One of the most critical issues is the increased risk of engine damage leading to higher maintenance costs and truck repairs. Without the DPF filter in place, diesel engines accumulated soot and other particulates can build up on engine components and cause excessive wear to trucks.
Perhaps the most critical disadvantage of removing DPF is the increase in soot and particulate matter volume in the air. Besides, you will be more likely to be fined for removing DPF based on the regulations that governments pass for climate control.
Is it illegal to remove a diesel particulate filter? Yes, it is illegal. Owners face fines if caught and removing a DPF can also invalidate your car insurance policy.
DPF BENEFITS
Better fuel economy: Fuel economy is a big winner after deleting the DPF. Not only will a vehicle conserve the fuel that is utilized by the filter for regenerative purposes, but a cleaner running engine is also an engine that runs more efficiently.
Businesses who delete/modify DPF systems: A person who removes, disconnects or impairs the operation of an anti-pollution device fitted to a motor vehicle is guilty of an offence under the Protection of the Environment Operations Act 1997. On the spot fines of $1500 for a corporation and $750 for an individual applies.
A diesel particulate filter check has been part of the MOT test since February 2014. If a filter has been removed, the car will fail its MOT. Removing the DPF will sometimes cause the warning light to glow – and this itself is an MOT failure point: no dashboard warning lights should remain on during the test.
Aside from increasing your risk of being charged with motoring law violations, removing your DPF and EGR can improve your car's power, performance, and fuel efficiency.
Once the physical filter removal has been completed the ECU (Electronic Control Unit) is reprogrammed (Remapped) and any DPF related structures removed from the vehicles software. This will prevent the vehicle from sensing the missing filter and will prevent future DPF regeneration and DPF related warning lights.
You may also void the customer's insurance policy in the event of an accident, as the police report would find that the vehicle has been tampered with and is deemed un-roadworthy. Vehicles with time or kilometer-based regenerations that have not been tuned will try to regenerate even though there is no DPF present.
No. If a vehicle is in good mechanical condition and has been well maintained then removing the DPF will not result in a smoke test failure. However, a mechanical engine issue which results in the engine running too rich and producing excessive smoke could lead to a failure.
DPF, especially when clogged, affects airflow and causes delays in the exhaust process. Additionally, it affects the overall engine performance and power. When you remove the DPF, fuel flows better into the engine, boosting power generation and pressure. DPF delete is a sure way to increase engine horsepower.
In most cases, the automated software won't delete these parts of the file, but then leaving part of the DPF file in place will also bring problems such as the vehicle falling back into limp mode, the DPF light coming back on, excessive smoke and as a result of this, an MOT Failure.
Prices range from around $550 for a base tuner to more than $3,000 for a complete performance kit with DPF delete, cold-air intake, stainless down pipe plus other items. The good news is there are many ways to increase the power and performance of diesel pickups without breaking the law.
Australia's adoption of Euro 5 emissions standards in November 2016 necessitated a significant reduction in particulate matter emissions for diesel engines, and the most practical way for car-makers to comply with this standard was through the inclusion of a DPF device.
It is illegal to remove or a PDF.
Australian Design Regulations are contravened when you change the vehicle from the tested and approved designn NSW, individual fines are up to $11,000 and company vehicle fines up to $22,000 and the EPA are implementing similiar legislation across Australia.
Most drivers will opt for an ECU remap which removes the DPF system from the ECU entirely. This prevents the need for tricking the sensors as effectively the ECU no longer has any DPF control systems to worry about.
A DPF can last up to around 100,000 miles if maintained properly. After the car has exceeded that mileage, you could be looking at paying a large amount of money for a replacement - so always properly check MoT and service records when buying a used car.
We highly do not recommend anyone to remove their DPF filter and not replace it. If you are unsure how to replace a DPF filter than bring your vehicle to DPF solutions, having expert specialists replace your DPF at a high standard without the need to spend time doing it yourself.
Blocked DPFs wreak havoc with the delicate balance of your engine by preventing the normal venting of gases, which causes a variety of engine issues, as described above. In addition to reduced power and fuel efficiency, a blocked filter may eventually cause a dangerous mechanical malfunction and break your engine.
Engine Low on power. Engine cannot rev to high RPMS. Black smoke from exhaust upon acceleration. Odour of diesel fuel into the cabin.
Newer vehicles today perform automatic active DPF regeneration when the filter reaches a certain capacity of around 45%. The automatic DPF regeneration also happens for every 300 miles driven.
If you are noticing black smoke coming out of your diesel car then the chances are this is due to soot build up or the diesel particulate filter (DPF) cleaning itself. This could also result in a warning light flashing on your dashboard.
Usually this is due to one of two reasons - not enough air to burn the fuel, or not enough time for it to burn. In a tuned vehicle, fuelling is increased to make sure all of the air available is used up for maximum power.
Black or gray exhaust smoke
Gray or black exhaust smoke in a diesel engine could be indicate several problems: Wrong grade of fuel used. Clogged air filter. Improper timing.
If bluey-grey smoke leaves your exhaust while your vehicle is accelerating, this is usually the tell-tale sign of damaged piston rings. The parts are found in cylinders and can leak oil when they lose their seal. The fault is uncommon and will need the help of a professional to fix.
