better support for newer diagnostic protocols like DoIP and is more stable when working with both Xentry Openshell and Xentry Passthru.
Conclusion
Both the Scanmatik 2 Pro and VXDIAG VCX SE are capable J2534 passthru devices, but the VXDIAG VCX SE stands out for its superior compatibility with newer software and models. While the Scanmatik 2 Pro may be more suited to smaller shops or those dealing with older vehicles, the VXDIAG VCX SE is the better choice for those who need reliable diagnostics across a wide range of Mercedes-Benz vehicles, especially newer models and future software updates.
