4. VAG Guided Functions & Refresh Hidden Settings: Provides step-by-step guided diagnostics for VW, Audi, Skoda, and Seat vehicles. The Refresh Hidden feature allows users to toggle built-in software functions on or off based on personal preference.
5. Bidirectional Control / Active Tests: Enables real-time activation and testing of specific vehicle subsystems or components to verify operational integrity.
6. 36+ Specialized Service Functions: Includes Oil Reset, EPB, TPMS, BMS, Brake Bleed, DPF, Immo Keys, Injector Coding, SAS, Suspension Calibration, Throttle Matching, Window/Door/Roof control, Seat adjustments, Air/Fuel ratio adaptation, Language Change, Headlamp alignment, Tire Size input, TEC Learn, Cylinder balancing, Transmission Adaptation—and more, with ongoing additions.
7. OE-Level Full System Diagnostics: Accesses all available vehicle modules—including Engine, ABS, SRS, Transmission, EPB, Chassis, Steering, Emission, Fuel, and TPMS—to read/clear DTCs, view live data (in text or graph format), retrieve freeze frame data, run active tests, and execute special functions for precise diagnosis.
8. Extensive Coverage for 10,000+ Vehicles: Supports KWP, CAN, UDS, OBDII, D-PDU, J2534, and RP1210 protocols. Fully compatible with 2018+ FCA vehicles featuring Security Gateway (AutoAuth). Covers the vast majority of U.S., Asian, and European makes and models.

Newly Added Functions in 2023

• Full Diagnostics for McLaren & Tesla: Capable of complete system-level diagnosis on McLaren and Tesla new-energy vehicles—a capability unmatched by most competing scanners.
• FCA Vehicle Access via AutoAuth: For FCA vehicles equipped with a Security Gateway module, the MS908S Pro II enables login via an FCA account to perform DTC clearing, bidirectional tests, and calibrations across Fiat, Chrysler, and Alfa Romeo models.
• Battery Testing (with BT506): When paired with the optional BT506 battery tester, it can scan the BMS module, identify battery type, assess aging and storage condition, and provide tailored maintenance recommendations. (Note: BT506 sold separately.)
• Compatibility with MV105/MV108 Inspection Cameras: Bundled with the Autel MV108 digital inspection camera, transforming the scanner into a video borescope for inspecting hard-to-reach areas.
• Pre- and Post-Scan Reporting: Generates detailed reports before and after service to inform customers and support insurance claim documentation.
• VIN & License Plate Scanning: Quickly retrieves vehicle details—including manufacturer, model year, body type, engine code, and assembly location—by scanning the VIN or license plate, eliminating manual entry.
• Wi-Fi Printing: Enables wireless printing of diagnostic reports directly from the device using a Wi-Fi-enabled printer.
• Support for D-PDU/RP1210 Protocols: Integrates the latest communication standards to ensure compatibility with newer vehicle models.
