How do I unblock my DPF filter?
Under normal driving conditions and with a properly functioning DPF, the filter should only need to be cleaned every 20,000 to 40,000 miles. However, through passive regeneration by driving for 30 to 50 minute run at sustained speed on a motorway or A-road it will help clear the filter. What does a dpf replacement cost? The price for the spare part itself ranges between £400 and £1000. As mentioned, a replacement of the particulate filter is more expensive than a dpf cleaning, but sometimes it is necessary.Diesel particulate filter replacement The price range of DPFs ranges from £750 to £3,500, depending on the make and model. This includes parts and labour. It can take several hours to replace your DPF, which is why it is better to leave it to the professionals to ensure it is completed correctly.Average Lifespan Of A DPF Under typical conditions, a Diesel Particulate Filter (DPF) is designed to last anywhere between 120,000 and 200,000 kilometres. However, this range is not a guarantee, as the actual lifespan can vary widely based on several factors.
How many revs to clear DPF?
DPF Warning Light Explained Nevertheless, a general rule of thumb to follow is that you should run the engine at least 40 mph and at least 2500 rpm. Ignoring the DPF light, or failing to clear the blockage in a timely manner, will lead to continued soot build up in the DPF. DPFs are designed to reduce soot emissions by 80 %. They need to empty themselves—this is called regeneration. A town-based, stop-start driving style may hinder this regeneration. A DPF warning light is a sign to take a 10-minute drive at a higher speed so the DPF can regenerate.How to clear the DPF light. To clear the DPF light, try the following steps: Go for a regeneration drive: Take your vehicle on a motorway or dual carriageway and drive at a steady speed (around 40-50 mph) for 20-30 minutes. This helps the DPF reach the necessary temperature to burn off the accumulated soot.The simplest way to sort out a blocked DPF is to engage in ‘passive regeneration’. Simply put, this is driving on a motorway or A-road at a sustained speed for 30-50 minutes to allow your exhaust temperature to reach the point where it can cleanly burn off the excess soot.For passive regeneration, regularly drive at motorway speeds for 30 minutes to allow the exhaust temperature to rise and burn off soot naturally. If active regeneration is required, follow the dashboard prompts when the DPF warning light appears.
Can DPF be cleaned manually?
The simplest method is to use additives that are mixed into the fuel. These additives help to burn off soot during driving. Another method is to remove the filter and clean it manually with special chemicals or compressed air systems. Use a specific DPF cleaning solution, available at most automotive stores, and spray it generously onto the filter. Let it soak in for about 20 minutes, giving the solution time to break down the accumulated soot. Afterwards, rinse the DPF thoroughly with water, using a pressure washer if possible.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.In these cases, the DPF must be manually cleaned by adding a cleaning treatment to loosen and dissolve the soot and allow it to pass through the filter. This is done by applying the product through the pressure sensor tube or by removing an oxygen or temperature sensor and applying the product directly to the filter.JLM DPF CLEAN AND FLUSH TOOLKIT This kit cleans very dirty diesel particulate filters without dismantling and saves the motorist significant costs.
How long does it take a drive to clear DPF?
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. If this works, consider a regular drive along a motorway regularly to allow the regeneration process to complete. Regeneration. Some say driving at speeds of over 40mph for 10 minutes using at least 2500 RPM and sticking in 3rd/4th gear can turn off your DPF light from your dash.You might be able to resolve the light by continuously driving over 40mph for around 10 minutes. The following signs indicate that DPF regeneration is taking place: Fuel consumption slightly increases. The cooling fans are running.
What gear do you drive in to clear DPF?
If you have mostly driven your diesel car around town and notice that the DPF is becoming blocked, take the car out on a long, motorway journey in an attempt to burn off the soot. On the motorway or dual carriageway, use a gear down (5-speed use 4th and 6-speed use 5th) to increase the engine revs. 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.It is then recommended that you drive for around 15 minutes on a stretch of a quiet road with a reasonably high-speed limit, trying to keep the revs at between 2 and 2. This will give the cleaner plenty of time to work its way to the DPF and to help to burn off any excess soot which has collected there.Removing the DPF from your vehicle can improve performance and fuel economy, but it is illegal in many places and can result in fines. Without the DPF filter, the vehicle will emit more pollutants, which negatively affects the environment.Use a DPF Chemical Cleaner Finally, one very quick and easy way to clean a diesel particulate filter is to use specialty-made DPF chemical cleaning solutions. For most of these cleaning additives, you won’t even need to remove the filter!
