The Autel MS906TS is a high-level bidirectional diagnostic scan tool capable of performing most automotive diagnostic functions, excluding module coding. While coding functionality requires a subscription to manufacturer data, the MS906TS excels in diagnostics and live data analysis. This review details its capabilities and performance based on firsthand experience with European vehicles.
The Autel MS906TS, purchased approximately four years ago for around $1300, has proven invaluable for diagnosing and resolving issues on various European makes, including BMW, Mercedes, and Range Rover. Its bidirectional communication capabilities enable active testing of components, crucial for pinpointing faults.
For Mercedes vehicles, the MS906TS has been extensively used to address complex systems like air suspension, NOx sensors, and DEF heaters. Live data graphing helped analyze sensor readings and system behavior, leading to accurate diagnoses. On BMWs, it efficiently reset maintenance lights and facilitated brake system work. With the Range Rover, the tool proved essential in diagnosing DPF problems, performing throttle body relearns, and activating solenoids to isolate emissions-related issues.
The tool’s live data and graphing functions consistently provide critical insights into system performance, enabling efficient troubleshooting. Visualizing data in real-time significantly aids in understanding complex interactions and identifying anomalies.
While the MS906TS performs exceptionally well, there are a couple of drawbacks. Firstly, the cost of updates is substantial, roughly half to two-thirds the initial tool price. While updates haven’t been necessary due to the absence of newer model vehicles, this expense is a considerable factor. Secondly, the lack of comprehensive instructions can be frustrating. Navigating the software and understanding manufacturer-specific implementations requires significant trial and error. However, this limitation is attributed to the complexities of vehicle manufacturers’ data systems rather than the tool itself.
Despite these minor shortcomings, the Autel MS906TS remains a reliable and powerful bidirectional scan tool. Its durable construction, excellent battery life, and consistently fast performance demonstrate its quality. The MS906TS offers significant value for experienced DIYers and professionals working on European vehicles, proving itself as a robust and effective diagnostic solution.
