The Autel MS906TS, a high-level OBD2 bi-directional scan tool, offers extensive diagnostic capabilities for DIY enthusiasts and professionals alike. This comprehensive review explores its functionalities, strengths, and weaknesses based on firsthand experience with European vehicles.
Functionality and Real-World Applications
The Autel MS906TS excels in performing a wide array of diagnostic tasks, falling just short of module coding which often requires manufacturer-specific subscriptions. In my experience with BMW, Mercedes, and Range Rover vehicles, it has consistently delivered reliable performance.
For Mercedes, the MS906TS proved invaluable in diagnosing and addressing issues related to air suspension, NOx sensors, DEF heaters, and other common problems. Its live data and graphing functions were instrumental in pinpointing the root causes of these faults.
On BMWs, the tool efficiently handled tasks such as resetting maintenance lights and assisting with brake-related work. Similarly, for the Range Rover, it facilitated the diagnosis of DPF issues, throttle body recalibrations, and solenoid activations to troubleshoot emissions codes.
The tool’s bi-directional control capabilities allowed for activating various components, providing a deeper understanding of system functionality and facilitating accurate diagnoses. This feature, coupled with live data monitoring, significantly streamlined the troubleshooting process across all tested vehicle makes.
Cost, Updates, and User Experience
While the initial investment for the Autel MS906TS was considerable (around $1300 four years ago), the tool’s capabilities have justified the expense. Used options might offer a more budget-friendly entry point. However, a significant drawback is the high cost of software updates, which can run up to two-thirds of the tool’s original price. These updates were initially included for two years, but subsequent updates require a separate purchase. While not necessary for older vehicles, newer models may require the latest software for comprehensive diagnostics.
A notable frustration is the lack of comprehensive instructions. Navigating the tool’s interface and understanding manufacturer-specific implementations often requires trial and error. This complexity stems from variations in how each manufacturer integrates with the tool, rather than a deficiency in the Autel device itself.
Durability and Performance
Despite the learning curve and update costs, the Autel MS906TS has proven to be a durable and reliable tool. Battery life remains excellent, and the device operates with consistent speed and responsiveness even after four years of use. Its robust construction has withstood regular use in a demanding environment.
Conclusion
The Autel MS906TS stands out as a powerful OBD2 bi-directional scan tool capable of handling complex diagnostic tasks on a variety of European vehicles. While the cost of updates and lack of user-friendly instructions are drawbacks, its overall performance, durability, and comprehensive functionalities make it a valuable investment for serious DIYers and professionals seeking advanced diagnostic capabilities. The ability to perform bi-directional controls, coupled with live data and graphing, sets this tool apart, providing in-depth insights into vehicle systems and facilitating accurate troubleshooting. If module coding is not a primary requirement, the MS906TS offers a robust and reliable solution for advanced automotive diagnostics.
