A warning light, difficult starting, poor running, loss of power, unusual shifting or an intermittent electrical problem can have several possible causes. At our Whanganui workshop, a fault code is a starting point, not a parts order. We scan the relevant systems, test likely causes and explain what can be confirmed before recommending parts or repairs.
Diagnosis may include battery and charging tests, electrical checks, live data, mechanical tests or inspection of cooling, engine, transmission and driveline systems, depending on the symptom. Intermittent faults sometimes require extra test time or the fault to be present before a conclusive diagnosis is possible.
We agree the initial diagnostic scope and keep you updated before test time extends beyond the approved amount. You receive a practical explanation of what is confirmed, what remains uncertain and the recommended next step.
Vehicle condition, access, seized components, parts availability and the confirmed fault can change the work required. We explain material changes before proceeding.
