Why Dalby trucks need this work
Most Dalby 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 Dalby
Our workshop is at 46 Regent St, Caloundra — 3 hours from Dalby. Most Dalby 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 Chinchilla, Jandowae and Bell, 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 Dalby 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.
- Is Dalby too far to service an American truck at your workshop?
- It's about three hours, and plenty of Western Downs owners make it a planned single-visit trip. We book the day around getting everything done and quoted before you head back.
- Do heavy-duty trucks working out west need extra cooling?
- Often yes. Sustained maximum loads in high ambient heat push transmission and engine cooling hard — we assess whether an auxiliary transmission cooler is worthwhile for your actual workload.
