FOXWELL OBD2 scanner NT710

Mercedes-specific full-system diagnostics are the NT710’s main draw: it is designed to read faults across vehicle modules and run active tests, giving you more to work with than a basic code reader. It also lists a broad set of reset functions, including oil, EPB, SRS, ABS, TPMS, battery, DPF, SAS, injector, transmission, throttle, brake and air suspension resets.

That range is most useful if you want to investigate a warning before booking a repair, or handle supported maintenance tasks at home. It is not presented as a universal scanner for every make: the listed fit is Mercedes-Benz, Sprinter, Smart and Maybach vehicles.

Where it shines

The combination of full-system access and bidirectional control is what separates this scanner from a reader that only retrieves engine codes. Active tests can command certain components, with examples including individual cylinders, doors, windows, the sunroof and wipers. In a practical garage check, you could investigate a misfire by disabling a cylinder, then use the results to make a more informed decision before replacing parts. The tool can also clear fault codes after repairs.

It includes more than 10,000 code definitions, which may help make fault information easier to interpret. That does not mean a code alone confirms which part has failed, diagnosis still depends on the vehicle and the issue. If you prioritise checking specific systems and carrying out supported resets, the NT710 offers more functions than a simple code-clearing tool, if you prefer a straightforward reader for basic engine faults, many of its extra controls may go unused.

What to know

The stated vehicle coverage is limited to Mercedes-Benz, Sprinter, Smart and Maybach. Exact compatibility can depend on the vehicle, and the supplied details do not specify model years or list which functions work on each one. Check those details for your vehicle before relying on a particular reset or active test. Without that information, it is sensible to treat the feature list as a set of supported functions, not a guarantee that every function applies to every vehicle.

Battery registration and air-suspension calibration are among the advanced tasks mentioned, with professional guidance recommended for those procedures. Clearing a warning or a temporary code also does not repair an underlying fault. The NT710 is intended to inform diagnosis and maintenance, not replace the judgement needed for safety-critical work. It offers Wi-Fi updates described as free for the lifetime of the tool, with no subscription fee stated.

Best use cases

It suits you if you own one of the listed vehicle makes and want to read beyond basic engine codes, check selected components, or perform resets that match your vehicle. It may also be useful before a service visit: you can arrive with fault information in hand rather than relying only on a dashboard warning. Better to avoid it if you need confirmed coverage for an unlisted make, want a simple plug-in reader, or expect every advertised function to work across all model years.

To wrap up

Choose the NT710 when its Mercedes-focused system access and reset functions match a vehicle you own, and you are comfortable using diagnostic information as a starting point. For occasional engine-code checks, a simpler scanner may be a more practical fit, for advanced calibration or uncertain compatibility, confirm the exact vehicle support and seek qualified help before proceeding.
