Do all diesel cars have DPF? Since 2009, manufacturers of diesel cars have been legally required to fit all diesel cars with DPFs, so all modern diesel cars have DPFs installed.
All diesels built from 2009 onwards will have a DPF, and some diesels built before this will have one as well. As long as you drive longer distances at least a couple of times a month, your DPF should have plenty of opportunities to regenerate itself.
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. This can lead to serious engine problems down the road with expensive repair costs.
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.
We seem to get fewest reported problems from Hyundai/KIA 1.6 CRDIs and Renault/Nissan/Mercedes 1.6 dCi 130s.
Car fleets name the Mazda 6 as the most problematic vehicle fitted with a DPF, with 21% of enquiries coming from this model. The BMW 120, 320 and 520 series comes a close second with 13% of enquiries. BMW 330 and 530 models also made the top five.
Since DPFs and EGRs effectively reduce engine performance by obstructing your exhaust and diluting the fuel/air mix in your combustion chambers, removing them may result in: Improved fuel economy. Decreased engine temperatures. Minor increases to engine power.
If you are thinking about deleting your truck, please reconsider. The main reason is that, first and foremost, it is highly illegal. Removing any emissions device on a diesel engine or adding a non-SMOG-compliant product carries a punishment of up to a $5,000 fine per unlawful part installed.
If the DPF is released with the vehicle at the point of sale, by law it is an offence to to remove and drive on public roads. Fines of approximately $10,000 to $12,000 if you are caught driving a vehicle without DPF that is fitted with one from factory.
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.
Perhaps the most critical disadvantage of removing DPF is the increase in soot and particulate matter volume in the air.
As a result, the infamous diesel particulate filter (DPF) came into being in 2007, and diesel exhaust fluid (DEF) was introduced in 2010 into the exhaust stream to reduce particulates and NOx.
If you're MOT savvy, you might already know that current emissions tests carried out as part of a standard MOT are not sensitive enough to show whether a DPF is fitted. It is therefore irrelevant that a smoke opacity test may be passed without one; DPFs are designed to produce much cleaner exhaust emissions than that.
Can you just remove your DPF? In short, no. It is illegal to drive a diesel car without a DPF, as by removing it your car will no longer meet emission standards.
The disadvantages are numerous and above all not without consequences for your car : An engine failure. A DPF wrong removed and an improper reprogramming of the engine map can put your car at serious risk.
Due to the extensive reliability issues that an EGR can cause, people take it upon themselves to make modifications to the EGR. You should know that any of these modifications are illegal, and the fines if you are caught are significant.
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.
If you turn off a diesel, you must remove all emission control equipment. These include the diesel particulate filter (DPF), the catalytic converter and the exhaust system. Next, you need to reprogram your ECU. A diesel extinguishing tuner can do this by replacing the OEM software with a new program.
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.
In many cases, a proper DPF delete will result in gaining over 100 horsepower while improving your fuel mileage and the lifetime of your vehicle. Ask us about a Ford 6.4L DPF Delete Service, or service for your GMC, Dodge, or Chevy truck.
clean it! A diesel particulate filter is a device that traps unburned carbon particles, commonly known as fine particulate matter. These pollutants are produced during normal engine operation and the role of the particulate filter is to clean them out.
Toyota Australia has lost its appeal against a 2022 Federal Court decision over damages owed to owners of Hilux, Fortuner and Prados fitted with problematic diesel particulate filters.
Since 2009, manufacturers of diesel cars have been legally required to fit all diesel cars with DPFs, so all modern diesel cars have DPFs installed. Subsequently, the only way to find a diesel car without a DPF is to buy an older diesel car under 2.5l which was manufactured before the Euro 5 regulations.
