Best Scan Tool for Mercedes-Benz
Whether you own a Mercedes-Benz C-Class, E-Class, GLE, or S-Class, a good scan tool can save you thousands in dealership fees by helping you read and clear codes, reset warning lights, and even perform advanced coding. But Mercedes vehicles are complex, and not every scanner supports their unique modules, protocols, and features.
So, what’s the best scan tool for Mercedes-Benz in 2024?
This guide covers the top diagnostic tools for both DIYers and pros, including models that work with OBD2, CAN, and proprietary Mercedes systems like XENTRY and DAS.
What to Look for in a Scan Tool for Mercedes-Benz
✅ OEM-Level Support
Mercedes uses manufacturer-specific systems (ABS, SRS, transmission, air suspension, AdBlue, etc.). A good tool must go beyond generic OBD2 codes.
✅ SRS, ABS, and Transmission Diagnostics
Standard OBD2 tools can’t access modules like airbags, brakes, or automatic transmissions—you need full system coverage.
✅ Service Resets & Adaptations
Look for tools that can reset oil service lights, electronic parking brake (EPB), DPF regeneration, battery registration, and more.
✅ Bi-Directional Controls (Advanced Users)
This lets you command systems (e.g., open/close valves, activate fans)—a must-have for diagnostics or part testing.
✅ Live Data & Graphing
Real-time data helps you track sensor performance, misfires, temperature, and fuel trims.
