Frequently asked

How long does a diagnostic take?

Most scans and basic tests take under an hour. Intermittent faults can take longer — we’ll keep you posted by SMS.

Do you work on 4WDs and trucks?

Yes — cars, utes, 4WDs, trucks, tractors and earthmoving gear, in the workshop or on site.

Can you come to me?

Our 24-hr mobile auto electricians cover Toowoomba and the Darling Downs — homes, worksites, farms and roadside.

Will it void my new-car warranty?

No. We follow manufacturer schedules and use quality parts, so your new-car warranty stays intact.

Book it in. We’ll sort it out.
