Engine Diagnostics and Repairs in Ringwood
Modern vehicles rely on complex computer systems to manage engine performance, emissions, and safety. When something goes wrong, your car’s onboard computer stores diagnostic trouble codes (DTCs) that pinpoint the issue. At Heatherdale Automotive, we use professional-grade diagnostic equipment to quickly identify and resolve engine problems.

Why Professional Diagnostics Matter
A fault code alone does not tell the full story. For example, a “P0420 — Catalytic Converter Efficiency Below Threshold” code could be caused by a failing catalytic converter, a faulty oxygen sensor, an exhaust leak, or even bad spark plugs. Our experienced mechanics interpret the data in context, perform additional testing when needed, and identify the actual root cause — saving you from unnecessary parts replacement.
Frequently Asked Questions
How much does a diagnostic scan cost?
A standard diagnostic scan at Heatherdale Automotive is competitively priced. If you proceed with repairs, the diagnostic fee is typically applied to the repair cost.
My check engine light is flashing — is this serious?
Yes. A flashing check engine light indicates a severe engine misfire that can damage your catalytic converter. Reduce speed, avoid heavy acceleration, and get to a mechanic as soon as possible.
Can you diagnose European cars?
Yes. Our diagnostic equipment supports all major European, Japanese, Korean, and Australian vehicle makes including Toyota, Mazda, Hyundai, Volkswagen, BMW, Mercedes, Audi, and Ford.
