At Yarra Valley Diesel, we combine technical know-how with a passion for problem-solving. With years of hands-on experience, we take pride in providing honest, efficient, and high-quality service for all diesel vehicles.
From precision fault-finding to bespoke performance maps, we cover every diesel platform—and we’re the ZD30 Patrol specialists. Wherever you are, our mobile tuner will:
Torque is the ability to transform engine power into wheel motion—your “pull force.” More torque means greater efficiency. Diesels shine at low revs, delivering strong pull with less throttle, which yields:
Reduced fuel burn
Sharper throttle response
Enhanced safety
Combine increased torque with more power, and the difference is noticeable from the very first drive.
Experience the synergy of torque and power with our custom tuning—feel the 30% uplift from your very first ride.
Our Dyno Custom Tuning provides an average power increase of 20% at the wheels.
We unleash the real power of your Diesel engine within manufacturer’s limits.
This is a typical Dyno test before/after:
If more torque gives that less throttle is needed to maintain same cruising speed, it means that less fuel is needed.
With our ECU Remap you will save between 10% to 20% in fuel consumption.
A common question is: How safe is your tune?
Here’s our best answer:
A “diesel tuner” is like a “doctor for cars.” When your car isn’t running well, you bring it to a tuner—just as we humans visit a doctor when we don’t feel well.
What makes a doctor “safe”? A few key factors:
Experience (usually, the longer, the better)
Specialized diagnostic tools (top-level equipment is a plus)
Facilities (a state-of-the-art workshop makes a big difference)
Teamwork (combined expertise is better than just one person)
References (knowing how previous “patients” fared is invaluable)
A diesel tune is considered “safe” when all of these factors are at their best.
EGR (Exhaust Gas Re-circulation) valve is present in every recent diesel vehicle.
Is quite common that this valve gets blocked causing engine’s malfunctions.
If your EGR valve is causing loss of power or your engine light is on, please get in touch with us today to avoid expensive repairs.
We offer EGR repairs and delete service (via ECU).
Since 2009 Diesel Particulate Filters are installed in every diesel vehicle sold in Australia.
Vehicles with limited highway cruises are more than likely to face a DPF blocked, causing engine’s malfunctions and repairs needed.
We offer DPF cleanings using state-of-the-art equipment and DPF repairs via ECU (off-road only).
AdBlue is a liquid-like material used to clean exhausting gases going in the atmosphere, the same functionality of the EGR valve and in many cases this system can stop working properly causing engine’s faults.
If your AdBlue system is facing issues, please get in touch with us today to avoid expensive repairs.
We are specialised in AdBlue repairs and AdBlue repairs (off-road only) via ECU.
Our goal is to increase vehicle performance and efficiency. The first and most important step is to diagnose the vehicle. A modern diesel vehicle is a perfect balance of electrical and mechanical parts—a small malfunction can easily lead to loss of power, black smoke, engine or turbo failures, etc.
We bring your vehicle into our Dyno Room, where our highly experienced technicians begin the inspection.
Under the bonnet – (pipes, oil leaks, etc..)
Wheels and suspension – (will affect Dyno readings)
Exhaust system,
Intake system (could be clogged by carbon residue).
Once the visual inspection is complete, we scan your vehicle’s computer to ensure there are no other underlying issues.
If we spot any issue we are able to address it and solve it.
This stage is crucial for a tuning to be considered as “safe”.
