Real-Time Vehicle Monitoring, Trip Data & Engine Diagnostics in One Compact Unit
The ScanGauge 3 is an ultra-compact OBD2 vehicle monitor designed to give drivers constant access to live engine data, fuel economy information, trip computer functions, and basic diagnostic capability from inside the cabin. It is built for everyday drivers, fleet users, towing setups, and enthusiasts who want more visibility over how a vehicle is performing without stepping up to a full scan tool.
Your vehicle must be OBD2 compliant to work with this tool.
Mounted in the cabin and powered directly through the diagnostic port, the ScanGauge 3 provides a practical way to monitor key vehicle data in real time. With its capacitive touch display, customisable screen layouts, multiple trip computers, audible and visual alarms, and built-in code reading, it is designed to be useful every time you drive, not just when a fault appears.

Digital Gauges & Monitoring
The ScanGauge 3 is designed to show what is happening under the bonnet in real time. You can monitor live parameters such as RPM, coolant temperature, voltage, fuel economy, and other supported OBDII data, with the ability to customise both the number of gauges shown and the layout across multiple screens. It also supports ScanGauge’s X-Gauge system, which allows vehicle-specific gauges such as transmission temperature, oil temperature, and other extended parameters where supported.
Fuel Economy & Trip Computers
One of the biggest strengths of the ScanGauge 3 is the amount of trip and fuel data it keeps available while you drive. It includes three time and distance trip computers covering Current Trip, Today Trip, and Previous Day Trip, plus a dedicated tank trip computer that starts when you tell the unit the tank has been filled. Data tracked includes fuel economy, fuel used, coolant temperature, distance driven, hours driven, average speed, fuel cost, tank-to-empty, and distance until empty. The stored data is retained even when power is disconnected.
The official ScanGauge page also highlights the value of real-time fuel economy feedback, noting that better driving habits can improve fuel economy significantly. It specifically lists instant and average fuel economy, fuel used, cost of fuel used for each trip, cost per mile, and fuel use per hour as available data points.
Engine Diagnostics
The ScanGauge 3 also works as a basic OBD2 scan tool. It can read and clear diagnostic trouble codes, display code meanings, show pending codes, and report emissions readiness status so you can see whether onboard tests have been completed before inspection. It can also show conditions present when a fault was detected, helping with basic troubleshooting.
Installation & Design
The ScanGauge 3 is built for quick installation and everyday use. It plugs directly into the OBD2 port under the dash, requires no batteries, and automatically determines the vehicle protocol when connected. It includes a 6-foot cable and mounting hardware so it can be positioned conveniently inside the cabin and quickly removed for use in another vehicle if needed.
User Experience
The capacitive touch display is designed to be simple and easy to use, with swipe controls for adjusting brightness. The display can be colour-matched to the interior for a more integrated look, and the unit supports both metric and imperial measurements including kilometres, litres, Celsius, and kPa. It also stores your preferences so the setup remains consistent once configured.
Compatibility
The ScanGauge 3 is designed to work with OBD2 compliant cars.
Please make sure your vehicle is OBD2 compliant before purchasing.

Why Choose the ScanGauge 3?
The ScanGauge 3 is a practical upgrade for drivers who want live visibility of how their vehicle is performing every time they are on the road. With up to 9 live gauges on screen, built-in trip computers, fuel economy tracking, code reading, custom alarms, and free wireless updates, it offers far more than a basic code reader while remaining simple, compact, and easy to install. It is especially useful for drivers who want to improve fuel economy, monitor key engine data, or keep an eye on vehicle health without cluttering the cabin with multiple devices.
