There are several ways to clean your DPF filter, you can either clear it yourself by burning the soot away or have it cleaned professionally by a garage. If the blockage persists, you will likely need to replace your DPF filter, which can be costly.
This will involve the mechanic running a DPF clean cycle which runs the car at a high RPM for a prolonged time. The ECU makes this cycle heat up the DPF filter to high temperatures, clearing the filter by burning its contents. Alternatively, a manual DPF cleaning process to clear the filter can be carried out.
It's not impossible to clean a DPF at home. But the risk is high. The filter is a very delicate component of your car. You can easily damage it during DIY cleaning.
How to unblock a DPF? 1) DPF Regeneration - Find a motorway near you where you can drive at 70+ MPH for 30-45 minutes; this should provide the optimal conditions for the regeneration process to complete.
How to clean a DPF while driving ? To properly clean the Diesel Particulate Filter while driving, you will need to ride. The highway represents an ideal ground for this exercise, but simple roads will do the business. Maintain an engine speed of at least 3,000 rpm.
Some garages can clean blocked DPFs, in a process called forced regeneration. This usually costs around £100 and, while it's not a 100% guaranteed fix, it's usually successful in removing the excess soot and allowing the DPF to work and automatically regenerate again.
A blocked DPF or obstructed exhaust will force your engine to work harder to expel exhaust gases, reducing available power and increasing fuel consumption.
Drive over 40 mph (64 kph) to begin active regeneration.
Begin driving and pay attention to both the engine and vehicle speed. Try to keep the engine speed around 2500 rpm. Active regeneration increases the temperature in the DPF to turn the particles into gas which can be expelled.
It's recommended that you use a hose or faucet with a high-pressure nozzle, and spray the DPF down with a narrow jet to thoroughly clean it out. Angle the water to shoot out through both ends; you should see a stream of dirty water exiting the filter, continue to rinse your DPF until this water runs clear.
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.
Once blocked though, turbo failure can occur very quickly. If you don't check for a DPF issue when installing a replacement turbo, there is a very high chance the replacement turbo will suffer the same failure, as it will be subject to the same operating environment as the previous unit.
The most common reasons for DPF blockages are: Short journeys where the engine doesn't reach optimum operating temperature; Clogged EGR Valve increasing diesel soot passed to the DPF; Faulty fuel injectors sending too much fuel to the air/fuel mixture; Incorrect engine oil upon servicing the car ; Turbocharger failure ...
Manual regeneration is often required when vehicles are driven at insufficient speed to allow regeneration to be carried out automatically by their engine management control software. The vehicle is already suffering with driveability and lack of power problems.
DPF deletion does not affect vehicles' engine performance, power generation and horsepower. It can improve performance by freeing up space in the engine bay and reducing weight. However, there are some potential drawbacks to consider before going ahead with a DPF delete.
It is illegal for drivers to use a car with the DPF removed, but it is not illegal for garages to take them out.
Using Redex DPF Cleaner (either when your light comes on or regularly as a preventative measure) will help the soot to burn away during normal driving, so that your filter clears, and the light stays off. This can save you a lot of time, money, and stress, as a new DPF will typically cost around £1,000.
If it gets bad enough, a dusty air filter can cause damage to the engine, catalytic converter, DPF filters, oxygen sensors, and other vital components resulting in costly repairs.
To make sure that the regeneration takes place, most manufacturers suggest that every few hundred miles, the car is driven for a period of more than 15 minutes at a consistent speed of more than 40mph. Doing this should kick-start regeneration and clear the filter.
How Long Should A Diesel Particulate Filter 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.
Benefits. JLM Diesel Particulate Filter Cleaner is one of the best diesel particulate filter cleaners on the market. JLM DPF Cleaner contains a high concentration of the active additive. There's no need to remove the DPF Filter, just pour the JLM DPF cleaner into your diesel fuel tank.
If the journey is too short or the vehicle does not have enough fuel the DPF regeneration process might not work. To allow the DPF to regularly regenerate it's advised the fuel tank is more than a quarter full, otherwise, the vehicle will opt to save fuel instead of redirecting it for DPF regeneration.
If you notice a reduction in the car's power, acceleration, or fuel efficiency, then it is likely time to get your DPF checked. If your car is emitting more smoke than usual, it could be a sign that the DPF is clogged and needs replacement. A blocked DPF can also cause a foul odour to emanate from the car's exhaust.
