Car Diagnostics That Find the Real Fault
A warning light tells you something's wrong, not what. At Fangio Auto we use proper diagnostic equipment to read and interpret your car's fault codes, then test to confirm the real cause before quoting any repair, so you don't pay to replace the wrong part.

What We Do
Car Diagnostics at Fangio Auto
A fault code is a starting point, not an answer. We read it, then diagnose properly.
Live Data Testing
We watch sensors and systems in real time to confirm what the code is actually telling us.
ABS, Airbag & Body Systems
Diagnostics aren't just engine. We read ABS, airbag, body and comfort-system faults too.
Drivability Faults
Misfires, hesitation, limp mode and rough idle traced to the actual cause.
Pre-Repair Diagnosis
We confirm the fault before any parts are replaced so the repair is right the first time.
Post-Repair Verification
After a repair we clear and re-scan to confirm the fault is gone and won't return.

A check-engine or warning light on the dash

Car Diagnostics - FAQs
What does a car diagnostic actually do?
It reads the fault codes stored by your car's computer and lets us see live sensor data. That points us in the right direction, but we always test to confirm the real cause before recommending a repair.
My warning light is on but the car drives fine. Should I worry?
It's worth checking. Some faults are minor, but others (like a failing sensor or an emissions issue) can get worse and more expensive if ignored. A diagnostic tells you how urgent it is.
Will clearing the code fix the problem?
Usually not. Clearing a code only switches the light off temporarily. If the underlying fault is still there, the light will return. We diagnose and fix the cause, then clear and verify.
Do you diagnose all makes?
Yes. We diagnose petrol and diesel vehicles across most makes and models at both branches. If your car needs a specialist tool we don't have, we'll tell you upfront.
Where are you based?
Two branches: Randburg (Johannesburg) and Hermanus (Overberg). Pick your nearest branch on our contact page.
