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.
The easiest and cheapest method of DPF filter cleaning is by driving the vehicle for a long-distance at high revs per minute. Doing this increases the heat of the exhaust and burns the soot blocking the DPF filter. It's best to drive on a motorway or A road where you can keep the vehicle at a consistent speed.
All you have to do is get your car on an A road or motorway on a regular basis, such as every 300 miles. You then need to run it for 10-20 minutes at speeds in excess of 40mph. This will heat up your exhaust and burn off any soot in the filter.
A DPF clean can take as little as 20 minutes to complete.
How long does DPF regeneration take? Passive regeneration will take around 30-50 minutes to complete at speeds over 40mph, while active regeneration can be completed in as little as 10 minutes at the same speeds.
Most DPFs will automatically clear as they're used but on rare occasions, in specific circumstances, they may get blocked and require manual cleaning. In normal use, a DPF cleans or regenerates itself by reaching a sufficient temperature to burn off the excess soot.
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.
Like all Redex fuel additives, our DPF Cleaner can be added to a full or partially full fuel tank as and when required. It's also safe to use with other products in the Redex diesel fuel additives range.
The easiest and most effective way to de-clog and maintain your DPF filter is to use a combustion catalyst called FTC Decarbonizer. This DPF cleaner has been used successfully in many 4WDs, trucks and bus engines where carbon and soot related problems have started destroying engines.
So what's the answer? Your DPF regenerates because of excessive exhaust soot overwhelming the DPF. Exhaust soot is the product of incomplete combustion, the soot is actually partially burned fuel. Soot creates back pressure and the regeneration is triggered and your headaches begin.
The DPF needs to be cleaned regularly, through a process called regeneration, either active, passive or forced regeneration, the accumulated soot is burnt off at high temperature (around 600°c) to leave only a residue of ash, effectively renewing or regenerating the filter, ready to take on more pollution from the ...
A forced regeneration can be performed by any service shop with the appropriate diagnostic software. The cost for a forced regeneration varies. Generally, it is between $300-$700 depending on the technician's required diagnostic time and the length of time your DPF regeneration lasts.
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.
A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.
The cleaner is extremely simple to use. All you have to do is pour the correct amount directly into your fuel tank just before you will up with diesel.
Driving with a low fuel tank. Regeneration will not take place with less than a 1⁄4 of a tank of fuel.
For on-highway vehicles, the DPF should be pulled off for its first cleaning after 150,000 to 200,000 miles, and then every 100,000 miles after that for preventive maintenance cleaning, Anderson notes.
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.
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.
"Maximum court-imposed penalty for an individual is $22,000!" Is a DPF delete legal? Okay, so the $22,000 question: is it legal, and can you get fined for deleting the DPF? The short answer is, yes you can get fined, and no, it's not legal.
How long should a DPF last? 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.
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.
