The DPF system is fitted to a wide range of cars and in fact is being installed on almost all new Diesel engines so the problem will in future become more and more common, however, at this moment in time we’ve put together a small list of the most common cars which we’re having to deal with on a weekly basis suffering from the DPF problems: Are there any problems with the DPF system? Here’s how I permanently unblocked the DPF on my Vauxhall Zafira (and other diesel cars too)Ĭalling around, within half an hour, I found several independent garages in Ontario and Quebec that would remove and delete the EGR/DPF systems from almost any EPA-compliant engine. This rarely works because the car filter is so badly blocked that a replacement may seem to be the only remedy. You may have heard that you can regenerate a DPF Filter by giving the car a run down the motorway. Is there a way to unblock the DPF filter? What is a Diesel Particulate Filter (DPF) A DPF is a device designed and integrated into the Diesel Engine exhaust system to trap and remove Diesel Particulate Matter from the exhaust gasses of the diesel engine. ![]() What is a Diesel Particulate Filter ( DPF )? In short, we can help correct problems with DPF and poor performance at the same time. ![]() Do you need DPF delete that saves you money? Motorists tend to avoid repair due to the expense of cleaning, remapping or replacing the filter, particularly if the car still runs pretty well but there is an engine warning or glow plug light flashing. Depending on your car type, driving with a faulty DPF filter can be illegal. The computer uses exhaust temperature and pressure before, at, and after the dpf to measure how plugged the dpf is and when it's time to perform a regen.Is it illegal to drive with a faulty DPF filter? They are thermocouples that measure exhaust temperature. The other wires you see going to the exhaust before and after the DPF filter are not spark or glow plugs. Again, I don't care what the tech at the dealership says about those lines, if he says they are fuel lines (which I hear all the time), he is an idiot and you should remove your truck from there as quickly as possible. They have the long metal tubes on them to get the temperature of the exhaust they are measuring down before it reaches the sensor. The metal lines everyone sees on the side of the DPF filter are for a pressure sensor that is usually attached to the side of the transmission or frame. A small shot of fuel is pushed out with the rest of the exhaust gas. As I stated above, the fuel needed for cleaning the dpf is entered into the engine cylinders by route of the regular fuel injectors during the exhaust stroke of the engine. The frequency of this cleaning cycle is different from vehicle to vehicle depending on use, mileage, and engine condition. Once the computer gets readings from the sensors in the exhaust that the filter is flowing an acceptable limit again, it ends the regen cycle. The raised exhaust temps and the small amount of fuel then burn out the particulate (soot) that the DPF has collected since it's last regen. The computer then opens the EGR (exhaust recirulation valve) introducing hot exhaust into the intake to help get get exhaust gas temps higher and also injects a small shot of fuel into the cylinders when the exhaust valves are open. You may have noticed a light on your dash from time to time that alerts you that the DPF is in "regen" or "cleaning filter." Basically what is happening during this process is that the engine's computer has decided from the information that it receives from the sensors installed in the exhaust that the DPF has filled up past it's acceptable limit. Once the DPF has become "full" of soot, it will need to have a regeneration cycle in order to burn all the soot out. The DPF will capture 90% or better of all harmful diesel emissions. You may have noticed if you have one the 07+ diesel pickups that it never puts out any black smoke at all. A diesel particulate filter (DPF) is a device that traps the soot and unburnt fuel from diesel combustion. Since 2007 all Dodge Cummins 6.7, Ford Powerstroke 6.4, and Chevy Duramax 6.6 trucks come from the factory equipped with a particulate filter to meet tougher emissions standards. This is a question we get a million times a day. ![]()
