Colour OBD2 Gauge, Trip Computer and Engine Monitor
The ScanGauge 3 is a compact OBD2 digital gauge and trip computer that gives you real-time vehicle information while you drive. It plugs into the vehicle’s OBD2 port and displays live data such as coolant temperature, intake air temperature, RPM, fuel economy, voltage, and more on a clear colour screen.
It is not just a basic code reader. The ScanGauge 3 is best thought of as a live vehicle monitor, economy tool, and trip computer with basic engine fault code reading built in.
Best Suited For
The ScanGauge 3 is best suited to drivers who want to monitor their vehicle while driving, improve fuel economy, keep an eye on temperatures, or add extra gauges without installing permanent sensors. It is popular with 4WD owners, towing users, diesel drivers, motorhome owners, fleet users, and anyone who wants live vehicle data on display.
It is also a good choice for older vehicles with limited factory gauges, or modern vehicles where important information is hidden inside the ECU rather than shown on the dashboard.

System Diagnostics
The ScanGauge 3 can read and clear standard OBD2 engine fault codes and display live engine data from the vehicle’s ECU. It is useful for checking a check engine light and monitoring data that helps show how the vehicle is running.
It is not a full-system diagnostic scan tool. It does not provide full ABS, SRS airbag, transmission, body control, coding, programming, or advanced service function coverage.
Service Functions
The ScanGauge 3 is not designed for service reset work. It does not perform oil reset, EPB reset, DPF regeneration, injector coding, battery registration, ABS bleeding, or similar maintenance functions.
Its strength is real-time vehicle monitoring, trip data, fuel economy tracking, and basic engine code reading.
Vehicle Compatibility
The ScanGauge 3 works with most OBD2-compliant vehicles fitted with a standard 16-pin OBD2 port. Compatibility can vary depending on vehicle make, model, year, fuel type, and the data made available by the vehicle’s ECU.
Some vehicles support a wider range of live data than others. Gauge availability depends on what your vehicle reports through OBD2.

Is This the Right Scan Tool for You?
The ScanGauge 3 is the right choice if you want a high-quality live vehicle monitor, trip computer, and digital gauge display with basic engine code reading. It is excellent for drivers who care about temperatures, fuel use, towing, engine load, and real-time data while driving.
If you mainly want to diagnose faults across ABS, airbags, transmission, or perform service resets, choose a dedicated diagnostic scan tool instead. The ScanGauge 3 is a monitoring tool first and a basic engine code reader second.
