Mercedes-Benz Sprinter Diesel Tuning & Servicing
The Mercedes-Benz Sprinter is the benchmark commercial van in Australia, serving as everything from a courier workhorse and trade vehicle to a long-haul motorhome platform. Across its generations it has carried three core diesel engines: the long-serving OM651 2.1-litre four-cylinder, the muscular OM642 3.0-litre V6, and the current-generation OM654 2.0-litre four-cylinder fitted to the VS30 Sprinter from 2019 onward. Each has its own character, its own strengths and its own well-documented weak points, which is exactly why specialist knowledge matters when it comes to getting more from one or keeping it on the road.
At Willy’s Workshop we work on Sprinters as both a performance and a mechanical proposition. A loaded van or a heavy camper conversion places very different demands on a drivetrain than a passenger car, and a one-size-fits-all approach simply does not cut it. Whether you want sharper throttle response and stronger pulling power for towing and freight, or you are chasing down a DPF warning, an EGR fault or an AdBlue (SCR) issue, our team understands how these engines actually behave in real Australian operating conditions.
Operating from our Oxley workshop in Brisbane and our Warana workshop on the Sunshine Coast, we combine custom in-house ECU tuning with full diesel mechanical repair. Every tune is built to suit your specific engine, your duty cycle and your factory hardware, then dyno-verified before it leaves the building so you can see exactly what your Sprinter is producing.

Your Sprinter's tune potential
Pick your engine to see typical gains from a Willys Workshop tune.
Indicative gains on a stock vehicle, measured on a dyno at the engine (crank) — wheel power reads lower (typically 15–20% on a 4WD). Actual results vary with vehicle condition, fuel quality and modifications.
Indicative rear-wheel (dyno) figures with switchable maps, emissions intact. Actual results vary with vehicle condition, fuel quality and modifications.
Why choose Willy’s for your Mercedes-Benz Sprinter
Performance Tuning
Custom, in-house ECU tuning developed for your Sprinter’s engine and how it is actually used
- Custom ECU tuning written in-house for the OM651, OM642 V6 and OM654, never a generic off-the-shelf file, with calibration matched to your van’s duty cycle
- Real-world drivability gains where they matter for a working van: stronger low-to-mid range torque, smoother throttle response and easier towing and freight pulling
- Calibration developed around your factory hardware and turbo setup, with sensible limits that respect the engine, transmission and emissions equipment
- Every tune dyno-verified on our in-house dyno so power and torque outputs are measured and documented, not estimated
Servicing & Repair
Full diesel mechanical servicing and repair for high-kilometre commercial Sprinters
- Logbook-style servicing, fluid and filter changes and correct diesel-spec oil to keep timing chain wear and engine longevity in check
- DPF diagnosis, forced regeneration and cleaning, plus investigation of the frequent regeneration and blockage issues these engines are known for
- EGR system diagnosis and carbon-related fault rectification, including the sticking valve and intake build-up common on the OM651
- AdBlue / SCR system fault-finding, injector seal seepage (‘black death’) diagnosis, and timing chain and tensioner inspection on high-kilometre vans
