The Truth About Diesel Particulate Filter Problems (DPF Problems) | Auto Expert John Cadogan
In theory a DPF needs no maintenance - it’s just a steel chamber up near the engine full of Cordierite or silicon carbide designed to trap microscopic soot, and then periodically the computer turns the chamber into a furnace by injecting extra fuel, thus burning the particles into a less harmful state. But DPF blockage is a symptom, not a problem. Like a headache is a symptom, and drinking 14 bottles of tequila last night is the problem. Replacing the DPF usually doesn’t cure the problem - in fact, it could mean you’ll be back for another replacement in a few weeks-to-months if they don’t actually cure the problem. The problem could be as simple as: you didn’t go for regular highway drives you were supposed to. I’m talking 80km/h or above for a total of an hour or so, minimum, every fortnight. City driving is generally inadequate to allow a filter-regenerating burn. But many people who experience DPF problems are actually doing more than enough requisite highway driving - so it’s often not that. It could be a problem with the inlet air plumbing - lots of DPFs fail this way. See, a modern diesel is turbocharged, and that means the inlet air plumbing is pressurised between the turbo and the engine inlet. And there’s a lot of plumbing: hoses connect the turbo outlet to the Intercooler inlet and then there’s a dirty big plastic elephant trunk thing in the case of Subaru - so there’s a lot of potential for inlet air leaks. The problem here is: the mass air flow sensor, AKA the MAF sensor. The MAF sensor measures the mass of air going into the engine, in real time. That’s important because the computer uses that information to determine how much fuel to inject. Only two things go into your engine - air and fuel. And the ratio of the two needs to be bang-on. Measuring the mass of air makes sense because it self-corrects for pressure and density and the generally squishy properties of air. The mass is all that matters. But if there’s a leak in the inlet air, downstream of the MAF sensor, because a hose gets a tiny crack in it over time, some of that air that the MAF sensor measures is not actually going into the engine. And that means the engine will be over-fuelling, continuously, under Boost, and that’s going to produce a whole bunch of additional carbon that will be like opening the Book of Revelation inside your DPF. That’s bad. Four tiny horsemen in there, wreaking carbon-based, end times havoc. Induction leaks are real killers of DPFs - so if you are buying a used diesel car or SUV, it could be an entirely prudent idea to replace all the induction plumbing hoses as a pre-emptive strike against early DPF failure. Especially on the wrong side of 50-60,000km. Over-fuelling is sometimes also caused by leaky fuel injectors - so I’d be getting a diesel specialist involved in the proposed purchase of any used diesel with a DPF - and not handing over the cash until there’s a clean bill of health from an expert. It’s also very bad to use the wrong engine oil. DPFs require a special low-ash oil - and there’s more than one grade of that, so make sure you get the oil selection exactly right for your car. Another way to kill your DPF with oil is via a leaky turbo oil seal. So I would absolutely not be letting those service intervals slide. Sticky EGR valves are another DPF killer - pumping excess crankcase vapour into the Exhaust. Faulty glow-plugs - also DPF-deadly - because they cause the engine to run too rich on start-up. And then there’s the differential pressure sensor across the DPF - all that does is measure the pressure drop across the filter. That tells the control computer there’s enough soot built up to trigger a regeneration. But if the plumbing to that pressure sensor gets clogged, the computer presumes no regeneration is necessary - even if the filter is in fact choking to death. I hope you can see that this is a complex system that, at times, to me, seems almost doomed to fail. And the failure is hardly ever intrinsically due to some deficiency in the DPF itself. In general, just replacing the DPF will lead to just replacing the DPF again - in a few weeks to months. And nobody wants that - even though plenty of people do it. Often the dealership will be ill-equipped to solve your DPF problem. They are generally fairly crap at diagnosis Were I you, on the dreaded DPF merry-go-round - I would look for an independent diesel specialist with runs on the board with DPF diagnosis. It’s not rocket science ‘down there’ - but it is a bit complex for your average dealership Muppets who think taking orders from a scan tool is the same thing as being a mechanic.

What is DPF DEF EGR SCR? Protecting your Diesel
What is DPF? What is DEF? What is EGR, and what is SCR? They are EPA Emissions Controls added to your diesel performance truck by Ford, Dodge, and Chevy. These have an effect on your MPG and power as well as the life of your engine. 1World Filter and EXTREME engine protection systems by want to arm you with knowledge and more. Here we show you what all these acronyms are and how to protect against the side affects of these catalysts and devices, and even improve MPG, Performance, and radically reduce engine wear whether you have a DPF delete, SCR, & EGR delete or not. Soot and other abrasives in your oil can only be removed by a bypass filter. 1World/EXTREME™ bypass oil filter is the absolute best way to keep oil clean, with the only patented progressive filtering that doesn't plug easily like other fine bypass filters. Fuel and its destructive effect in oil can be minimized as well through the use of NASA-certified EXTREME WS2 oil Additive. Love your truck? Learn more: And Please forgive chemical formulas that are not perfectly balanced, and mispronunciations like "Nitrous Oxides" instead of "Nitric Oxides" and Nitrogen represented as N instead of N2, etc. DPF and SCR and CATs come in different orders on different engines and different years and with different manufacturers. The video information is just to present general basics of emissions controls and their effects on the engine and not meant to be a technical seminar with every variation explored and explained to put you to sleep at night. It's to give you enough knowledge to inspire and motivate you to protect that huge investment that is your diesel truck. Love it? Keep it clean! You're welcome.

Diesel Particulate Filters: Watch Out!
"Don't mess with the particulate filter," say the guys at TruckU. They suggest going with Banks Power for a good, clean tune and cooler, much safer temps.

DEF Frustration!!!
Working on my buddy's 2011 Duramax with a DEF problem. He already installed a tuner voiding the warranty, so the dealer wouldn't cover it. I told him he needs to just delete all that garbage.
