My bongo is flashing dpf wat should i do. And in gear 3 it stops pulling


Dpf stands for diesel particulate filter which is sooted up in the exhaust system sometimes you can burn the soot out by running at high revs for a while in a low gear to burn out the soot if that don't work a new filter will need to be fitted but don't leave it to long as it can damage the engine and turbo which will need replacing the turbo that is

On my Peugeot 5009, why did the DPF warning light come on after only 23000 miles?


If this is a diesel eng the Diesel Particulate Filter(DPF) is plugged with soot. excessive idling can plug up the filter in several hours on some vehicles. Check your owners manual to see how to do a regen (burn) to clean out the filter. Sometimes just running eng hard at hwy speeds will burn out the soot also.

Error code 55 on vauxhall meriva whats it mean


Error 55 is Diesel Particulate Filters (DPF)
Reducing diesel soot emissions by 80%

If you're buying a new car and plan to use it mainly for town-based, stop/start driving it would be wise to avoid a diesel car fitted with a Diesel Particulate Filter (DPF) because of the possible hassle of incomplete 'DPF regeneration'.

The exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems - AA patrols are regularly called to cars with the particulate filter warning light on indicating a partial blockage of the filter.

Even if your driving isn't mainly urban/stop-start, changes to driving style may be required to get maximum benefit from these systems.

How do they work?
Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

As with any filter (think of the bag in your vacuum cleaner) they have to be emptied regularly to maintain performance. For a DPF this process is called 'regeneration' - the collected soot is burnt off at high temperature to leave only a tiny ash residue.

Regeneration may be either passive or active.

Passive regeneration
Passive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don't get this sort of use car manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process.

Active regeneration
When the soot loading in the filter reaches a set limit (about 45%) the ECU can make small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration. If the journey is a bit stop/start the regeneration may not complete and the warning light will come on to show that the filter is partially blocked.

It should be possible to start a complete regeneration and clear the warning light by driving for 10 minutes or so at speeds greater than 40mph.

If you ignore the warning light and keep driving in a relatively slow, stop/start pattern soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will have to take the car to a dealer for regeneration.

Expensive repairs
If you continue to ignore warnings and soot loading keeps increasing then the most likely outcome will be that you will have to get a new DPF costing around £1000.

DPF additives
The most commonly fitted type of DPF has an integrated oxidising catalytic converter and is located very close to the engine where exhaust gases will still be hot. This heat means that passive regeneration is possible.

There's not always space close to the engine though so some manufacturers use a different type of DPF which uses a fuel additive to lower the ignition temperature of the soot particles so that the DPF can be located further from the engine.

The additive is stored in a separate tank and is automatically mixed with the fuel whenever you fill up. Only very small quantities are used though so a litre of additive should treat around 2800 litres of fuel - enough to cover 25,000 miles at 40mpg.

You will have to pay to get the additive tank refilled at some time in the car's life, and we've heard reports of dealers charging up to £200 to re-fill a half empty tank.

AA experience
We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways.

On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases.

With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed.

There's no evidence in AA breakdown data that the problem's going away - newer car models seem just as likely to sufffer DPF problems if not driven 'correctly' as those built when DPF's were introduced.

Check the handbook
If you buy a car with a DPF fitted it's important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life.

Idles ruff


This is something that can be caused by bad gas or water in the fuel. Mechanically, there can be a problem with the Idle Speed Air Solenoid which is inside the intake manifold. This part can be looked up on the Internet for identification and using WD40 can be cleaned of soot. Some engines have manifold runners which can also be cleaned of soot.
The above problems often do not trigger a "Check Engine" alert or at least are going to give you driveability problems long before a Code is present.
There are gas additives which can help the car digest bad fuel. Then follow-up with a new fuel filter. As common practice, make sure filters and oil changes are fresh, to give your motor its best chance to perform.
Fuel samples are a good diagnostic method. Unfortunately with the EPA requiring sealed systems, getting a fuel sample is more difficult. Pressure needs to be relieved from the system, remove the fuel filter and take a sample at that point.
There are also products which can remove soot from some of the intake systems. But directly cleaning the system insures a better job.

WHY IS THERE DRY BLACK SOOT ON NISSAN SENTRA 1996 CAR STUTTERS AND LOSES FOR SO IT EVENTUALLY TURNS OFF


Black soot coming from the exhaust would be excessive fuel.
The list includes injectors, fuel pressure regulator, fouled plugs, faulty coil, dirty air filter, and so on.

Black soot in throttle body


Usually the throttle body sucks air in and soot from the engine won't come up the other way. Check that the air filter is clean and that the housing doesn't have any leaks in it that would allow dirty air to bypass the filter.

I have Hyndia Tucson 2006 Deisel. I have a problem in it. This problem is smoke heavily (Black) and there is no intention of any force during press the accelerator.


mean there might be fuel leaking into the engine or the air to deisel ratio is and not atomised correctly. the main causes are normally is the air filter that isnt allowing air into the engine. Fuel filter can also be at fault not allowing enough fuel in or allowing to much in the engine sometimes. This causes the chamber to burn it out. Fuel injector if fualty could allow to much fuel or not enough. My personal suggestion would be to run fuel injector cleaner first, then change the air filter. If that doesn't fix it change the fuel filter. I would go the cheapest route first. Is is prolly something simple

DPF FULL


The DPF is designed to 'Burn off' the soot deposits that accumulate, but in order for this to happen the exhaust has to become really hot. The DPF will fill up if the vehicle does a lot of short trips and the exhaust fails to get hot. The cure is a long hard drive
