In Maryborough and across regional Queensland, diesel vehicles are a way of life. Tradie utes, touring 4WDs, farm machinery, and light trucks all rely on the power, durability, and efficiency that diesel engines provide. But while diesels are built tough, they also require specialist knowledge when something goes wrong.

That is where Core Diesel makes the difference. Our workshop has become a trusted name in the Maryborough community by combining advanced technical skills, quality workmanship, and a real understanding of how locals use their vehicles. From minor servicing to complex repairs, our team is committed to getting your diesel back on the road and keeping it running at its best.

1. Diesel-Focused Expertise

Not all mechanics are equal when it comes to diesel engines. Diesels operate at higher pressures, rely on precise injection systems, and often include turbochargers and emissions systems that need expert attention. At Core Diesel, our technicians specialise in diesel every day. This focus means we know how to diagnose and repair problems that other workshops might miss.

Our experience covers a wide range of diesel vehicles, from modern common-rail systems to older mechanical engines. Whether it is a 4WD struggling with power loss, a tradie ute with a blocked DPF, or a light truck showing injector issues, we have the knowledge and tools to provide the right repair.

2. Advanced Diagnostics That Save Time and Money

One of the biggest challenges in diesel repairs is finding the true cause of a problem. Many faults hide behind generic warning lights, rough idling, or loss of power. Guesswork often leads to unnecessary parts being replaced without solving the issue.

Core Diesel uses advanced diagnostic equipment to read live data from your engine and ECU. We can track fuel pressure, boost levels, exhaust temperatures, and injector performance in real time. By combining this data with our hands-on experience, we can pinpoint faults quickly and accurately. This approach means fewer delays, less wasted money, and a faster turnaround for your vehicle.

3. Comprehensive Repair and Servicing Capabilities

Our workshop is equipped to handle everything from routine servicing to complex diesel repairs. That includes injector testing and replacement, turbocharger repairs, DPF and EGR cleaning, intake system servicing, and full fuel system diagnostics.

We also provide preventative services that keep your diesel healthy, such as carbon cleaning, dyno tuning, and detailed inspections before major trips. By covering all aspects of diesel care under one roof, we save you the hassle of running between multiple workshops.

4. Repairs Tailored to Real-World Use

Every diesel vehicle in Maryborough has a different job. Some tow heavy caravans across Queensland highways, others spend long days idling on construction sites, while many are relied on for farm or commercial use. That is why we do not treat every diesel the same.

At Core Diesel, we ask about how you use your vehicle before recommending a repair or service. This allows us to provide solutions that work in real conditions, not just on paper. For example, we might adjust servicing schedules for vehicles that tow frequently, or recommend intake cleaning earlier for 4WDs used in dusty environments. This tailored approach gives you reliability where it matters most.

5. Commitment to Quality and Transparency

Trust is important when choosing a diesel repair workshop. At Core Diesel, we believe in clear communication and honest advice. We take the time to explain what we find, why it matters, and what your options are. There are no surprise invoices or unnecessary work.

• We use high-quality parts and fluids that are specifically designed suit Australian conditions.
• We keep detailed service records so you know exactly what has been done.
• We provide maintenance reminders to help you stay ahead of problems.

By combining professionalism with transparency, we build long-term relationships with our customers, rather than treating repairs as one-off jobs.
