Engine Diagnostics in Mascot
Dealer-level scan tools and real diagnostic experience, used to find the actual fault behind a running, starting or performance issue.
Not every engine problem trips a warning light. Rough idling, hesitation under acceleration, poor fuel economy or a car that’s simply lost some of its usual pep can all point to an engine management fault that hasn’t yet escalated to a dashboard warning. Diagnosing these before they get worse usually saves money — and sometimes prevents damage to more expensive components down the line.
Our diagnostic process covers the engine management system, sensors, fuel delivery and ignition together, because a symptom in one area is often caused by a fault in another. We’ll walk you through exactly what we find and what it means before recommending any repair.

- Full engine management system diagnostics
- Fault finding on running, starting and performance issues
- Sensor, fuel delivery and ignition system testing

Engine Diagnostics — common questions
My car runs rough but there’s no warning light — can you still diagnose it? +
Yes. Many faults show up in live sensor data and driveability testing before they trigger a stored fault code, so a scan is worthwhile even without a warning light.
How long does an engine diagnostic take? +
Most diagnostic scans and test drives are completed within the hour, though intermittent faults can take longer to reproduce and confirm.
Is the diagnostic fee credited against the repair? +
Yes — if you go ahead with the repair we recommend, the diagnostic fee is credited against the total cost.
