DPF needs to be cleaned, but you'll also need to have the monitors reset. Most likely have to take it to the dealer.

Read the owners manual or call the V.W. service department. sound like you need to clean the filter. If you ignore the warning more then 3x you will cause damage and it will be costly.

SOURCE: Hi I HAVE A ISUZU WIZZARD 3.0 WITH 4jx1 engine,it

Hi, you problem is the rail oil pressure sensor having a high voltage input -  P0193 code set . This will also cause your faults . 
Change the sensor which is under the cam cover and the smaller of the two there and it will run ok .
You need the sensor set up on a tech II after fitting to run at its best.

SOURCE: how to fix and clean the mazda 5 diesel

You can clear these if less than 60% blocked by giving the car a good blast on the motorway going through the revs. If your car is on limp mode you do need to replace the particulate filter as the blockage is too much to regenerate. I have found a company that does these very cheap and are technicly brilliant i had many questions and they seemed to answer correctly with confidence. They supplied the part to me for £500, i have checked from this for the automotive solutions guys that did it for £450 but couldnt find them which is why i went with these. The company is Onlineautomotive.co.uk and i spoke to someone Called Darrell. There number is anyone wants it is 0844 880 4149 he did giv me a direct number but im sure he wouldnt want me to list that on here as its his work mobile.

Check for DPF in Volvo C30, S40, V50, C70 (diesel particulate filter, FAP, 2.0D...


Check if your Volvo C30/S40/V50/C70 has DPF (diesel particulate filter) / FAP (filtre ? particules) installed. Volvo is using this filter in cars with diesel engines like 1.6D, 2.0D, D2, D3, D4, D5 to reduce emission and meet Euro emission standards.
There are three ways to check your Volvo for DPF: by VIN number, with hidden menu and by checking ADM module under the hood.

Need to fix my 2007 Dodge Ram 3500 dually,6.7 Cummings diesel, check engine light code P2002


P2002 - Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
Description: The powertrain control module(PCM) monitors the efficiency of the diesel particulate filter for a concern. The efficiency of the filter is determined by the amount of restriction in the filter for a certain exhaust flow rate. The diesel particulate filter is preconditioned for 5,000 km (3,107 miles) before the PCM begins to monitor the level of restriction. The test fails when the measured level of restriction is less than the expected level calculated by the PCM. Possible Causes:
  • Dirty air cleaner element
  • Recent manual or thorough diesel particulate filter regeneration
  • Aftermarket accessories and performance modifications
  • Modified tailpipe
  • Exhaust leaks before or near the diesel particulate filter pressure sensor
  • Leaks in the diesel particulate filter pressure sensor connecting hose
  • Damaged diesel particulate filter
Diagnostic Aids: Check for leaks in the exhaust system. Check for aftermarket exhaust accessories and performance modifications that decrease the exhaust restriction. If a new diesel particulate filter was recently installed, verify the diesel particulate filter parameter reset procedure was carried out.

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.

My 2007 Dodge cummins 6.7 is telling me to perform service and the catalyst is full. How do I fix this problem myself?


Intervention Regeneration Strategy - EVIC
Message Process Flow (Catalyst Full Message)
(6.7L Diesel Engines Only)

Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards, resulting in the
lowest emitting diesel engine ever produced.
To achieve these emission standards your vehicle is
equipped with state of the art engine and exhaust system.
The engine and exhaust aftertreatment system work
together to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seamlessly integrated
into your vehicle and managed by the Cummins
6.7L engine Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust system's
catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, the overhead console in your vehicle has
the ability to alert you to additional maintenance required
on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC):

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.

Perform Service
The 6.7L Cummins engine utilizes a Closed Crankcase
Ventilation (CCV) system, EGR Valve and a EGR Cooler.
This system filters and recycles gasses produced in the
crankcase during the normal combustion process. Perform
Service will be displayed on the overhead console of
your vehicle if the CCV filter, EGR Valve and EGR Cooler
is due for required maintenance. The CCV filter is located
on the top of the engine valve cover. For additional
information, see your local authorized dealer.
Catalyst Full See Owner Manual
Catalyst Full See Owner Manual will be displayed on the
overhead console of your vehicle if the exhaust particulate
filter reaches 80% of its maximum storage capacity.
Under conditions of exclusive short duration and low
speed driving cycles, your Cummins engine and exhaust
aftertreatment system may never reach the conditions
required to remove the trapped PM, if this occurs Catalyst
Full See Owner Manual will be displayed on the
overhead console in your vehicle. If this message is
displayed you will hear one chime to assist in alerting
you of this condition.
Catalyst Stat::::::::::80%
Catalyst Stat::::::::::80% will replace the message Catalyst
Full See Owner Manual after it is displayed for one
minute. The engine Powertrain Control Module (PCM)
will continue to monitor the amount of particulate matter
trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.

By simply driving your vehicle at highway speeds for as
little as 45 minutes you can remedy the condition in the
particulate filter system and allow your Cummins engine
and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.
Catalyst Stat:::::::::::80%, 90%, 99%
Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an extended
period of time after the initial warning notification,
the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.

CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it's capacity the
overhead console in your vehicle will chime twice and
display the message CATALYST FULL SERVICE REQD.
At this point the engine PCM will register a fault code,
the instrument panel will display a MIL light and the
engine PCM will derate the truck reducing its horsepower
and torque output.
The PCM derates the engine in order to limit the likelihood
of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.

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

Passat 2006 2.0 tdi 140 engine won't start dash warning says either "engine fault, garage" or "low oil pressure".


Exhaust pressure sensor a possibility if it has a DPF (diesel particulate filter). Has it had its fuel pump recall, the oil pressure light could be just the constant cranking and running the battery low.

Why does the dpf light keep coming on my masda


I've found the following info at mazdaforum.com , which I will reproduce word for word:

If the Diesel Particulate Filter indicator illuminates continuously - Drive the vehicle at an engine speed of 2000rpm or higher and a vehicle speed of 40Km/h (25mph) or more for about 10 to 15 minutes to remove the particulate matter. The engine sound and smell may change as the particulate material is being removed.

If the Diesel Particulate Filter indicator flashes - Take your vehicle to a Mazda Authorised Repairer as soon as possible to prevent damage.
