These can be regenerated without harm to the engine. Volvo has a procedure for doing this. I have not seen it published for the general public. You should be able to politely ask a Volvo servicemen for the recommended procedures and they will generally help you out.

How do i do a dpf regeneration on a toyota dyna


normally most new diesel vehicles with diesel particulate filters give you a warning light when it is ready to regenerate.if you got your handbook it may explain the method, diesel vehicles that do more short distance driving need regen more often because the filter blocks with soot particles quicker. try driving on a motorway for about 30mins at high speeds and keep engine revs up using a lower gear perhaps? or you can try cleaner addative to add to the fuel.some vehicles have to go on diagnostic equipment to instigate regeneration.hope this helps

Anti poluution fault warning is lit up on my 307 hdi peogeot


In the exhaust is a soot filter known to PSA as a FAP. It regenerates [a sort of deliberate chimney fire] and burns some of the soot off every few thousand miles. The cerium additive is called Eolys [go Google] and is stored next to the diesel tank with a computer controlled dosing mechanism.

If you don't drive it long enough, fast enough; then the regeneration process won't commence and the filter will block. Take it for a 40 minute blast down a empty dual carriageway; it's unbroken time above 50 [around six minutes] that will start the process.

Alternatively; take it to your dealer

2008 Peugeot 207 HDi, It is giving an error message that Depollution System Faulty what is the cause and why?


this car is more than likely fitted with a particulate filter in the exhaust system which has a pressure sensor fitted to detect when it is blocked. that puts the warning on. make sure the exhaust has been refitted correctly, i.e no leaks, any sensor pipes/connectors are in place, or it could be a coincidence that the particulate is now blocked and needs replacing or regenerating, you can buy a fuel system cleaner that may help to regenerate.,try your local motor factors for help. the filter works by trapping soot particles in the filter but it gets blocked, and to regenerate it most modern cars do it auto by injecting excess fuel in to the engine to burn it off. like a self cleaning oven, but your car may need help to do this, hope this helps you.

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.

What does code p2459 mean?


Causes
- Exhaust leak
- Improperly installed or loose Exhaust Gas Temperature (EGT)
- Low engine compression
- Corroed fuel injector
- Water in the fuel system
_ fuel filter or water seperator fouled.
When is the code detected?
The P2459 will set if the Engine Control Module (ECM) detects that the average time between completed regenerations is less than a calibrated threshold.
Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
P2459 Description The particulates in the exhaust gases are collected by the Diesel Particulate Filter (DPF). When the filter becomes saturated with particulates, they are incinerated by a regeneration process. The regeneration process increases the exhaust gas temperature, warning the Diesel Oxidation Catalyst (DOC) first, the warning the DPF. The Engine Control Module (ECM) monitors the system with inputs from two Exhaust Gas Temperature (EGT) sensors 1 and 2 and the exhaust differential pressure sensor.

C5 hdi sx 2.2 keeps saying unblock diesel filter


this is not referring to the dieselicon1.png fuel filter. it is referring to the DPF Diesel particulate filter which is located in the exhaust system.
to unblock it you need to make a 40min journey at or over 2500 rpm
(50 mph in 4th gear) this is known as a regeneration run.it brings the DPF up to around 400 degrees which burns out the old soot particles this is a normal process during normal driving but too many short /slow trips can cause a blockage in the filter

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
