Fault finding &
diagnostics.

Overview

Modern vehicles are running computers — sometimes 50 or more of them. When something goes wrong, the warning light on your dash is rarely the full story. Codes can be misleading, sensors can fail in subtle ways, and the right fix often depends on reading live data while the fault is happening.

Our diagnostic process combines manufacturer-grade scan tools, multimeters, oscilloscopes and wiring diagrams with hands-on experience across petrol, diesel and hybrid vehicles. We work the problem methodically — we don't just throw parts at it and hope.

What we diagnose

• Check engine, ABS, airbag, traction-control and other warning lights
• Intermittent stalling, misfires, rough running and starting problems
• CAN bus and communication faults
• ECU, BCM and module-level issues
• Sensor faults — O2, MAF, crank/cam, temperature, pressure
• Immobiliser and key/security system problems
• Pre-purchase electrical inspections

When you need this

• A warning light has come on (or keeps coming back)
• The vehicle has an intermittent fault that's hard to pin down
• Another shop has replaced parts but the problem persists
• Buying a used car and want it electrically checked first
• You've been told it's a major repair and want a second opinion

Our process

We start with a full scan of every module in the vehicle and capture both stored and pending fault codes. Then we interpret those codes properly — checking live data, freeze-frame data, and the actual wiring and sensor behaviour. Only once we've confirmed the real cause do we quote the fix. You'll get a clear explanation of what's wrong and exactly what's needed to put it right.

Why us for diagnostics

Fault finding is what we do most. Anyone can read a code, but interpreting it correctly takes proper training, the right tools, and the experience to know when the code is lying. We've seen the trickiest electrical gremlins and we don't give up until the fault is properly identified.
