About our range of car diagnostic tools

Is your car not firing on all cylinders? Are its faults driving you round the bend? Simply plug in one of our diagnostics scanners and you’ll soon discover what the problem is.

How do car diagnostic scanners work?

Diagnostic scanners interact with the computer chip inside your car, assessing your car’s internal health. If there are any problems, you’ll see a unique code that will tell you what the problem is - and what you need to fix. In seconds, you’ll learn what it could have taken hours, days, or even weeks to figure out on your own.

OBD2 scanners

Our OBD2 scanners are compatible with all vehicles from 1996 onward that are OBD2 and EOBD compliant. They feature a backlit LCD display that is easily read even at night, and can turn off engine malfunction signs while telling you exactly what needs fixing on your vehicle.
