Why Toowoomba trucks need this work
Most Toowoomba trucks that come to us for diagnostics arrive with a code that's already been read somewhere else. The code tells you which circuit complained, not what caused it. On a 6.7 Cummins, 6.6 Duramax or 6.7 Power Stroke, the same code can mean a sensor, a wiring chafe, a fuel-quality issue or a DPF that never completed a regeneration — and only live data under load separates them.
What's included
- Factory-level scan tool access, not generic OBD-II code pulling
- Live data logged under road load, not just at idle in the workshop
- Wiring, connector and earth checks on intermittent electrical faults
- Fuel system and injector performance testing on diesels
- Written findings with a quote before any repair work starts
| Symptom | Common real cause | What we check |
|---|---|---|
| Limp mode under load | Boost leak or turbo actuator | Live boost vs commanded, actuator sweep |
| Repeat DPF light | Interrupted regens from short trips | Soot load, regen history, exhaust temps |
| Rough idle / misfire | Injector balance or fuel quality | Injector return, balance rates, fuel test |
| Random electrical faults | Corroded earth or chafed loom | Voltage drop testing, loom inspection |
Getting here from Toowoomba
Our workshop is at 46 Regent St, Caloundra — 2 hours 30 minutes from Toowoomba. Most Toowoomba customers drop the truck off in the morning and collect it the same day where the job allows, so truck diagnostics doesn't cost you a second trip. If you're coming in from Highfields, Oakey and Pittsworth, call ahead and we'll have the hoist free when you arrive.
Fixed-price minor servicing starts at $469 (1500-series) and $599 (HD-series). All other work — including diagnostics & fault finding — is quoted before we start, with no surprises on the invoice.
Frequently asked questions
- Another workshop in Toowoomba couldn't find my fault — can you?
- Usually, yes. Most 'no fault found' results come from generic tooling that can't see American-truck-specific live data. We road-test with the truck loaded and log the data the fault actually appears in.
- Do I pay for diagnostics separately from the repair?
- Diagnostic time is quoted upfront and is separate from repair labour, so you know what the investigation costs before we start. We give you the findings in writing either way.
- Do you service trucks from Toowoomba and the Darling Downs?
- Yes. It's around two and a half hours, so we book Downs customers as a single comprehensive visit covering servicing, diagnostics and inspection in one trip.
- How far west do you take customers from?
- We regularly see trucks from a few hundred kilometres west and north-west of the coast, including the Darling Downs, South Burnett and Somerset regions.
