Diesel Particulate Filters (DPFs) are expensive—often ranging from $ 1 , 500 $ 1 , 5 0 0 to over $ 6 , 000 $ 6 , 0 0 0 —primarily due to the use of precious, rare metals like platinum and palladium in their construction, complex manufacturing processes, and the integration of sensitive electronic sensors. Their high cost also reflects the need for specialized diagnostic labor and the rigorous, regulated emission standards they must meet.
For passenger cars, the cost of replacing a DPF can range from AUD 1,500 to AUD 3,000 or more. Larger vehicles like buses and trucks could have significantly higher costs due to the larger size and more complex systems. For buses and trucks, the cost could range from AUD 3,000 to AUD 10,000 or more.
In most cases, failed or damaged DPFs and DOCs have value because they are coated or “catalyzed” with Platinum Group Metals (PGM). Because of this value, they should be recycled by a reputable recycling company to ensure the PGM is recovered for use in other products.
No. The system will detect the lack of the DPF and not operate. The system uses pressure differential to monitor the state of the DPF. Without the DPF there is no differential. There are software modifications to get around this but if you get caught you could find that to be quite expensive.
Top 10 vehicles with DPF issues:
A diesel particulate filter on a poorly serviced car may fail sooner than a well maintained one, generally, they should last for at least 100,000 miles. It's important you use the right type of oil as well – some oils contain additives that can actually block filters.
Does my car have a DPF? If it was built after 2009 then it will do. All diesel cars since September 2009 have to be fitted with a DPF in the exhaust to stop this soot passing into the atmosphere. It's part of the Euro 5 standard for diesels but be aware that some cars built before this date also come with DPFs.
No, DPF (Diesel Particulate Filter) deletion is illegal for road-registered vehicles in Australia, as it violates Australian Design Rules (ADRs) for emissions and renders the vehicle unroadworthy, leading to potential fines, defect notices, and voided insurance. While some owners do it for performance, it's only permitted for specific off-road, racing, or industrial uses where ADR compliance isn't enforced, and it carries significant legal risks for on-road driving.
A very common way to begin cleaning a DPF is to use high-pressure, compressed air. You can achieve this best by using a high-pressure cleaning cabinet, which backflush compressed air into the filter and forces ash to dislodge any blockage.
Too much idling cools the exhaust system, leading to a blocked diesel particulate filter. Don't turn off your engine during active regeneration or you risk clogging the DPF. Stick with OEM-approved oil to avoid ash buildup that clogs the DPF filter.
Yes. Reconditioned units supplied by DPF Clean Team are original equipment manufacturer (OEM) parts that have been properly cleaned, tested and inspected. Each unit is checked for structural integrity, restored using approved processes and tested to confirm performance.
If your DPF is heavily clogged, replacement is likely the best option. In severe cases, cleaning may not be effective at removing all the soot, and a replacement filter is necessary to ensure proper engine performance and emissions compliance.
A1: The cost typically ranges from $3,000 to $10,000, depending on your vehicle's make, model, and local labor rates. Q2: Is it worth doing a DPF delete? A2: If you value improved performance, better fuel efficiency, and reduced maintenance, a DPF delete can be worth it.
You should consult the handbook for your vehicle for more specific guidance on how you should drive to initiate regeneration of the DPF and clear the warning light. Nevertheless, a general rule of thumb to follow is that you should run the engine at least 40 mph and at least 2500 rpm.
Note: cars registered after the 1st May 2010 require a fully functioning DPF to pass a WOF. Cars with a DPF delete, registered after this date, will not pass a WOF. Exhaust Gas Recirculation or EGR is a process whereby a certain percentage of exhaust gases are passed through the engine inlet to be re-combusted.

If your car has an automatic gearbox, change gears in manual mode, increasing the number of revolutions. However, there's no need to go as far as the rev limiter, as that won't do any good. Drive in this mode for at least 30 minutes. This will trigger a regeneration cycle and your DPF will be cleaned.
Generally, it's best to avoid driving your car with the DPF light on for more than a few miles. If you're unsure of how long you can drive your vehicle with the warning light on, it's best to consult your owner's manual or a qualified mechanic.
There are two main types of DPF regeneration: passive and active, however, DPF regeneration can be performed manually using a scan tool.
You should buy a diesel car in 2025 if you do high-mileage, long-distance driving or need heavy towing, as they offer superior fuel efficiency and durability for such tasks, but it's less ideal for short city trips where hybrids/EVs are better, and you must consider potential future urban restrictions and the ongoing maintenance of complex emissions systems (AdBlue, DPFs). While new diesel production is slowing, modern diesels are cleaner, but consider used Euro 6 models or leasing (PCP) to mitigate depreciation concerns as the market shifts towards electrification, with bans on new sales generally targeted for 2035.
Australia's "25-Year Rule" allows importing classic and collectible vehicles (cars, motorcycles, light commercials) older than 25 years, under the Road Vehicle Standards (RVS) laws, by obtaining a Concessional RAV (Register of Approved Vehicles) approval to avoid strict compliance with modern Australian Design Rules (ADRs). This "rolling" rule means the vehicle must be at least 25 years old at the time of application, simplifying imports for enthusiasts but still requiring compliance with ADRs relevant to its original build year, plus some modifications for safety like VINs or child restraints.
Summary. Sales of new petrol and diesel vehicles are being banned in the ACT by 2035. ICE vehicles are being phased out as manufacturers pivot to making EVs and lenders stop offering loans for them. Driving and refuelling your petrol car beyond 2035 will still be possible.
The worst things for a diesel engine involve neglecting maintenance (especially oil/filters), using poor fuel quality, allowing low fuel levels, overloading/lugging the engine, and not letting it warm up/cool down properly, all leading to contamination, excessive wear, turbo damage, and injector/pump failure due to high pressures and sensitive components. Contaminated fuel (water, dirt, high sulfur) is especially damaging, corroding parts and clogging filters in these high-pressure systems.
Improved Efficiency – By reducing NOx emissions, AdBlue helps improve engine efficiency and performance. Longevity of DPF System – AdBlue works alongside your DPF to ensure the exhaust gases are cleaner, reducing the harmful particles that cause DPF blockages.
If a diesel car is used for short journeys and only in town, it might not reach proper operating temperature, which can lead to improper regeneration and soot build up.
