Do You Need a Diagnostic or Just a Service?
Warning light or odd behaviour — do you book a diagnostic or a service? A Cranbourne West specialist explains.
When it’s a service vs a diagnostic
A service is scheduled maintenance — oil, filters, fluids and checks — to keep a healthy car healthy. A diagnostic is investigation time to find the cause of a specific fault: a warning light, a noise, a performance issue.
If your car is simply due for maintenance, book a service. If something is wrong — a light, a symptom — that needs diagnostic time to pinpoint, because a service won’t find or fix a specific fault.
Why diagnostic time is worth it
Guessing at faults wastes money on parts that weren’t the problem. Our diagnostic time (from $363 for 2 hours) uses dealer-level equipment to find the real cause, so you only pay to fix what’s actually wrong.
