As environmental regulations tighten, diesel emission systems have become mandatory on all new diesel vehicles. Unfortunately, these systems can cause a host of problems for end users, requiring regular maintenance to operate efficiently and sometimes malfunctioning, causing the vehicle to go into pesky ‘limp-mode’. If you’re experiencing these issues, our diesel mechanics can diagnose and repair the problem quickly.
At Willy’s, we get to the core of emission issues, making sure your engine runs cleaner, works smarter, and stays fully compliant. With us, you’ll enjoy better fuel economy, reduced emissions, and a smoother ride.

DPF Repair, Replace & Off-Road Solutions
If you’ve lost power, found your diesel to be thirstier than usual or had your vehicle enter ‘limp’ mode, chances are there’s a problem with emissions system, specifically, your DPF, EGR or Ad Blue system. When this occurs, you’ve got a couple of options.
DPF Cleaning
DPF’s typically gets blocked after approximately 60,000 km, which decreases vehicle performance and raises fuel consumption. The most effective solution for a clogged DPF filter is to have it cleaned professionally.
DPF Replace
Replacing your DPF increases performance and improves fuel efficiency while keeping your vehicle compliant. Find out more below or get in touch to discuss your options.
Off-Road DPF, EGR & AdBlue Delete
On off-road, unregistered track vehicles only, we carry out DPF deletes, EGR deletes and AdBlue deletes — removing or bypassing the restrictive emissions hardware and retuning the ECU to suit. **This service is offered on off-road, unregistered track vehicles only — not for road-registered vehicles.** Road-registered? We can clean or repair your DPF, EGR or AdBlue system instead. Find out more below.
Why Emissions System Maintenance Matters
Emissions system maintenance is key to keeping your diesel running clean, powerful, and at its best. Regular servicing ensures peak performance, reduces pollution, and keeps you compliant with regulations.
Skip it, and you risk costly repairs and unnecessary downtime. With checks every 10,000 miles or 6 months, our team catches issues early – saving you both time and money.
Neglecting your emissions system can cause major damage, higher emissions, and even compliance headaches. That’s why we offer proactive solutions, including fuel filter replacements, DPF safe oil at services and off-road DPF solutions, to keep your diesel running smoothly and reliably.
From selective catalytic reduction to diesel exhaust fluid, every component matters in your engine’s performance. At Willy’s Workshop, we focus on the details that keep your diesel strong, helping you avoid costly fixes down the road.
What is a DPF Delete (Off-Road)?
On off-road, unregistered vehicles, a DPF delete (also called DPF removal) involves removing the Diesel Particulate Filter (DPF) from the exhaust system, then tuning the ECU to operate without the filter. We also carry out off-road EGR deletes and AdBlue deletes on unregistered track vehicles. The DPF is designed to catch soot and harmful particles in your diesel’s emissions, helping to keep your engine clean and meet regulations.
Over time, the DPF can get clogged up, reducing your engine’s performance and even causing problems with regeneration cycles. That’s where an off-road DPF delete steps in. It removes the filter and recalibrates the engine to run smoother and more efficiently. Please note, this service is only available on off-road vehicles. **Not all modifications are road legal, please check your state’s legislation for more info.**
Maximise engine power
At Willy’s Workshop, we specialise in optimising your off-road vehicle’s performance through expert engine recalibration, along with diagnosing and repairing pesky issues for a fraction of the cost. With improved airflow and precise tuning, you’ll enjoy faster acceleration, greater power, and a smoother, more responsive ride.
Save big on repairs
With years of experience of fixing these costly systems, ensure you get it fixed right the first time. Don’t spend $10,000+ at the dealer. We Can diagnose, maintain and effectively repair the systems eliminating costly DPF issues like blockages, failed regenerations, and sensor failures so your diesel runs strong and trouble-free.
Boost power & cut fuel costs
Ready to save on fuel? By fine-tuning your engine and remapping your vehicle effectively, we reduce backpressure and improve combustion efficiency giving you more power, better mileage, and lower fuel costs.
EGR Repairs & AdBlue Repairs
The DPF, EGR and AdBlue are solutions designed to reduce emissions. Unfortunately, these systems suffer similar problems, leading to poor performance, endless regen cycles, and higher fuel use. At Willy’s, we clear the blockages with expert diagnostics and cleaning, so your engine runs clean and efficient.
- EGR RepairThe biggest cause of EGR failure is the buildup of carbon from the exhaust, leading to clogged tubes and eventually causing the valves plunger mechanism to jam. In these instances, we’ll diagnose the cause of the problem, clear blockages and replace the valve — always using OEM parts or better.
- AdBlue RepairFaulty sensors, bad fluid, or system glitches can lead to poor performance or error codes. We recalibrate and repair your AdBlue system to keep your diesel in reliable condition, so you can keep your focus where it’s needed most.
Need your DPF or EGR cleaned or repaired rather than removed? See our dedicated DPF & EGR Cleaning & Repair service.

FAQ
Frequently asked questions
What is the purpose of an emission control system?
An emissions control system keeps your diesel’s emissions in check, reducing harmful pollutants like soot and NOx, and ensuring your engine stays compliant with regulations. It helps your engine breathe easier, run cleaner, and deliver better performance without hurting the environment.
What are the benefits of emission control for heavy duty vehicles?
For heavy-duty vehicles, having a solid emissions control system isn’t just about compliance – it’s about boosting performance and saving you money in the long run. Cleaner emissions mean fewer problems with your engine, better fuel efficiency, and a longer lifespan for your vehicle.
How does emission control work on a heavy-duty vehicle?
In a heavy-duty vehicle, the emissions control system works by trapping and neutralising harmful particles before they hit the air. It’s all about filtering out soot (thanks to the DPF) and breaking down NOx gases (with an SCR system) using a chemical reaction. These systems are constantly monitoring and adjusting to ensure your diesel runs efficiently.
How do I know if my diesel needs an emissions control upgrade?
If you’re noticing sluggish performance, poor fuel efficiency, or frequent regeneration cycles, it’s a sign your emissions control system might be due for a repair. A clogged DPF, insufficient NOx reduction, or other system issues can drag down your engine’s power and cost you more in fuel and repairs. At Willy’s Workshop, we’ll diagnose your system, and if an upgrade is needed, we’ll get you back on track with a solution that restores your diesel’s performance and keeps those emissions in check.
What does it mean when the emission control system light comes on?
If you’re noticing sluggish performance, poor fuel efficiency, or frequent regeneration cycles, it’s a sign your emissions control system might be due for an upgrade. A clogged DPF, inefficient NOx reduction, or other system issues can drag down your engine’s power and cost you more in fuel and repairs. At Willy’s Workshop, we’ll diagnose your system, and if an upgrade is needed, we’ll get you back on track with a solution that restores your diesel’s performance and keeps those emissions in check.
What causes a fault in the emission control system?
A fault in the emission control system is typically caused by:
Faulty Oxygen (O2) Sensor – Incorrect air-fuel mixture.
Bad Mass Airflow (MAF) Sensor – Affects fuel combustion.
Malfunctioning Catalytic Converter – Increases emissions.
Loose/Faulty Gas Cap – Causes fuel vapor leaks.
EGR Valve Issues – Impacts exhaust gas recirculation.
Vacuum Leaks – Leads to incorrect air-fuel ratios.
Dirty/Faulty Fuel Injectors – Causes poor combustion.
EVAP System Leak – Releases fuel vapors.
Bad MAP Sensor – Affects engine load regulation.
Failing ECM – Disrupts emissions control.
