Repairs That Go The Distance

Accurate Fault Finding Backed By Experience

Today’s vehicles are full of computers, sensors and complex electrical systems — which means when something goes wrong, a scan tool is just the beginning. Our diagnostic process combines ECU scanning, live data monitoring, and hands-on testing to accurately pinpoint issues. From misfiring engines and gearbox errors to ABS faults and hybrid system warnings, we diagnose problems others miss.


Once we’ve found the fault, we’ll explain what’s causing it, how urgent it is, and what your repair options are — with no pressure and no upselling. We can also clear stored codes after repairs, reset service lights, and ensure your vehicle is running as it should. Whether you’ve been dealing with a long-standing fault or just want peace of mind before a road trip, our diagnostics service is a smart first step.

Frequently Asked Questions

  • What is a car diagnostic test?

    A diagnostic test uses a scan tool connected to your vehicle’s onboard computer to check for trouble codes. It helps identify problems with the engine, transmission, exhaust system, sensors, and more. Mechanics can then use this information to pinpoint the root cause of issues.

  • Can I ignore a warning light if my car seems fine?

    That's not a good idea. Many faults don’t show immediate symptoms but can lead to breakdowns or long-term damage if left unchecked. Diagnostic testing can catch minor issues before they become major repairs — even if your car still seems to drive normally.

  • Can you diagnose faults in older vehicles without OBD?

    Yes. Vehicles built before around 1996 often lack standard OBD ports, but experienced mechanics can still diagnose issues using traditional fault-finding methods. This includes visual inspections, manual testing, vacuum checks, timing light diagnostics, and listening for irregular noises. For older engines, a mechanic’s experience is often more important than a computer scan. At a well-equipped workshop, even classic and vintage vehicles can be accurately diagnosed and repaired.
