Engine Diagnostics & Check-Engine Light

Randwick Auto Electrics uses dealer-level scan tools and years of experience to read your engine's fault codes, interpret the live data, and tell you exactly what's wrong.

What engine diagnostics can uncover

  • Oxygen, MAF and MAP sensor faults
  • Misfires, rough idle and hesitation
  • Faulty ignition coils and spark plugs
  • Emissions and catalytic converter codes
  • Throttle body and idle control problems
  • Intermittent stalling and limp-mode faults

More than just reading a code

A fault code is a starting point, not an answer. We interpret the code alongside live sensor data and your car's symptoms to find the true cause — so you don't replace a perfectly good sensor when the real issue is a wiring fault or a vacuum leak.

Serving Randwick, Bondi, Coogee, Maroubra and the wider Eastern Suburbs, our team is ready to help. Get in touch or call 02 9398 7888 to book your car in.

Frequently Asked Questions

The check-engine light is flashing — is that serious?

A flashing light usually means an active misfire that can damage your catalytic converter. Reduce speed and book it in promptly. A steady light is less urgent but still worth diagnosing.

Doesn't the auto-parts store read codes for free?

They can read the code, but reading and diagnosing are different things. We use that code as one clue among several to find the actual fault, which saves you replacing the wrong parts.

Will the light reset itself?

Sometimes a minor issue clears on its own, but if the light keeps returning there's an ongoing fault. We can read pending and stored codes to see what's really going on.
