10 Best foxwell obd 2 scanners 2025 in the United States

The FOXWELL HD500 is a specialized OBD2 scanner designed primarily for heavy-duty diesel trucks from brands like Cummins, Caterpillar, Detroit, and more. Its standout feature is advanced DPF (Diesel Particulate Filter) service functions, including regeneration and status monitoring, which helps maintain engine health and fuel efficiency. The scanner also offers a professional cylinder cut-off test, useful for identifying cylinder or injector problems—ideal for mechanics or experienced users working on diesel engines.

It supports multiple key diagnostic areas such as Engine, ABS, SRS, and more, covering a wide range of trucks, buses, and construction vehicles with various diagnostic protocols. Connectivity is straightforward with included adapters, and the device runs on Android 9.0, providing a familiar interface and ease of use. The lifetime free software updates ensure it stays current with new vehicle models, while 24/7 tech support offers assistance when needed.

Some advanced functions like Allison transmission diagnostics and VGT calibration are not supported, and speed limit reset is only available on select models, so it is important to check vehicle compatibility before buying. The HD500 is slightly heavier than some handheld scanners, which might affect portability, but its robust functionality makes it a practical choice for professional use and serious DIYers who want a reliable, all-in-one diagnostic tool for heavy-duty trucks.

The FOXWELL NT301 OBD2 Scanner serves as a solid tool for both home and professional mechanics. It offers a comprehensive range of diagnostic functions like reading DTCs (Diagnostic Trouble Codes), checking I/M readiness status, and accessing live sensor data. This makes it particularly useful for diagnosing and fixing Check Engine Light issues. The compatibility is extensive, covering most worldwide cars, SUVs, light trucks, and 12V diesels, although it has limitations with some specific brands like Fiat, Alfa Romeo, and certain French and Korean models. Always check vehicle compatibility before purchasing to avoid issues.

The user interface is user-friendly, featuring a 2.8-inch color screen and straightforward hotkeys for essential functions, which can be very convenient for quick diagnostics. However, the device is not compatible with Mac or iOS systems, limiting its versatility if you use those platforms. Connectivity is straightforward via the 16-pin DLC in your vehicle, and it does not require a battery, which is a plus. For software updates, it supports Windows XP/7/8/10, but again, no Mac or iOS support.

The live data streaming and data logging capabilities are robust, allowing for real-time monitoring and troubleshooting of engine problems. It is noteworthy that the device only reads engine system codes and doesn't support ABS or SRS, which could be a drawback for those looking for more comprehensive vehicle diagnostics. The NT301 also comes with a 1-year warranty. However, if you need a broader range of diagnostics beyond the engine system, you might need to look for other options.

The FOXWELL NT710 Scan Tool is a solid choice if you own a BMW, Mini, or Rolls-Royce and want a reliable diagnostic device that gives you dealership-level capabilities at home. It covers full-system diagnostics, meaning it can read and clear fault codes from engine, transmission, airbags, ABS, and many other systems. The tool also supports all common service resets, such as battery registration and oil light resets, which helps maintain your vehicle properly without visiting a mechanic.

Its Android 9.0 operating system and 5.5-inch touchscreen make the interface smooth and easy to navigate, even if you’re not tech-savvy. The scanner has strong connectivity features, including lifetime free Wi-Fi updates, so you can keep it current without extra costs. It automatically recognizes your vehicle via Auto-VIN, simplifying setup and report generation. A standout feature is bi-directional control, allowing you to activate components like pumps or solenoids directly from the device—this can save significant troubleshooting time. ECU coding is supported but limited mostly to activating or hiding existing features on certain BMW models, not full programming.

Some advanced functions like ECU coding require additional hardware (a Doip connector) and have restrictions based on vehicle model and year. Battery parameter modifications are only available for older BMW series, which may limit usefulness if you have a newer model. While it covers many diagnostic areas, the tool is specialized for BMW/Mini/Rolls-Royce, so it won’t be suitable if you have other car brands. This makes the FOXWELL NT710 a comprehensive, user-friendly diagnostic and maintenance tool for BMW and related vehicles, providing robust features usually found only in professional-grade equipment and offering owners greater control over their car’s health.
