Coffs Harbour Car Diagnostics
When a warning light pops up or your vehicle just isn’t performing like it should, diagnostics are your first step to understanding what’s really going on. At Advanced Automotive Services in Coffs Harbour, we use modern, high-quality car diagnostic tools to pinpoint faults quickly and accurately. From engine warning lights and misfires to sensor failures and transmission faults, we can detect and diagnose problems that aren’t always visible with a basic inspection. It saves you time, reduces guesswork, and prevents unnecessary repairs—because knowing exactly what the issue is means we can fix it the right way, the first time.
Our certified mechanics have experience across a wide range of vehicles, including 4WDs, performance models and European brands, so you can be confident in the results. If you’ve got a light flashing on your dash or something just doesn’t feel right, call us on
(02) 5619 2870 to book your diagnostic check.

Smart Inspections that Save Time
Diagnostics today go far beyond a quick visual check. Your car’s onboard computer system constantly monitors performance, fuel use, emissions, and dozens of components—and when something's off, it stores fault codes that only a scan tool can read. We connect directly to your vehicle’s system to retrieve these codes, then interpret them using our experience and manufacturer specifications. But we don’t stop there. We combine scan results with physical inspections and test drives to ensure we understand the full picture before recommending any work.

Whether it’s an intermittent issue, unusual noise, or drop in fuel efficiency, diagnostics help us trace it back to the source. You’ll receive a clear explanation of what’s wrong, what needs fixing, and how to avoid further problems. If your car’s not running like it should, let’s take a closer look—book your diagnostic scan today and drive away with confidence.
FAQ
Everything You Need To Know
What does a car diagnostic test check for?
A diagnostic test checks your vehicle’s electronic systems and sensors for faults. It identifies issues with the engine, transmission, exhaust, brakes, airbag system, and more. The scan tool reads trouble codes from the car’s computer (ECU), which can help pinpoint specific problems such as misfires, faulty oxygen sensors, or timing issues. It’s a key tool for modern vehicle maintenance and repair.
Can I ignore a warning light if the car still runs fine?
It’s not recommended. Warning lights indicate that something isn’t working correctly, and ignoring them can lead to more serious (and expensive) damage. Even if your car appears to be running normally, underlying faults—such as reduced fuel efficiency, poor emissions, or engine stress—may be occurring. A quick diagnostic scan can clarify what’s happening and help prevent bigger issues later.
Is a diagnostic test covered in regular servicing?
Basic scans may be included in scheduled servicing, but a full diagnostic is usually a separate service—especially when investigating a specific problem. If a warning light is active or you’ve noticed performance issues, a dedicated diagnostic appointment allows for a more thorough investigation, helping to prevent future breakdowns or repairs.
