Whether you’re planning a lap around Australia or heading up the coast for the weekend, your motorhome is more than just a vehicle. It is your home, your escape, and your travel partner. When it breaks down, the disruption affects more than just your schedule. That is why diesel motorhome servicing needs to be taken seriously.
At Core Diesel in Maryborough, we specialise in diesel engine diagnostics, performance tuning, and maintenance services designed to keep your motorhome reliable and ready for the next big trip.
Why Diesel Motorhomes Need Dedicated Servicing
Diesel engines are built to last, but motorhomes present some unique challenges. These vehicles are heavy, often towing extra weight, and spend extended periods idling or cruising at low speeds. These conditions can lead to premature wear and poor combustion if the engine is not adequately serviced.
Regular driving does not always mean healthy engine performance. If you are doing short runs between campsites or spending hours at low RPM, carbon and soot can build up inside the intake system and emissions components. This results in poor fuel economy, sluggish performance, and long-term damage if left unaddressed.
Common Issues in Diesel Motorhomes
Even when your motorhome starts and runs, that does not always mean it is working at its best. At Core Diesel, we regularly help motorhome owners resolve issues such as:
- Reduced power on hills or when towing
- Excess black smoke or poor emissions
- Rough idle or vibrations at low speeds
- DPF warnings or frequent regenerations
- Overheating during extended highway driving
These problems often creep in slowly and go unnoticed until they affect comfort and reliability.
What Every Motorhome Service Should Include
Diesel servicing is not just about changing oil and filters. For motorhomes, it is also crucial to inspect the systems that handle heavy loads, operates for extended periods, and work at low speeds. At Core Diesel, our services include:
- Intake cleaning to remove carbon deposits
- EGR and DPF system inspection and cleaning
- Turbo and fuel injector performance checks
- Cooling system pressure tests and coolant condition
- Battery load testing and alternator function
- Dyno tuning for better efficiency when towing
We also perform ECU diagnostics to scan for hidden faults, even if no warning lights are on. This helps us catch issues early and prevent mid-trip failures.
How Often Should You Service a Diesel Motorhome?
The best time to service your motorhome is before a trip, not after it breaks down. We recommend:
- Every 10,000 to 15,000 kilometres
- Or every 6 to 12 months, even if the vehicle has been parked
- Before any major road trip or change in driving conditions
If your motorhome has not been driven in months, its fluids may have degraded, and its electrical components may require inspection. Servicing on time helps maintain resale value and avoids surprise costs on the road.
