Diagnostics & Fault Finding in Sunshine Coast

We diagnose warning lights, limp mode, rough running and electrical faults on American trucks for Sunshine Coast owners using factory-level scan tools — not a generic code reader. If a general mechanic has already handed your truck back with "no fault found", this is the workshop that finds it.

Why Sunshine Coast trucks need this work

Most Sunshine Coast 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
SymptomCommon real causeWhat we check
Limp mode under loadBoost leak or turbo actuatorLive boost vs commanded, actuator sweep
Repeat DPF lightInterrupted regens from short tripsSoot load, regen history, exhaust temps
Rough idle / misfireInjector balance or fuel qualityInjector return, balance rates, fuel test
Random electrical faultsCorroded earth or chafed loomVoltage drop testing, loom inspection

Getting here from Sunshine Coast

Our workshop is at 46 Regent St, Caloundra — central to the coast from Sunshine Coast. Most Sunshine Coast 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 Caloundra, Kawana and Maroochydore, 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 Sunshine Coast 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 American trucks from anywhere on the Sunshine Coast?
Yes — we regularly see trucks from Caloundra to Noosa and out to the hinterland around Nambour, Maleny and Beerwah.
Why can't my local Sunshine Coast mechanic service my RAM or Silverado properly?
Most general workshops lack the imperial tooling, correctly rated hoists, and factory-level diagnostic access these trucks need. It's not about willingness — it's equipment and training specific to US-spec vehicles.
