Modern scan tools, decades of know-how — faults found, not guessed.

About this service

Auto Electrical & Diagnostics

A warning light on the dash tells you something is wrong — it doesn't tell you what. We run dealer-level diagnostic equipment across European and Asian brands, which means we read what the car is actually reporting and test from there, instead of swapping parts and hoping. Batteries, alternators, starter motors, wiring faults and those maddening intermittent electrical gremlins all get the same methodical treatment.

Auto Electrical & Diagnostics FAQs

Common questions from Newcastle and Lake Macquarie customers about auto electrical and diagnostics.

My check engine light is on but the car drives fine — is it urgent?

Get it scanned soon rather than ignoring it. Some faults are minor, but others quietly cause damage (or leave you stranded) if left. A scan takes minutes and tells us whether it's a drive-it-in-Monday problem or a stop-driving-it problem.

How do I know if it's the battery or the alternator?

Both cause similar symptoms — slow cranking, dim lights, a car that needs jump starts. We test the battery, charging voltage and starter draw together, so you replace the part that's actually faulty, not both.

Can you diagnose electrical faults on European cars?

Yes — we carry diagnostic tooling that covers BMW, Audi, Mercedes-Benz, VW and Skoda systems properly, not just generic OBD readers. That's often the difference between finding a fault and chasing it for weeks.
