SOURCE: mazda 6 2o diesel replaced turbo new unit same

There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.

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.

SOURCE: 2008 Ford F250 6.4 turbo diesel, have 3 DTC codes

Code1 p0088 = Fuel rail/system pressure too high
code 2 p0087= Fuel rail/system pressure too low
code 3 p2291 = Injector control pressure, engine cranking-pressure too low. I would suggest clearing the codes first and then rechecking to see which (if any) codes reappear. Good Luck.

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

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.

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
