Questions, answered.

Ask us a question

How much does a diagnostic check cost?

We’ll tell you the price of the diagnostic before we start. Electrical fault diagnosis is no fix, no charge: if we can’t find and fix the fault, you don’t pay.

How long does a diagnosis take?

Most faults are found within an hour or two. Intermittent faults can take longer, and we’ll keep you updated as we go.

Can you just reset my warning light?

We can clear a code, but the light will come back if the fault is still there. We find the cause first so it stays off.

Do you program ECUs and keys?

Call the workshop on 07 4630 1083 to check what we can do for your make and model.

Can I drive with the check engine light on?

If it’s flashing or the car is running poorly, stop and call us. If it’s steady and the car drives normally, book in soon so it doesn’t get worse.
